Description

Technical Field

[0001] The utility model relates to the field of electromagnetic brakes, in particular to a bidirectional thrust electromagnetic brake. Background Art

[0002] Electromagnetic brakes use electromagnetic effects to achieve braking. They are an ideal automated actuator in modern industry. In mechanical transmission systems, they mainly play the role of transmitting power and controlling motion. They have the advantages of compact structure, simple operation, sensitive response, long life, reliable use, and easy remote control.
