Product Introduction:
The CE03560 is a frameless brushless DC torque motor engineered for direct-drive rotary motion applications. It features an outer-rotor construction with no mechanical housing, allowing seamless integration into the customer’s mechanical structure. This motor eliminates the need for gearboxes, couplings, and belts, thereby reducing backlash, improving system stiffness, and minimizing maintenance requirements.

Structural Features:
- Outer-rotor, inner-stator topology — the rotor is a cylindrical shell that mounts directly to the load
- No bearings, no shaft, no housing — fully frameless design
- High-energy rare-earth magnets (NdFeB) embedded in the rotor
- Epoxy-potted stator windings for environmental protection
- Pre-installed Hall sensors for commutation feedback
Functional Features:
- Provides smooth, cog-free torque output
- Zero-backlash direct-drive capability
- High torque density at compact form factor
- Suitable for continuous and intermittent duty cycles
Applicable Industries:
- Semiconductor wafer handling
- Robotic joint actuation
- Gimbal and stabilizer systems
- Medical imaging (CT, MRI gantries)
- Aerospace actuators
- Optical scanning and positioning
Installation Requirements:
- Motor must be press-fit or bonded into a custom mechanical housing
- Bore tolerance: H7 (±0.015 mm)
- Mounting flange or clamp must support radial and axial loads
- Thermal path from stator to external heat sink is mandatory for continuous operation
Usage Notes:
- Do not operate without a proper thermal management system under continuous load
- Hall sensor wiring must follow Kollmorgen pinout specification (Red = Vcc, Black = GND, Green/Yellow/Blue = Hall A/B/C)
- Maximum operating temperature: 155°C (winding insulation class H)
