Frameless motor part set design from BEI Kimco allows for the motor to be fully integrated within the customer assembly resulting in the highest ratio of torque to volume. In this configuration the motor’s rotor and stator are housed within the customer’s “next higher” assembly utilizing a common shaft and bearing system. This results in increased coupling efficiencies, reduced system size, weight and cost.


  • Highest energy product permanent magnet rotor design for improved efficiency
  • High pole count rotor for smooth operation
  • Proprietary magnetic circuit design for optimal efficiency
  • Low torque ripple
  • Encapsulated Stator assemblies for improved thermal performance
