FAQ: How To Run 2 Motors Off One Esc?

Can one ESC work on two motors?

Technically, you could connect 2 motors if they ‘re exactly the same and it will probably work. The problem with connecting more than one motor to a single ESC stems from how these motors are driven. An electric motor works by using electromagnetic coils to pull permanent magnets and create a force on the rotor.

Do you need an ESC for each motor?

Given that each brushless motor requires an ESC, a quadcopter will require 4 ESCs. The ESC takes the signal from the flight controller and power from the battery and makes the brushless motor spin. This is performed externally, through the use of an ESC.

Can I use any ESC with any motor?

Short answer is no. Not all brushless esc’s are compatible with all brushless motors.

How do I choose the right ESC for my motor?

The current rating of the ESC should be decided after selecting a suitable motor size. The maximum current draw of the motor at 100% throttle helps us to a select a suitable current rating. If a 2207 sized motor draws 40A at full throttle, these are at ground conditions.

How do you use ESC?

Manual ESC-by-ESC Calibration

  1. Plug one of your ESC three-wire cables into the throttle channel of the RC receiver.
  2. Turn on the transmitter and set throttle stick to maximum (full up).
  3. Connect the LiPo battery.
  4. You will hear a musical tone then two beeps.
  5. After the two beeps, lower the throttle stick to full down.

Can a bad ESC burn up a motor?

An ESC can keep ruining motors once it has been connected this way. The worst thing a brushless ESC can do is send DC directly into a three phase motor and then it will burn out. If the esc inadvertently glitched and went brushed on a brushless motor this is a bad thing.

Can you run a brushless motor without an ESC?

No, you can’t. A brushless DC motor is very similar to a three phase AC induction motor. You need to use a brushless DC motor controller (ESC) designed to generate the rotating field.

Do all brushless motors need ESC?

Actually most brushless motors in toys are brushless DC motors (BLDC) that don’t require the direction of current to alternate. and the ESC provides that for them. Yes.

Why did my ESC catch fire?

Simply Bad ESC Badly designed or over-rated ESCs are likely to catch fire. You probably don’t want to push the limit with these ESCs.

Will any ESC work with any receiver?

You need a brushless esc to work with a brushless motor but any esc can be connected to any receiver.

How do I connect my remote to my ESC?

Step 1: Be sure to fully charge both your board and your remote. Step 2: Turn on Your Board while keeping the remote off. Step 3: From the on position, Press and hold the power button of the ESC until the blue light begins to flash.

Does higher KV mean faster motor?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.

Can I use different ESC on quadcopter?

Can we use a different brand ESC in that quadcopter or multicopter? The answer is, it might work, but not recommended. However some flight controllers are smart enough to notice the unbalanced multicopter, and will give the under-powered ESC / motor higher power signal to balance it.
