A variable speed motor is a variable speed motor. Simply put, it is a rotary machine that converts electrical energy into mechanical energy. It mainly consists of an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. The current in the wire passes through and is rotated by the action of a magnetic field. Some of these machines can be used as electric motors or as generators.

The variable speed motor is a device that converts the commercial frequency power supply (50 Hz or 60 Hz) into an AC power source of various frequencies to realize the variable speed operation of the motor, wherein the control circuit completes the control of the main circuit, and the rectifier circuit converts the alternating current into direct current, and the middle of the direct current The circuit smoothes the output of the rectifier circuit, and the inverter circuit reverses the direct current into alternating current. For a frequency converter such as a vector control inverter that requires a large amount of calculations, sometimes a CPU for torque calculation and some corresponding circuits are required. The frequency conversion speed regulation achieves the purpose of speed regulation by changing the frequency of the power supply of the stator winding of the motor.

The geared motor is a combination of a reducer and a motor. It is a kind of power transmission mechanism that does not require too high a speed. The variable speed motor is a device that converts electrical energy into mechanical energy, which can convert the commercial power supply into an AC power source of various frequencies.
