Our large supply of 0.5-32 hoist brake, the product is easy to install, extremely resistant, versatility. Special motors, induction motors are self-braking. There beside the magnetic structure, leveraged, conical rotor type three, I just say the last brake principle of it. Conical rotor motor stator and rotor cavity are tapered shape, its conical brake ring embedded in the fan wheel brake, inaction ring set in the end cap, after the stator is energized to produce a rotating magnetic field, generating Axial magnetic pull, axial movement of the rotor and a compression spring, the tapered ring fan brake wheel and inaction on the left ring rotor began to turn after the stator power, axial magnetic tension disappears, the rotor in the spring Under the action, along with the fan wheel brake reset together to make contact with the brake ring movement, friction torque, forcing the motor stopped immediately. Generally there is no such single-phase motor.
