Dc inverter braking principle

Set the starting frequency of dc brake and dc brake voltage, should follow the following principles: 3.1 driving system, make sure you are able to eliminate "crawling" phenomenon; 3.2, dc braking motor spare parts current should not exceed the rated current of inverter; 3.3, in the process of the brake system without strong vibration; Dc brake applied occasion. Dc brake is suitable for motor electric the power of 50-100 - kw three-phase asynchronous motor. 4.1 no www.facebook.com/dongfeng.motor impact on the smooth, requirements, parking accurate, such as knitting, sewing, crane, 3 phase ac induction motor hoist, etc; 4.2, before starting brake motor, eliminate irregular rotation caused by external factors, such as a large fan, etc.
