Motor

CM-AMB-400
Magnetic bearing motor CM-AMB-400
High-speed active magnetic bearing motor for direct drive of applications with highest speeds.

Operation in vacuum or special atmosphere
possible
Minimum volume thanks to integration of torque
generation and magnetic bearing in designed
space
Highest speeds for magnetic bearings thanks to
slotless winding technology
Stator winding and back iron configuration for
bearing forces without eddy current losses and
without reactive power demand up to highest
speeds
Custom specific modifications available
