The inverter uses the frequency to change the output speed, while the reducer and speed increaser use the number of gear teeth to change the output speed. Let me explain the difference in detail.
Difference between reducer and inverter: The reducer reduces the speed of the motor (motor) through a mechanical transmission device, and the inverter achieves the purpose of speed adjustment of the motor (motor) by changing the frequency of the alternating current. When the motor speed is reduced by the inverter, the purpose of energy saving can be achieved. There are three well-known inverter production companies in China such as Sanjing and INVT. The reducer is a relatively fine machine. The purpose of using it is to reduce the speed and add torque. It has many types and different types, and different types have different uses. There are various types of reducers, which can be divided into gear reducers, worm reducers and planetary gear reducers according to the type of transmission; they can be divided into single-stage and multi-stage reducers according to the number of transmission stages; they can be divided into cylindrical gears according to the gear shape Reducer, bevel gear reducer and conical-cylindrical gear reducer; according to the installation method of the transmission, it can be divided into expansion type, split type and coaxial type reducer.
Different types of speed reducers (motors) rotate speed, and the inverter is to adjust the frequency of the AC power to achieve the purpose of motor (motor) speed conditioning. When the motor speed is reduced by the inverter, the purpose of energy saving can be achieved.
