Generally, the variable frequency motor belongs to one of the three time asynchronous motors, because the three-phase asynchronous motor can be divided into variable frequency speed regulating motor, braking motor, variable frequency braking integrated motor and common motor according to its functional performance.
Compared with the reduction motor, the variable-frequency motor is only one of the motor parts. The motor of the reduction motor can not be the variable-frequency motor, such as other stepping motors and servo motors, while the reducer can choose many types. The variable frequency motor defines the motor as a variable frequency motor. Therefore, it is necessary to distinguish clearly the friends who are preparing to purchase reduction motor or frequency conversion motor.
Compared with the variable frequency motor, the reduction motor is more flexible because it is equipped with a reducer. For example, the rated speed of the motor is 1450 rpm and the rated torque is 10nm. Because it is equipped with a reducer, the speed ratio of the reducer is 1:100, so the final output speed of the reduction motor can be changed to 14.5 rpm, and the torque can be increased to 1000nm. Therefore, the capacity can meet the requirements of the transmission equipment in terms of speed and torque. However, the variable frequency motor has only rated speed and torque because there is no matching reducer. Therefore, it can not be more flexible applied to the equipment occasions with the requirements of changing speed and torque.
In fact, to understand the reducer from the definition refers to the combination of reducer and motor. It consists of two parts, one is motor, the other is reducer. The motor can be DC motor, AC motor, three-phase asynchronous motor, single-phase capacitor starting motor, stepping motor, servo motor, brushless motor, stepless variable speed motor, reversible motor, electromagnetic brake motor, variable frequency motor, etc. There are many kinds of reducers, such as gear reducer, worm and worm reducer, cycloid pin reducer, planetary reducer. It can be seen that the reduction motor is not equal to the variable-frequency motor, or it can be understood that the variable-frequency motor can be called the reduction motor, and the reduction motor is not necessarily the variable-frequency motor.
