Product Short Description
Product Brief: Reliance Electric / Rockwell Automation light industrial brushless servo motor for high-precision motion control systems; discontinued original model.
Technical Specifications
- Rated Winding Voltage: 230 V AC
Description
- Pole Count: 8 poles
- Maximum Operating Speed: 4500 RPM
- Continuous Stall Torque: 2.5 N·m
- Peak Torque: 7.1 N·m
- Built-in Encoder: Optical encoder, 2000 P/R, 5 VDC power supply
- Enclosure Protection Class: IP43
- Max Radial Shaft Load: 35 kg
- Thermal Resistance: 0.85 °C/W
- Weight: 3.94 kg
- Brake Configuration: Without holding brake
Function Features
- Neodymium high-energy magnet rotor, low rotor inertia for fast acceleration and deceleration
- Integrated commutation & position feedback encoder
- Smooth speed regulation and high positioning accuracy
- Low torque ripple during continuous operation
Application Scenarios: Automated assembly machines, packaging machinery, material handling equipment, CNC auxiliary axes, robotic auxiliary joints
Material Composition: Aluminum alloy motor housing, silicon steel stator laminations, neodymium permanent magnet rotor, sealed ball bearings
Structural Features: Flange mounting structure, integrated encoder rear cover, separated power cable and encoder cable interfaces
Working Principle: Permanent magnet synchronous motor principle; servo driver outputs three-phase alternating current to generate rotating magnetic field, drives rotor rotation; encoder feeds real-time position and speed data back to servo drive for closed-loop control
Installation Requirements: Standard flange mounting; ensure coaxial connection with load; align coupling precision to avoid radial overload
Usage Notes
- Do not exceed specified maximum radial shaft load
- Keep ambient temperature within -10 °C ~ +40 °C
- Encoder wiring must use shielded cable to avoid signal interference
- Motor must be matched with corresponding Rockwell 1398 series servo drives
