Fractional HP Clutches/Brakes
Warner Electric clutches and brakes are designed to start and stop inertial loads when the voltage is turned on. When DC voltage is applied to the coil, the magnetic force caused by the magnetic flux pulls the armature across the air gap against the force of the zero-backlash spring attached to the armature. The mating of the armature and rotor face transmit torque.
When DC voltage is interrupted, the magnetic field collapses, and the zerobacklash spring retracts the armature from the rotor face. There is no residual torque produced.
SFPB SeriesSFPB Series provides a clutch (SF) and brake (PB) combination for use with pulley or sprocket input. The clutch and brake are mounted back-to-back with a torque arm to provide for simplicity of mounting.
SFPBC SeriesSFPBC Series provides a clutch coupling (SFC) and brake (PB) combination for coupling two in-line shafts. The clutch coupling and brake are mounted back-to-back with a torque arm to provide for simplicity of mounting.
