Structural Characteristics

1. Compact 70 mm square front flange mounting layout with four symmetrical fixing bolt holes for miniature automation fixture installation
2. Full radial external cooling fin housing for passive natural convection heat dissipation during continuous high-speed operation

5. Front double-lip fluorine rubber shaft sealing ring installed at shaft output end to upgrade environmental protection performance
6. Standard smooth solid output shaft compatible with clamp-type elastic couplings and timing belt pulleys

Working Principle

1. AKD series high-voltage servo drive outputs three-phase sinusoidal variable-frequency AC current to motor stator winding coils
2. Rotating electromagnetic field generated by stator windings interacts with rotor embedded NdFeB permanent magnet ring to produce continuous high-dynamic rotational torque output
3. Rear-mounted 23-bit EnDat 2.2 absolute encoder captures real-time rotor absolute angular position and rotational velocity digital data, transmits signal back to matched AKD servo drive
4. Servo drive executes torque, velocity and position triple closed-loop control algorithms using encoder feedback data to achieve ultra-precise rapid dynamic positioning control
5. When 24VDC brake release power supply is disconnected, built-in compression spring pushes brake friction disc to lock output shaft; energized brake coil pulls friction disc away to release free motor rotation

2. 23-bit absolute EnDat encoder eliminates machine homing steps after power restart, reducing production line downtime
3. Integrated spring holding brake maintains static positioning accuracy without continuous power draw, cutting standby energy consumption
4. IP65 full housing + IP67 front shaft sealing adapts to light coolant mist and dusty workshop production environments
5. Single combined power/encoder cable connector reduces wiring material cost and installation labor time
6. Native plug-and-play compatibility with all AKD-P 480VAC high-voltage servo drives for automatic motor parameter identification and one-click load auto-tuning

Applicable Industries

Installation Requirements

1. Mount motor via full-surface contact of 70 mm square front flange with rigid miniature metal fixture, evenly tighten four fixing bolts to specified torque value
2. Install lightweight elastic clamp coupling between motor output shaft and mechanical load to absorb high-speed acceleration shock and eliminate radial bearing overload stress
3. Reserve minimum 40 mm rear clearance for encoder and brake wiring harness routing and heat dissipation airflow circulation
4. Use original Kollmorgen single combined shielded servo cable for power and encoder signal transmission with single-point shield grounding at cabinet earth bar
5. Avoid mounting motor in direct coolant spray zones; install external lightweight plastic splash guard if operating near cutting fluid sources
6. Ensure mounting fixture structural rigidity; thin flexible mounting plates induce resonance during 6000–8000 RPM high-speed operation

Usage Precautions

1. Limit continuous 300% peak overload operation duration strictly under 8 seconds; prolonged high overload causes permanent demagnetization of rotor NdFeB rare-earth magnets
2. Do not disassemble rear encoder housing on-site; factory calibrated encoder zero position data is lost after disassembly, requiring factory recalibration
3. Clean motor housing cooling fin dust accumulation every 3 months in metal processing workshops to prevent chip blockage of heat dissipation airflow
4. Deploy forced air auxiliary cooling fan for continuous full-load operation at ambient temperature above 40°C with 10% continuous torque output derate
5. Avoid axial impact shock to motor output shaft; impact force damages rear internal EnDat encoder optical components
6. Disconnect matched AKD drive three-phase power supply before plugging/unplugging motor combined connector to prevent electric arc damage to contact pins
