Custom Frameless Motors

Customizable Stator & Rotor Options

Frameless motors are a fundamental element of today’s mechatronic systems, and classify both stators and rotors as separate components. If you have an extensive mechatronic assembly requirement that includes an electric motor, you might not need a fully-housed motor. US Motions provides frameless and custom-servo-motors, custom-housed motors, and custom servo motors that can be built to your specifications, which may include:

  • High Torque Capabilities
  • High Conductor Fill Factor
  • Specific Electrical Footprints Tailored to Application Requirements

US Motion engineers specialize in designing and manufacturing custom frameless motors with stator and rotor options.
