Armature reaction refers to the effect of armature magnetic potential on the magnetic density distribution of air gap. So what is the central response of the brake motor in no-load and load? Here is a simple understanding with Senli Motor Xiaobian.

        Brake motorIn no-load operation, the air gap density generated by the excitation potential alone is a flat-top wave. When the load is running, the armature winding flows through the armature current to generate the armature magnetic potential, and the air gap synthesis magnetic density is established together with the excitation magnetic potential, which will inevitably change the distribution of the original air gap magnetic density.

        Armature magnetic potential if acting alone, atBrake motorThe armature magnetic field generated in the air gap, and then the armature magnetic field and no-load air gap magnetic field can be combined to get the load magnetic field, and compared with the no-load air gap magnetic field, so that we can understand the impact of the armature reaction of the brake motor.
