These incorporate internal electromagnetic-actuated brakes and compact power supplies without changing the dimensions of the general-purpose motor.As electromagnetic-actuated brakes, these models brake motor shafts when current runs through the brake coil. Shutoff of the current to the brake coil instantly releases the brake. Brake torque is transmitted using a constant-load disc spring, so braking is always reliable.
