Frameless Custom Servo Motors Built to Your Requirements
Frameless Motors are a fundamental element of today’s mechatronic systems, and include both Stator and Rotor as separate components.
If you have an extensive mechatronic assembly requirement that includes an electric motor, you may NOT need a fully housed motor.
We provide frameless custom servo motors 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.
STATOR Options:
- Slotted or slotless construction
- Welded or bonded laminations
- Powder coated or Nomex stator insulation
- Skewed or straight
- Conventional wound conductor or multilayer PCB stators
ROTOR Options:
- Surface Permanent Magnet (SPM) and Internal Permanent Magnet (IPM) Rotors
- Permanent Magnet Materials & Grades:
- Neodymiium
- Samarium Cobalt
- Alnico
- Others
- Skewed or Straight Magnets
- Non-Permanent Magnet type
- Squirrel Cage/Induction
- Switched Reluctance
- Laminated or Solid Core
- Radial Flux or Axial
