Motor Failure Example Answer

1.No way of knowing the RPM of the potentiometer.

Example：I received the motor, but when I took it out of the box, the potentiometer used to set the RPM spun freely without any end stops or any legs.Therefore, I have no way of knowing the RPM of the potentiometer.

Cause of Failure：

1）Do not rotate continuously, it will damage the end stops

2）The end stops have a weak cueing effect, so watch your strength when rotating them

3）Works fine without end stops and can be connected to battery to adjust speed
