Just remove the motor screw at the end with the wire. {If you have a brush, be sure to remove the end with the wire, because the end without the wire has a commutator, and you can't knock out the motor. Both ends of the brushless motor can be removed, but to prevent the motor wire from being hit, the wired end is generally opened. Motors with gears are special, so be sure to pay attention. Some are opened at the wired side, and some are opened without wires. The end is open! } Turn on the motor three to four times. Don't knock it hard all at once, as the end cover of the motor may be easily broken! Generally, it will be difficult to open the motor if it has been exposed to water and is rusty. Knock it out slowly, and be sure to pay attention to the threads on the motor shaft head so as not to deform the screw threads.

Electric machinery (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque and serve as the power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert electrical energy into mechanical energy.
