Electric motor, also known as motor or electric motor, is an electrical device that converts electrical energy into mechanical energy, and then uses mechanical energy to generate kinetic energy to drive other devices. There are many types of motors, but they can be roughly divided into AC motors and DC motors for different occasions. The advantage of a DC motor is that it is relatively simple in speed control, and the speed can be controlled only by controlling the voltage, but this type of motor should not be operated in high temperature, flammable and other environments, and because the motor needs to use carbon brushes as The components of the current converter (Commutator) (with a brush motor), so it is necessary to regularly clean the dirt generated by the friction of the carbon brush. A brushless motor is called a brushless motor. Compared with a brush, a brushless motor saves electricity and is quieter because there is less friction between the carbon brush and the shaft. The production difficulty is higher and the price is higher. The AC motor can operate in high temperature, flammable and other environments, and does not need to clean the dirt of the carbon brush regularly, but it is more difficult to control the speed, because controlling the speed of the AC motor requires controlling the frequency of the alternating current (or using induction The motor, by increasing the internal resistance, reduces the speed of the motor at the same frequency of the alternating current), and controlling its voltage will only affect the torque of the motor. There are two types of voltages, such as 110V and 220V, in general civilian motors, and 380V or 440V in industrial applications.
