Conical rotor motor, the rotor is conical, and the brake is integrated with the motor. When the motor is not working, the tapered brake will hold the rear end cover of the motor in a braking state; when the motor stator is energized, it will generate axial magnetic pull while generating rotational torque, so that the rotor moves axially and compresses the brake Spring, when the brake wheel is released, the rotor starts to run; when the motor is powered off, the axial magnetic pull disappears, the brake wheel generates braking torque under the action of the brake spring, and the motor can stop working in time.
