Inverters use a change in frequency to achieve the need to change the output speed, while gearboxes and speed boosters use the number of teeth in the gears to change the output speed, and I'll talk about what the specific differences are.
Difference between speed reducer and frequency converter: speed reducer is to reduce the speed of motor (motor) through mechanical transmission device, while frequency converter is to change the frequency of alternating current to reach the intention of motor (motor) speed regulation. When the frequency converter reduces the speed of the motor, it can achieve the intention of energy saving. Comparison of domestic famous frequency converter production company has three crystal, YingWeiTeng and so on. Reducer is a relatively delicate machinery, the intention of using it is to reduce the speed and increase the torque. Its varieties are complex, different types, different varieties have different uses. Reducer varieties complex, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; according to the number of transmission stages can be divided into single-stage and multi-stage reducer; according to the shape of the gear can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear reducer; in accordance with the placement of transmission can be divided into the unfolding, shunt type and with the In accordance with the transmission placement can be divided into expansion type, shunt type and coaxial type reducer.
Different varieties of speed reducer (motor) speed, and the frequency converter is to change the frequency of the alternating current to achieve the intention of motor (motor) speed regulation. When the speed of the motor is reduced by the frequency converter, the intention of energy saving can be achieved.
