Evaluation of a winding machine efficiency is effective or undesirable, moreover to operating characteristics (similar to torque, efficiency, power factor, and so forth.), the startup characteristics on the winding machine is also a vital indicator. Reliability Winder run depends to a large extent, start-up functionality is wonderful or terrible.

① beginning torque need to be sizeable enough to overcome the resistance of your winding machine and start torque;

② starting existing to be as small as you possibly can;

③ boot device need to be as straightforward, handy and economical, to operate.

Winder begin system can be divided into two types of direct begin and buck begins. Winder direct commence is straight connected towards the rated voltage begin, also known as complete pressure begin. This starting process is mainly put to use in massive power grid capacity, Winder beginning current will not cause substantial voltage drop within the power line occasion. Basic power 1Okw following Winder with complete pressure begin. In higher energy, the energy capacity will not be possible, really should buck starts. Buck began YA start strategy is often divided into law, compensation buck begins Law and Yanbian triangle buck starts many law. Precise approaches should be adopted as outlined by the motor nameplate and motor load carried by the situations.
