Description

Technical Specifications: Frame Size: 065; Motor Length: D; Nominal Speed: 4000 rpm; Continuous Standstill Torque: 2.7 Nm; Peak Torque: 10.8 Nm; Continuous Current: 6.3 A; Peak Current: 28.5 A; Winding Type: N2L; Holding Brake: 3.0 Nm holding torque; Centering Diameter: 95 mm; Shaft: Keyway per DIN 6885; Weight: 5.3 kg; Feedback: Digital Servo Feedback (DSF)

Function Features: High torque density design; low rotor inertia for high dynamic response; integrated digital encoder feedback; built-in electromagnetic holding brake; IP65 shaft seal protection; high overload capability

Application Scenarios: CNC machine tool feed axes, laser cutting machines, industrial robotic arms, packaging machinery, printing equipment, automated assembly systems

Performance Parameters: Torque constant: 0.43 Nm/A; rotor moment of inertia: 0.00081 kgm²; thermal time constant: 12 minutes; speed accuracy ±0.01% of setpoint

Material Composition: High-strength aluminum alloy housing, rare-earth permanent magnet rotor, copper stator winding, high-precision ball bearings, steel output shaft

Structural Features: Flange mounting design; keyed output shaft; rear-mounted integrated encoder; side-mounted electrical connector; integrated holding brake assembly; shaft seal for contamination protection

Working Principle: Three-phase stator winding generates rotating magnetic field when supplied with variable frequency AC current; drives permanent magnet rotor to rotate synchronously; digital encoder feeds back rotor position and speed to servo drive for closed-loop control; holding brake engages when power is removed to lock load position

Installation Requirements: Mount via flange in vertical or horizontal orientation; align coupling concentricity to minimize radial load; protect shaft from impact and side loads; use shielded cables for power and encoder connections

Usage Notes: Verify brake release voltage and current before operation; avoid continuous operation above maximum rated speed; monitor bearing temperature and vibration during operation; protect encoder cable from excessive bending and mechanical stress
