Electric machinery, commonly known as "motor", refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction.

Servo motors are widely used in various control systems. They can convert the input voltage signal into a mechanical output on the motor shaft and drag the controlled components to achieve the purpose of control.

In the application of micro DC motors, brushed motors and brushless DC motors each account for half of the country. The big difference between these two types of micro DC motors is that one has a brush and the other is brushless.

I use a time switch to control the motor. The switch burns after a while, I don’t know why? So how to control the motor with time switch? (Take 220V single-phase motor as an example)

The brushed DC motor uses mechanical commutation, the magnetic poles are not used, and the coil rotates. When the micro DC motor is working, the coil will drive the commutator to rotate.
