DMZ1-□A series1 electromagnetic power-off brakeDetailed product description：

1. Introduction
The DMZ1- □ A series electromagnetic power-off brake is a friction brake that disengages (releases) when powered on and applies spring braking when powered off. It is mainly matched with Y series electric motors to form YEJ series electromagnetic braking three-phase asynchronous motors. Widely used in metallurgy, construction, chemical, food, machine tools, packaging and other machinery, as well as in situations such as emergency braking during power outages.

The DMZ1- □ A series electromagnetic power-off brake has the advantages of compact structure, easy installation, wide applicability, low noise, high working frequency, sensitive action, and reliable braking, making it an ideal automation actuator.
