Readers ask: Motors Spin When Armed?

Why do my motors keep accelerating on the bench when I arm without props?

What you’re seeing as the motors slowly spin-up is the buildup of that Ki value getting stronger and stronger as flight controller is trying harder and harder to execute a change that it can sense, but can’t impact. No props means no force to execute change, hence the windup.

How do you spin a motor in Betaflight?

Using the Motor Tab in Betaflight Enable the checkbox “I understand…”, and increase the slider just a tiny bit (e.g. 1100) to spin up the motor. Don’t drag the slider all the way up, spinning the motor at full speed without propeller for too long can damage the motor.

Do all motors spin in the same direction?

Electric motors are designed either for clockwise rotation, or counter-clockwise, or both. If you swap a pair of the phases, it shall rotate counter-clockwise. Still everything is very simple. However, surprisingly quite often it happens that the motor is ordered with the wrong direction of rotation.

Why does my drone keep spinning?

If your quadcopter is still spinning uncontrollably, your drone’s ESC may be the culprit. The ESC, or electronic speed controller, connects your drone’s flight controller to the motor. Simple enough but with four or more motors to spin, that means four or more different ESCs that need to be working in sync.

Should a brushless motor spin freely?

A brushless motor should spin freely when all the wires are separated as there is not a complete circuit. If the motor resists your rotation regardless of the wire connections, it’s likely that your motor has an internal short circuit.

Why is my brushless motor not spinning?

The way a brushless motor works is by using electromagnets, rather than brushes, to spin the motor. If any two of the wires are shorted together, you will experience resistance if you try to spin the motor by hand. If you separate all the wires, the motor should have no problem spinning when hand-propelled.

Why won’t my motors spin in Betaflight?

Answer: Hold both of the joysticks in the down position and then flip the arm toggle (SwA in my set up) to the down all at the same time.

How can a motor spin fast?

One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.

How do you tell if a motor is clockwise or counterclockwise?

You can determine shaft end perspective by simply holding your motor up in front of you and pointing the shaft at you. If the shaft is pointing at you and rotates to the right, your motor is clockwise shaft end, or CWSE. If the shaft rotates to the left, your motor is counterclockwise shaft end, or CCWSE.

Can you reverse the rotation of electric motor?

Motor rotation is essentially created by the manipulation of wires and magnetic fields. Thus, you can often reverse AC motors by switching the wire connections. This is as easy as unhooking and re-crimping the designated wires.
