Structural Features:
- Laminated silicon steel stator for reduced eddy current losses
- NdFeB (Neodymium) permanent magnet rotor
- Precision ball bearings (sealed, greased for life)
- Feedthrough connector for encoder (M23 or M12 connector)
- Optional shaft seal for IP67 environmental protection
Advantages:
- High torque-to-inertia ratio for fast acceleration
- Smooth sinusoidal torque with minimal cogging
- Integrated high-resolution encoder for precision feedback
- Robust construction for industrial environments
Applicable Industries:
- CNC machine tool axes
- Pick-and-place robots
- Semiconductor equipment
- Laser cutting and welding
- Print and packaging machines
Installation Requirements:
- Mount using 4x M5 mounting holes on 80 mm bolt circle
- Maximum shaft overhung load: 50 N radial, 20 N axial
- Coupling alignment tolerance: <0.05 mm TIR, <0.05° angular misalignment
- Ensure proper grounding of motor frame and drive chassis
Usage Notes:
- Do not operate without a servo drive; this motor requires a sinusoidal commutating drive
- Maximum ambient temperature for continuous operation: 40°C (derate torque above 40°C)
- Bearing life: L10 > 20,000 hours at rated speed and load
