Structural Characteristics

1. Square IEC standard mounting flange with four symmetrical M8 threaded mounting holes for universal mechanical fixture compatibility
2. Integrated rear housing embedded M23 12-pin combined power/encoder single connector interface
3. Double bearing front-rear support shaft structure limits radial and axial shaft play within ≤ 0.01 mm
4. Internal stator winding fully vacuum impregnated epoxy resin for vibration resistance and moisture insulation
5. Separate sealed encoder rear cavity isolated from motor stator heat zone to maintain encoder operating temperature stability

Working Principle

1. AKD servo drive outputs three-phase sine wave alternating current to motor stator distributed windings to generate rotating electromagnetic magnetic field
2. Rotor surface-mounted rare earth permanent magnet generates fixed magnetic field; stator rotating magnetic field pulls rotor synchronous rotation at equal electrical frequency
3. BiSS C absolute encoder mounted on motor rear shaft continuously samples rotor mechanical angular position and transmits digital position signal to servo drive feedback port
4. PTC thermal sensor embedded within stator windings sends temperature resistance signal to drive for real-time winding temperature monitoring; drive reduces output power or triggers fault lockout upon overtemperature threshold crossing
5. Six-pole electromagnetic layout optimizes magnetic field waveform to suppress torque ripple and cogging effect during full speed range rotation

Advantage Highlights

1. Standard IEC mounting flange compatible with global mechanical design standards, no custom fixture modification required for equipment integration
2. Multi-turn absolute encoder eliminates machine homing cycle after emergency power failure, improving production equipment operating efficiency
3. IP65 full environmental protection grade allows direct installation on machine processing zones exposed to cutting fluid splash
4. Single combined connector design reduces machine wiring layout complexity and cable material cost
5. Full series cross-compatibility with all AKD-P high voltage servo drive models without parameter limitation

Applicable Industries

Installation Requirements

1. Mounting flange surface flatness tolerance ≤ 0.02 mm; uneven mounting surface generates excessive bearing radial load
2. Shaft coupling radial misalignment limited to ≤ 0.01 mm; flexible bellows coupling mandatory, rigid coupling prohibited
3. M8 mounting screw tightening torque controlled at 12 N·m; over-tightening deforms aluminum mounting flange
4. M23 connector cable assembly must maintain minimum 150 mm free bend length at motor rear housing to avoid cable weight bearing on connector housing
5. Motor installation orientation unrestricted; horizontal, vertical shaft up/vertical shaft down installation all permitted under IP65 protection

Operation & Maintenance Precautions

1. Do not apply hammer impact force directly to motor output shaft during coupling installation; impact damages internal bearing and encoder assembly
2. Ambient air must remain clean without conductive metal dust; metal dust ingress causes stator winding short-circuit failure
3. Avoid continuous operation above 40 °C ambient temperature without optional cooling fan; long-term high temperature accelerates magnet demagnetization
4. Lubricate motor bearings every 10,000 operating hours with Kollmorgen certified high-temperature bearing grease
5. Disconnect all power supply before removing M23 connector; hot plug operation damages encoder communication circuit permanently
