Abstract: With the emergence of the energy crisis, more and more attention has been focused on energy saving. The energy saving technology of motor has also been widely concerned, because it is the main energy consumer. As the most potential energy saving technology, the variable frequency speed regulation has a good prospect of energy saving.
A variable frequency motor is a type of motor that is supplied with variable voltage/current and frequency. This enables variable speed control of 3-phased, standard asynchronous motors and permanent magnet motors. The adjustable frequency drive is capable of controlling either the speed or the torque on the motor shaft.
Variable Frequency Control of Multiple Synchronous Motors control not only allows the speed control, it can also be used for smooth starting and regenerative braking, as long as it is ensured that the changes in frequency are slow enough for rotor to track changes in synchronous speed. A motor with damper winding is used for pull-in to synchronism.
The energy saving technology of motor has also been widely concerned, because it is the main energy consumer. As the most potential energy saving technology, the variable frequency speed regulation has a good prospect of energy saving.
