Tips: The working Principle of Electromagnetic Brake Motor.
YEJ brake motor is also called an additional electromagnetic brake type three-phase AC asynchronous brake motor. How does the brake perform braking? Here is a brief introduction to the working principle of the YEJ brake motor brake:The YEJ additional electromagnetic brake motor consists of an ordinary three-phase asynchronous motor with an electromagnetic brake, which is installed on the non-working shaft extension end. The excitation current of the brake is generally direct current. According to different control requirements, it can be supplied by a separate direct current power supply or by introducing alternating current from the motor terminal, which will become a direct current power supply after rectification.Brakes can be divided into two types. One is to use the spring force of the brake to generate braking force on the motor rotor when the power is not applied. After the excitation coil is energized, the electromagnetic force will friction between the brake disc and the rotor shaft fixed on the rotor shaft. The disc is disengaged to eliminate the braking state, which is called power-off braking; the other is that there is no braking torque when the power is not applied, and the shaft can rotate freely, but after the excitation coil is energized, a braking force is generated and applied to the shaft Braking torque is called energized braking, and the former is more widely used.
