  • Disc Motors
    bonded to a rigid insulating disc. Since no iron is needed in the disc armature, it has a very low inertia. The thin armature design provides a high torque-to-inertia ratio. High ratios produce accelerations from 0 to 3,000 rpm in only 60 of rotation. Conventional motors also produce cogging when
  • Coreless DC Motors
    in conventional motors is caused primarily by the release of stored energy in the armature inductance upon commutation. Excessive arcing produces electrical noise and reduces the life of brushes. Coreless motors are classified by rotor shapes as cylindrical or disc. Cylindrical rotors are further divided
  • Limited-Angle Torque Motors
    for heat-seeking sensors, and power other systems that rotate through small angles. The rotor in a limited-angle torquer carries field magnets, and the stator supports armature windings (similar to the construction of conventional brushless motors). LATs, however, are wound single phase, unlike conventional
  • Electric clutches on the go
    . The rotor assembly includes the pulley and bearing and is normally the point of input to the clutch. The armature assembly includes the armature disc, springs, and hub and is normally the output. The field assembly mounts to a stationary member such as a pump support bracket. The rotor, driven
