Structural Features

1. Medium long stack frame design to maximize continuous torque output under fixed outer diameter size
2. Single-cable integrated wiring structure, power and feedback signals transmitted through one unified cable, reduces field wiring workload
3. Front double-bearing support structure, strong radial and axial load bearing capacity
4. Standard flange mounting form compatible with international IEC servo motor installation dimensional standards
5. Internal built-in winding temperature sensing thermistor for real-time overheating protection linkage with matched servo drive
6. Low cogging torque electromagnetic design, torque ripple controlled below 2% under full speed range operation
7. Rear encoder sealed independent cavity, isolated from motor internal winding heat to avoid high-temperature damage to precision feedback chip

Working Principle

1. Three-phase sinusoidal current output from matched servo drive flows into stator distributed winding, generates rotating alternating magnetic field inside motor housing
2. High-energy NdFeB permanent magnet fixed on rotor hub forms static fixed polarity magnetic field; interaction between stator rotating magnetic field and rotor permanent magnetic field generates continuous electromagnetic torque to drive output shaft rotation
3. Rear-mounted SFD3 absolute encoder collects real-time rotor absolute position signal, transmits digital position data to servo drive for triple closed-loop current-speed-position precise motion control
4. Winding built-in temperature thermistor feeds real-time temperature signal back to servo drive; drive automatically reduces output torque or triggers shutdown protection once winding temperature exceeds 155°C
5. Low cogging electromagnetic structure eliminates periodic torque fluctuation during low-speed rotation, realizes ultra-stable constant speed and positioning operation

Function Characteristics

1. High torque density long-stack structure outputs large continuous torque under limited installation radial space
2. 23-bit high-resolution absolute encoder realizes positioning repeat accuracy up to ±0.001°, zero homing requirement after power cycle
3. Single-cable wiring technology simplifies on-site wiring layout and reduces electromagnetic interference points
4. Wide constant torque speed range, maintains full rated torque output from 0 rpm to rated 3000 rpm without torque attenuation
5. Built-in winding temperature detection realizes real-time over-temperature linkage protection with matched servo drive
6. IP65 front shaft sealing adapts to equipment operating environment with light oil mist and splash water

Advantage Highlights

1. Medium long stack design provides 40% higher continuous torque than standard short-stack AKM62 base model
2. SFD3 single-cable absolute encoder eliminates separate feedback cable laying, reduces system wiring cost by half
3. Low cogging torque design guarantees smooth ultra-low-speed operation without obvious jitter below 10 rpm
4. Double-row front bearing structure bears large radial and axial external load without additional bearing supports
5. F-class high-temperature winding material supports long-time heavy-load continuous operation in high-temperature cabinet environment
6. Standard IEC flange size compatible with most automation equipment mechanical connection flanges, no custom mechanical modification required

Applicable Industries

Installation Requirements

1. Standard flange vertical or horizontal mounting allowed; maintain 50mm minimum clearance around motor housing for natural air convection heat dissipation
2. Motor output shaft and mechanical load coupling coaxiality tolerance ≤0.05mm; excessive eccentricity generates bearing wear and vibration
3. Single-cable servo wiring must use original Kollmorgen double-shielded dedicated single cable; cable bending radius ≥10 times cable outer diameter
4. Motor housing grounding terminal connected to equipment unified ground bar, grounding resistance ≤4Ω
5. Avoid blocking motor housing heat dissipation surface with mechanical brackets or cables; unobstructed airflow is mandatory
6. For heavy impact load application, install elastic damping coupling between motor shaft and load to absorb instantaneous shock torque

Usage Precautions

1. Strictly prohibit overload continuous operation exceeding rated 11.8N·m torque; long-term overload causes winding overheating and permanent magnet demagnetization
2. Do not operate above maximum mechanical speed 5000 rpm; over-speed centrifugal force risks permanent magnet detachment from rotor hub
3. Avoid direct impact collision to motor output shaft and rear encoder housing; impact damages bearing and precision encoder components
4. Regular semi-annual inspection of shaft front sealing ring; aging sealing ring causes oil mist and water vapor infiltration leading to internal winding short-circuit
5. Motor must match S400/S600/S700 series Kollmorgen servo drive with SFD3 decoding function; incompatible drive cannot read absolute position signal
6. Conduct annual bearing lubrication inspection; long-term high-speed operation consumes built-in bearing grease, generates abnormal vibration and noise
7. Do not operate under continuous condensation environment; water vapor infiltration destroys encoder internal circuit and winding insulation layer
