220V Motor AC Drive Mechanical Speed Controller for Blanking and Shearing Press
Certification:CE
220V Motor AC Drive Mechanical Speed Controller for Blanking and Shearing Press
Blanking machines cut, shear, or punch material during the process of fabricating a part. The material can be a flat sheet or a continuously fed strip of material. The main drive motor supplies power to a flywheel, which delivers the energy during the blanking/shearing stroke. AC drives are commonly used to provide power to the main drive motor.

Tips:
Avariable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
