Totally enclosed DC motor in ultra slim pancake profiles. Incorporating flat armature technology, these pancake motors can provide a cost effective solution and servo capability ideal for high precision applications.

  • Low Profile
  • Zero Cogging
  • Rapid Acceleration
  • Low Inertia
  • Long Brush Life
  • Custom shafts, encoders, gearboxes and pulleys available

Pancake motors or printed armature motors and servodisc motors as they are also known, are employed for various industrial applications wherever rapid stop-start, zero cogging, low inductance, precise electronic motor control, a low thermal time constant or just a slim, axially flat packaging profile is needed.

Flat armature motors differ from conventional DC servomotors in their unique slotless disc armature design. This enables them to deliver a concentrated level of performance in both incremental motion and continuous speed that is not attainable with conventional iron-core motor designs.

The in-wheel XR series is a permanent magnet brushless motor with an external rotor. Permanent magnet brushless motors are generally the most efficient and highest torque density motors available today. The XR series gains from two distinct additional advantages: the magnets are positioned on an externally running rotor which gives the motor the fundamental geometric advantage that torque is being delivered on the outer-most point of the motor. Finally, the torque density of larger XR series is maximised by a high degree of slot fill. The high slot fill is achieved by winding each of the stator teeth individually before assembling them together into a stator.
