Thomson’s electromagnetic friction clutches and brakes provide efficient, electrically switchable operation between a motor and a load. Clutches link the motor to the load by coupling two parallel shafts through the use of pulleys, gears or sheaves. Power-on and Power-off (either spring-set or permanent magnet design) brakes provide an electrically switchable means of stopping and/or holding the load. While the field (electromagnet) assembly is fixed and prevented from rotating, the rotor (spring-set design) or armature (permanent magnet design) assembly is secured to the shaft.  For tooth clutches, couplings, and brakes, when the coil is energized the tooth profile of the armature positively engages the tooth profile of the rotor, coupling the two in-line or parallel shafts - thus driving the load.  These are perfect for either static or low speed engagement applications.
