DMZ1 series electromagnetic power-off brakeDetailed product description：

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