What ESC to use? (2024)

What ESC to use?

In general, the ESC should be rated 10-20% higher than the motor's maximum current at 100% throttle. For example, if your motor produces 10A at full throttle, you should use a 12A or 15A ESC. For safety reasons, you can also choose some ESCs that are equipped with temperature sensors.

How do I choose an ESC for my plane?

Choose an electronic speed controller that is rated for slightly more than what your motor will pull at full throttle. Too much current will damaged an electronic speed controller very quickly! On the same token, too big of an ESC is dead weight that will adversely affect the performance of your airplane.

Can I use any ESC with any motor?

Some ESC's can only power sensorless motors, while other only work with sensored motors. The power of a motor is usually indicated in “kv” or “turns”, or both. A motor's kv refers to its rpm per volt of electricity.

How do you match ESC to motor?

ESC's are rated in amps and maximum voltage. Your motor has a Kv rating which approximates the no load speed for whatever voltage (i.e., rpm per volt) is attached to it. In order to know how "big" (amperage) your ESC needs to be, you need both the load and Kv for the motor.

How do you match ESC with brushless motor?

How do you match a brushless motor ESC? You just match the voltage rating, and buy an ESC with sufficient current to handle the load you plan to run. For example a motor might be rated for say 6S and 50 amps maximum.

What are the different types of ESC?

There are two types of ESCs—brushed and brushless. Brushed ESC is used for a brush motor, brushless ESC is used for a brushless motor. Depending on the type, their construction and design are different. Brushless ESCs are more advanced and costly than brushed ESCs.

Can you run 2 motors off 1 ESC?

It may work, but it the motors will likely lose synchronization and stall and/or damage the ESC. However, as much as two motors can operate from a single source, making them operate in the opposite direction will work readily by reversing two of the phases of of one of the motors.

Is a higher amp ESC better?

The ESC acts like a regulator between the battery and the motor, controlling the power to the motor. So, a higher amp ESC has a larger capacity to deal with the motor drawing more current without issues. Electric power is measured in Watts. The ESC is rated for some max volts and some max amps.

Why did my ESC catch fire?

I would guess you either got the wrong size esc, the esc was a knock off and just weak, or the motor is bad. You can and should check the motor with a multimeter as its a high probability when the esc went it took the motor with it and or the opposite.

Can I use any ESC with any brushless motor?

Any brushless esc will work with any brushless motor. Making sure you have a large enough esc is another thing. That ESC will work fine for that motor, as the motor is rated at 18A max and the ESC will handle up to 40A.

Can you mix and match ESC and motor?

Motors/Esc are pretty much mix and match, if you are going to run them pay attention to the amp rating of the esc. Higher turn motors draw more and therefore need higher rated escs. There are also sensored and sensorless motors/escs, that is just a little 4th wire between the 2 that helps the run/sync more smoothly.

Do you need two ESCs for two motors?

You can, but it's not recommended. First of, you will need an ESC that can handle twice the current of what one motor consumes. The motors will also be seen as one single motor by the ESC, so of one of them has an error or becomes out of sync, both of them will stop.

How do I choose the right ESC for my RC brushless motor?

How to buy an ESC?

While choosing an ESC for your drone, it's important to take into account the current rating, also known as the ampere rating. This rating is determined by the maximum current drawn by the motor at full throttle and should be selected after choosing an appropriate motor size.

Do you need an ESC for each motor?

Brushed and brushless motors both require escs, but an esc is specific to brushed or brushless. IE, you have to buy the right type. There can be a few factors in choosing the correct esc, but the biggest factor is getting a current rating somewhat larger than the motor will draw.

How do you size an ESC?

To size an ESC, the most important specification is the maximum current capacity. In short, you want the maximum current capacity of an ESC to be larger than the maximum current draw of the motor/propeller combination.

Can you run a brushless motor without an ESC?

No. A brushless motor needs a motor controller to switch the power to the coils at the right times to keep the motor turning. There's no way to make the motor do anything useful without a brushless motor controller.

How do you match battery to ESC?

Your ESC is rated for operation at 6-12V, which suggests that you could use a 7.4V or 11.1V Lipo battery. Battery capacity and 'C' rate should match the expected current draw and run time. For example if the average current draw is 15A and you want to get 10 minutes then you need at least 15*(10/60) = 2.5Ah or 2500mAh.

What is standard ESC?

Helps prevent loss of control in curves and emergency steering maneuvers by stabilizing your car when it begins to veer off your intended path. What It Does: Works automatically to help the driver maintain control of the car during hard steering maneuvers.

When should ESC be turned off?

When operating the vehicle on a dynamometer, ensure that the ESC is turned off (ESC OFF light illuminated). If the ESC is left on, it may prevent the vehicle speed from increasing, and result in false diagnosis. Turning the ESC off does not affect ABS or brake system operation.

What are the benefits of ESC?

The efficiency of ESC is one of its most significant advantages. Without requiring human intervention, it applies brakes individually to each wheel. By preventing the car from skidding, it prevents serious accidents. It is also possible for a vehicle to roll over if it skids out of control.

Can my ESC handle 3s?

If your ESC is not rated for 3s, it will likely kill it as it will exceed the voltage limit. The current is a separate capacity and relates to the draw of the motor. Make sure you are 3s capable.

Does ESC affect motor speed?

An electronic speed control (ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking.

What is the rpm limit of the ESC?

It is a fixed limit. There is no relation between number of motor pole pairs and max ESC eRPM that will affect no load or max motor RPM. If you are using a motor with a maximum mechanical RPM of 9,000, and two pole pairs: (2 * 9000) = 18,000 eRPM, which is far less than the 350,000 eRPM limit of the Basic ESC.

Can a 60 amp ESC take 3S?

A quality 60A ESC will be fine on 3S...within reason, and as stated above with weight/motor kv concerns. Me, I'd just get a quality 120A ESC and be done with it. Key word italicized.
