YEJElectromagnetic brake motor is also called additional electromagnetic brake typeThree-phase AC asynchronous brake motorSo how does the brake brake? The following mori force motor small make upYEJThe working principle of electromagnetic brake motor brake is briefly introduced:

       YEJAn additional electromagnetic brake motor consists of an ordinary three-phase asynchronous motor with an electromagnetic brake, which is mounted on the extension end of the non-working shaft. The excitation current of the brake is generally direct current, which can be supplied by a separate DC power supply according to different control requirements, or AC power can be introduced from the motor terminal and become DC power supply after rectification.

       The brake can be divided into two kinds, one is in the case of no power, the use of brake spring force to generate braking force on the motor rotor, the excitation coil is energized, the electromagnetic force will be the brake disc and fixed on the rotor shaft friction plate off, eliminate the braking state, called power off braking; The other is that there is no braking torque when there is no power, the rotating shaft can rotate freely, but after the excitation coil is energized, the braking force is generated, and the braking torque is applied to the rotating shaft, which is called energized braking, the former is more widely used.
