Nema23 Brushless Dc Motor 57mm 3000rpm 0.6N.M Bldc Motor With Power On Break

Motor brakes are usually divided into power-off brakes and power-on brakes (electromagnetic power-off brakes or non-excitation action brakes). In short, the difference between the two is mainly whether the motor brake works when the power is on or off, and the choice of the motor brake is mainly determined according to the customer's use requirements.

The working principle of the motor energized brake: After the motor is energized, the magnetic coil inside the brake works, and the electromagnetic force attracts the brake pads. At this time, the brake pads release the brake disc, and the motor drive shaft drives the brake disc to run normally or start. When the current of the electromagnetic brake is cut off, the brake pads are separated from the brake disc, and the brake disc, the brake pads and the flange are run-in, and the running transmission shaft can stop quickly at this time.

The working principle of the power-off brake is: its structure is that the coil spring presses the brake pads, and the friction force of the brake pads is used to generate braking torque. When the brake disc is energized, the armature pressing the brake pad will compress the coil spring and be attracted by the excitation core, the brake will be released and the motor will run normally. If the excitation current is cut off, the pressure of the coil spring will cause the armature to press the brake pad. Under the action of the spring force, friction will be generated between the brake disc, the base and the armature, and then the transmission shaft will be braked through the gear sleeve. will move.
