Briefly describe the difference between geared motors and speed changers
The geared motor refers to the integrated body of the reducer and the motor (motor). This integrated body is usually also called a gear motor or a gear motor. Usually a professional reducer manufacturer will integrate and assemble it with the motor as a complete set of equipment. The reducer motor is a power transmission mechanism. It is used in applications that require high torque and do not require too high speed. . For example: special equipment for automation... And with the development of industry and the automation of factories, the demand for reducers is increasing. There are usually many ways to reduce speed, but the commonly used method is to reduce the speed by gears, which can reduce the occupied space and reduce costs. Therefore, some people call the geared motor a 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 to generate a magnetic field, and a rotating armature or rotor. The wire has current passing through and is subjected to the magnetic field. Some types of these machines can be used as electric motors and generators. Variable-speed motor is a device that converts industrial frequency power (50Hz or 60Hz) into AC power of various frequencies to realize variable-speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts AC power into DC power. 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.
