制動器的勵磁線圈接通額定電壓（DC）時，電磁力吸合銜鐵，使銜鐵與制動盤脫離（釋放），這時傳動軸帶著制動盤正常運轉或啟動，當傳動系統分離或斷電時，制動器也同時斷電，此時彈簧施壓于銜鐵，迫使制動盤與銜鐵及法蘭盤之間產生摩擦力矩，使傳動軸快速停轉。在制動器散熱環境較差，傳動軸又是長時間連續工作時，如果條件允許，則可在制動器工作后，保持電壓轉換為70%-80%的額定電壓，以減少發熱。

 

Brake by magnetic yoke, excitation coils, springs, brake disks, armature, flower key sets, installation bolt etc., brake flange installed on the device (or motors) and back-end extension; shaft and spline sleeve and brake disc coupling. 

Brake connected to the excitation coil rated voltage (DC), the electromagnetic force pull-keeper, so that from the armature and the brake disc (released), when drive shaft with a brake disc or start normal operation, when the transmission separation or broken electricity when the brakes also power outages, this time put pressure on the armature spring force with the armature and the brake disc friction torque between the flange, so that shaft quick stop switch. In the brake thermal environment deteriorating, the shaft is Working long hours, if conditions permit, you can work the brakes to maintain voltage conversion is 70% -80% of the rated voltage in order to reduce fever.
