How Does the Electromagnetic Brake Function in AC Gear Motors?
The electromagnetic brake functions in AC gear motors by using an electromagnet to create a braking force when needed. The main components involved are the electromagnet, brake disc, and the motor shaft. When electrical current flows through the electromagnet, it generates a magnetic field.
