Introduction to electromagnetic brake
The electromagnetic power-off brake is a friction brake (hereinafter referred to as brake) with power on, release and power-off spring braking. It is mainly matched with Y series motor to form YEJ series electromagnetic braking three-phase asynchronous motor. It is widely used in metallurgy, construction, chemical industry, food, machine tools, packaging and other machinery, as well as in power-off safety braking and other occasions to realize rapid parking and accurate positioning. The brake has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action and reliable braking. It can be attached with a manual release device. It is an ideal automatic control actuator. It is divided into torque adjustable type (conventional type) and non adjustable type .
Order must see
1,For the matching of the motor, the power of the matching motor and the torque reached by the brake shall be provided.
2,For the transformation of old equipment, it is necessary to provide the equipment operation and the root cause of equipment failure.
3,Choose the right products. If due to space constraints, our company can help you customize products with special specifications to meet your needs.

The DZSJ7 series AC electromagnetic power-off brake is a friction type brake that is powered off (released) and powered off by a spring brake. It is mainly matched with Y series motors to form YEJ series electromagnetic braking three-phase asynchronous motors. Widely used in metallurgy, construction, chemical industry, food, machine tools, printing, packaging and other machinery, as well as braking in the event of power failure (risk prevention). This type of brake has the advantages of compact structure, wide applicability, high working frequency, sensitive action, reliable braking, convenient installation and wiring, impermanent rectifier, and faster braking time than DC brake. It is an ideal automation execution component.
