Product Description

The Variable frequency Speed regulation Three phase Asynchronous Motors(VSD) are special three - phase asynchronous motors powered by variable - frequency speed - regulating devices. The system composed of these motors and the variable - frequency devices can achieve stepless speed regulation, thereby achieving the goals of energy conservation and automated control.
The VSD series motors feature a squirrel - cage structure and use special Class B and Class C anti - corona enameled wires. This effectively prevents inter - turn short - circuits in the windings caused by the peak voltage generated by the frequency converter, ensuring more reliable operation and convenient maintenance. The motors are equipped with independent axial - flow fans to ensure good cooling performance at different rotational speeds.
