Function Features

1. Frameless split stator/rotor construction enables direct integration into machine spindle, rotary table and custom rotary actuator assemblies to reduce overall mechanical system volume
2. Ultra-high torque density rare-earth magnet rotor delivers fast start-stop dynamic response; full synchronous speed achieved within 5–25 millisecond cycle
3. Class H high-temperature winding insulation supports continuous heavy-duty operation without winding thermal degradation
4. Integrated resolver absolute position feedback eliminates position loss after power cycle, no homing routine required on equipment startup
5. Embedded PTC thermal sensor provides real-time winding temperature data to servo drive for over-temperature automatic torque derating protection
6. Low cogging torque stator lamination design minimizes vibration and positioning error at low operating speeds
7. Compatible with full Kollmorgen SERVOSTAR digital servo drive series for closed-loop speed, torque and position control modes

Working Principle

Material Composition & Structural Characteristics

• Stator Core: Stacked silicon electrical steel lamination sheets with surface insulation coating to reduce eddy current power loss
• Stator Winding: High-temperature Class H enameled copper magnet wire, vacuum-impregnated epoxy resin for vibration resistance and thermal conductivity improvement
• Rotor Assembly: Steel hub with press-fit neodymium permanent magnet segments secured by high-temperature epoxy adhesive
• Resolver Feedback Unit: Miniature brushless rotary resolver with stainless steel rotor shaft sleeve and epoxy-sealed stator coil
• Sealing Components: Fluorosilicone rubber O-rings for stator assembly dust and moisture sealing
• Termination Connectors: Shielded circular industrial aviation connectors for three-phase power wiring and feedback signal wiring

Installation Requirements

1. Mount stator assembly rigidly to machine housing via evenly distributed mounting bolt holes with torque 3.0 N·m
2. Rotor must be press-fitted onto customer machine precision shaft with controlled axial insertion force to avoid magnet demagnetization
3. Maintain uniform 0.3–0.5mm air gap between stator inner surface and rotor outer surface around full circumference
4. Separate power cable and feedback shielded cable routing by minimum 20cm distance; cable shielding connected to ground at both drive and motor ends
5. Avoid rotor assembly exposure to temperatures exceeding 180°C during mechanical bonding and assembly processes to prevent permanent magnet demagnetization
6. Install external forced air cooling fan if continuous operating duty cycle exceeds 80% to control winding temperature rise

Application Scenarios

• High-precision CNC machine tool direct-drive rotary spindles
• Industrial robotic joint rotary actuator integration
• Semiconductor wafer handling rotary positioning stages
• Packaging equipment high-speed rotary indexing tables
• Printing machinery precision register roller direct drive systems

Operation & Maintenance Precautions

1. Do not energize motor without properly installed rotor assembly; unloaded stator magnetic fields may cause permanent magnet demagnetization
2. Match motor rated voltage and current parameters strictly to paired Kollmorgen servo drive unit; parameter mismatch leads to winding burnout
3. Prevent metal magnetic debris accumulation inside stator air gap; magnetic particles cause rotor magnet surface abrasion and torque performance degradation
4. Annual inspection of resolver feedback cable shielding integrity; damaged shielding induces position signal noise and positioning inaccuracy
5. Do not perform welding operations near assembled motor unit without fully disconnecting power and feedback cables to avoid electrostatic magnet damage
