Geared motor mainly refers to a gear motor assembled by a gearbox and a motor. The main function is to increase the torque and reduce the speed. It is widely used in many factories and is generally decelerated by means of a gearbox.

A geared motor refers to an integrated body of a reducer and a motor (motor), which is usually also called a gear motor or a gear motor. Usually by a professional reducer manufacturer, after being integrated and assembled, it is integrated with the motor. The gear motor is a power transmission mechanism. It is used in applications that require high torque and do not require too high rotational speed... For example: special equipment for automation... And with the development of industry and the automation of factories, the demand for the use of reducers is growing. There are usually many ways to reduce the speed, but the common method is to use gears to reduce the speed, which can reduce the occupied space and reduce the cost, so it is also called the gear box.

A variable speed machine is a rotary machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor, with current passing through its wires and receiving the 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 power frequency power supply (50Hz or 60Hz) into an AC power supply of various frequencies to realize the variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the alternating current into direct current. The circuit smoothes and filters the output of the rectifier circuit, and the inverter circuit reverses the direct current into alternating current. Frequency conversion speed regulation is to achieve the purpose of adjustment by changing the frequency of the motor stator winding power supply.
