Wiring two ESCs to one battery is a fairly simple process. You will need some supplies to complete the job, such as two electronic speed controllers (ESC’s), one battery, wiring, and electrical connector(s).
Begin by connecting one ESC to the positive terminal of the battery and the other ESC to ground. Then, create a parallel connection between the two ESCs by connecting the positive and negative terminals (or leads) of each ESC together.
This will ensure that each ESC will draw an equal amount of power when the battery is being discharged.
Once the individual ESCs and the battery are wired together, use the provided wiring and electrical connectors to connect the two ESCs to each other. You will need one connector for the pitch, roll, and throttle inputs and another for the ground or negative input.
It may also be necessary to utilize a connector for the power input from the main battery.
Make sure that the wiring between the ESCs and the battery are secure and not loose, as this could result in a short. If everything looks correct, your setup is complete and you are ready to use your system.
If you have any questions or experience any difficulty during the wiring process, have your setup checked by a qualified professional.
Can two brushless motors run off one ESC?
Yes, two brushless motors can run off one Electronic Speed Controller (ESC). Brushless motors require ESCs to operate because they don’t have an on/off switch like most other motors. An ESC is an electronic device used to control the speed of brushless motors, which are popular in radio-controlled airplanes, cars, trucks, and boats.
In many setups, multiple brushless motors can be connected in parallel to one ESC to allow for better control of the power the motors receive. This is a great way to achieve a powerful, efficient, and lightweight system.
It also reduces the number of components needed and simplifies the wiring setup. When connecting two brushless motors to one ESC, it is important to make sure that both motors have the same RPM rating, voltage rating, and pole count because different types of motors cannot be combined.
There are motor and ESC combinations made specifically for this purpose, which can save time and effort when trying to find compatible motors and ESCs.
How do I match battery to ESC?
When matching a battery to an ESC, it is important to consider the specifications of both components. The battery should have an adequate number of cells, an appropriate capacity rating, and a voltage that is compatible with the ESC.
The ESC should be able to handle the current produced by the battery, have appropriate programmable features to suit your application, and the correct connector for the type of battery being used. It is important to double-check the ratings of each component and do some research to make sure they will be compatible before applying any power.
Additionally, when shopping for an ESC and battery, it is important to look for items that come with a warranty and authorized technical support if anything should go wrong. Following the manufacturer’s instructions is typically the safest way to ensure a successful pairing.
How do I connect my ESC to my receiver?
To connect your Electronic Speed Controller (ESC) to your receiver, you will need the correct plug(s). Depending on your ESC, you will either need a Solder Tail or flat plug. Once you have determined the correct plug(s), start by plugging the receiver’s throttle, rudder and aileron channels into the appropriate ports on the ESC.
Pay attention to the polarity of the plugs and [pins] on the ESC—incorrect polarity can damage both the ESC and the receiver. In most cases, the throttle channel should be the first port, followed by rudder and then aileron.
After that, you simply plug in your battery to the ESC. Make sure the battery is securely connected, then double check your ESC connections and power it up. If any of your channels are not working as expected, adjust the settings with the small adjusting switches on the ESC.
Why does a ESC have 3 wires?
An Electronic Speed Control (ESC) has three wires because it needs three wires to control it. The three wires that are used in an ESC are the power, ground, and signal wires. The power wire supplies power to the ESC and the motor.
The ground wire provides a return path for the electrons and sends the electrical current back to the power supply. The signal wire connects the ESC to a transmitter which sends a signal from the transmitter to the ESC, allowing the user to control the motor.
Most ESCs also have an optional fourth wire which is used to connect the ESC to a BEC (Battery Eliminator Circuit) for supplying power to other accessories on the vehicle.
By connecting three wires to the ESC, it can be operated in real-time without manual adjustments. This includes setting the throttle and programming directional settings. Having three wires also makes it easier to repair and troubleshoot components that the ESC is connected to.
How many amps do I need for ESC?
The number of amps you need for your electronic speed control (ESC) depends on a few factors, such as the size of the motor you are using, the type of propulsion system, and the type of terrain you will be navigating.
Generally speaking, the larger the motor, the more amps you will need. Similarly, if you intend to be navigating on rugged terrain, or faster speeds, you will need more amps.
In general, most electric motors require 50-100 amps of current, depending on the application. For example, a 540 or 550-size electric motor that is typical of what you might find in a 1/10th scale on-road or off-road vehicle would require approximately 70-100 amps of current, depending on the gearing you choose to use.
However, if you are running a larger 1/8th scale electric monster truck, you will most likely need an ESC with at least 200 amps of current.
In summary, the number of amps you need for your ESC will depend on the application. It is important to research the motor you intend to use and the terrain you plan to navigate before choosing an electronic speed control.
How much voltage does an ESC need?
The amount of voltage an Electronic Speed Controller (ESC) needs will depend on the size of the motor and the type of use it is intended for. Generally, an ESC will need at least 6 to 8 volts for it to function properly.
If the motor is very large or will be used for very high speed or torque applications, the ESC may need up to 14. 8 volts. For most applications, a LiPo battery with 11. 1 or 12. 6 volts is sufficient.
When in doubt, it’s best to check the manufacturer’s specifications to determine the optimal voltage for your specific ESC and motor combination.
Does voltage matter for ESC?
Yes, voltage does matter for ESC (Electronic Speed Controllers). The ESC is used to control the speed of a DC motor and the amount of power supplied to the motor. The amount of power is determined by the voltage supplied to the ESC.
If the voltage is too low, the motor will not be able to reach its full speed potential. If the voltage is too high, the ESC can become damaged due to the increased power it supplies to the motor. Therefore, it is best to make sure that the voltage supplied to the ESC is appropriate for the application it is being used in.
Does receiver get power from ESC?
No, the receiver does not get power from the Electronic Speed Control (ESC). Rather, the receiver gets its power from a dedicated power source such as a LiPo battery. When the motor is running, it will produce interference that can affect operation of the receiver.
Because of this, it is important to use a separate power source for the receiver to avoid any power spikes or loss of control. Additionally, isolating the power for the receiver using a separate battery can help protect the motor from damage.
How do I know what ESC I need?
When selecting the right ESC for your needs, the first step is to determine the expected load. The ESC should be rated to handle the current draw of the motor at peak load, so it is important to select an ESC with an amperage rating that is equal to or higher than the expected current draw of the motor at peak load.
This can sometimes be challenging if you’re unsure of the exact requirement.
It is important to check the specs of your components to make sure the right ESC is being purchased. It is also important to note that some components voltages may not be compatible with the ESC’s voltage range, so additional components such as voltage regulators may be needed.
In addition, when purchasing an ESC it is important to make sure the size and weight of the ESC are compatible with your application, as the ESC should be light enough to prevent an excessive load on the motor.
Lastly, make sure the ESC supports your type of motor – such as brushed or brushless – as well as the connector size that plugs into your motor.
Ultimately, the ESC you end up selecting will depend on your particular application requirements. As long as you take the time to research and select a compatible ESC, you should be able to enjoy the performance and reliability of your ESC for quite some time.
How do you size ESC?
Sizing an Electronic Speed Control (ESC) requires knowledge of a few basic pieces of information about your project. The most important attribute to consider when sizing an ESC is the maximum current draw of your motor.
You will also need to factor in the type and number of batteries or power supply you are using, as well as the operating voltage of your motor and any desired features such as braking, reverse, or over-programming that you may need.
When properly sizing an ESC, it is important to make sure it can handle the peak current draw of your motor at full throttle. This is also referred to as the “stall current”. To properly determine the stall current of your motor, look up the specification in the motors data sheet or subtract the no-load current spec from the full-load current to get an approximation.
It is important to ensure that the ESC you choose is rated to handle the stall current of your motor.
In addition to the current requirements of your project, you also need to consider the operating voltage of your motor. Make sure the voltage of your battery or power supply meets the voltage requirements of your motor and that the ESC you choose can handle the voltage of your power source.
Choosing an ESC with additional features may also be important for your project. Many ESCs have integrated braking, reverse programming and throttle curves which can be adjusted to better suit the needs of your specific application.
Be sure to take the time to research the features available and select an ESC that includes the features that you need.
In conclusion, sizing an ESC requires knowledge of the maximum operating current of your motor, the operating voltage of your motor, and desired additional features. Once you have identified the size ESC you require, you can confidently select an ESC that can meet your needs.
How do you calculate ESC size?
The size of an ESC (electronic speed controller) depends on the type of motor it is controlling. Generally, ESCs are rated according to the watts of power they can handle, the amps of current they can output, and their maximum cell count; each of these considerations plays into the proper ESC size for your motor.
When determining the size of ESC for a motor, it is important to consider the following:
1. Power: The ESC’s power rating should always exceed the wattage rating of the motor that it is controlling. Generally, the motor should pull no more than 80% of the ESC’s power rating, so this factor should be taken into account when comparing your motor’s listed wattage with the ESC’s power ratings.
2. Current: The ESC’s maximum current output and the motor’s current rating should be considered. The ESC should have a current rating greater than the motor’s maximum current draw, so that it can handle the peak draw of the motor.
3. Cell Count: The ESC’s maximum cells should be at least one more than the maximum number of cells that the motor can handle. This is to ensure that the ESC will always stay within its limits.
Once you have determined the power, current, and cell count requirements of your ESC, you can compare these to the ratings of different ESCs to determine the size of ESC you need. Ultimately, selecting an ESC depends on the motor and its performance requirements, and the ESC size you buy should match or exceed the motor’s requirements.
Can you over Volt an ESC?
Yes, you can over volt an ESC (Electronic Speed Control). When an ESC is over volted, the electrical power that the ESC is receiving is higher than the rated voltage of the ESC. This means that the ESC will be receiving more electrical power than it is designed to handle, and it can damage or destroy the ESC if the over voltage is too high.
To help avoid damaging or destroying an ESC, it is important to use a voltage regulator to maintain a consistent voltage level. Additionally, users should either stay within the ESC’s specified voltage limits or acquire and use an ESC specifically designed for higher voltage applications.
What are the 3 wires on a brushless motor?
The three wires on a brushless motor are typically referred to as the A, B, and C wires. The A wire is connected to the phase A winding, the B wire is connected to the phase B winding, and the C wire is connected to the phase C winding.
The windings on these motors are usually numbered in such a way that when the wires are connected in the correct order and the motor is powered, the motor will spin in the correct direction. Depending on the motor, the wires may be colored differently to indicate which winding they represent or they may be labeled A, B, and C to indicate which winding they each represent.
Each winding can also be tested with a multimeter to identify which winding it is should the labels be unclear or not present.
How do you test a 3 wire brushless motor?
Testing a 3-wire brushless motor requires the use of a multimeter to measure both resistance and voltage. First, disconnect any power sources from the motor. Then, use the multimeter to measure resistance between each of the three wires.
Each pair should measure at around 0. 1 – 0. 3 ohms, with only slight variation between each pair. If the variation is too large, it may indicate a faulty winding in the motor. Next, measure the voltage at each wire, and compare it to the other two.
They should be fairly close in reading. A large difference between them could signal a poor connection somewhere in the motor. Finally, connect a powered battery or supply and measure the speed at each wire using a voltage-reading device.
Each wire should be producing the same amount of speed, otherwise this is an indication of a bad winding or short circuit. Testing each aspect of a 3-wire brushless motor should not take more than a few minutes, as long as you have the appropriate instrumentation on hand.
