Working Principle

1. Three-phase sine wave excitation current supplied by matched 230VAC low-voltage servo drive energizes stator long-stack distributed winding to generate stable high-strength rotating magnetic field;
2. Interior permanent magnet rotor interacts with stator rotating field to produce sustained high electromagnetic torque transmitted through reinforced T-series output shaft to mechanical load;
3. Rear-mounted analog resolver converts mechanical rotation angle and rotational velocity into analog voltage feedback signals, transmitted back to servo drive to form full closed-loop speed and position regulation;
4. Extended long stator stack design expands effective magnetic contact area to raise continuous torque output without enlarging flange installation footprint;
5. Reinforced front bearing and thickened shaft structure distributes heavy radial and axial mechanical loads evenly to eliminate local stress concentration during long-term heavy-load operation;
6. Vacuum-impregnated winding structure eliminates internal air gaps to reduce heat accumulation during full-load continuous duty cycle operation.

Function Features

1. Long-stack electromagnetic design delivers elevated continuous torque output ideal for low-speed steady rotation heavy-load axes;
2. T exclusive reinforced shaft and double front bearing assembly supports high radial load transmission modes including belt drives, rack pinion and large reduction gearboxes;
3. Analog resolver feedback maintains stable signal transmission under severe vibration, wide temperature fluctuation and oil mist industrial environments with zero signal attenuation;
4. Low cogging torque lamination layout restricts torque ripple <1.4% across the entire operating speed range to achieve ultra-smooth constant-speed operation;
5. Class F high-temperature winding enables stable continuous operation within ambient temperature range -20°C ~ +40°C;
6. Heavy-duty reinforced shaft oil seal extends service life under high linear velocity shaft friction conditions.

Advantage Highlights

1. Reinforced thickened output shaft and upgraded double front bearing assembly eliminate shaft bending and premature bearing failure risks for high radial load transmission systems;
2. Retains identical electrical performance parameters and mounting flange dimensions as standard B-406-AA-21 model, enabling direct mechanical upgrade for heavy-load retrofitting projects without equipment structural modification;
3. Thick aluminum alloy housing delivers excellent thermal conductivity to suppress winding temperature rise under long-duration full-load operation;
4. Vibration-resistant resolver feedback eliminates fragile optical encoder glass elements, eliminating failure risks in metal cutting and stamping workshop environments;
5. Full compatibility with all Kollmorgen CE06 low-voltage and AKD single/three-phase servo drives, no manual motor parameter calibration required after wiring connection;
6. Universal NEMA 34 flange mechanical interface supports direct drop-in replacement for all mainstream large-frame medium-torque servo motor brands globally.

Applicable Industries

Installation Requirements

1. NEMA 34 four-hole square flange mounting; M10 high-strength bolts crosswise evenly tightened to 18N·m torque to eliminate uneven flange mechanical stress;
2. Minimum clearance of 40mm surrounding motor heat sink fins to guarantee unobstructed natural convection airflow circulation;
3. Shaft coupling radial concentricity runout error strictly controlled ≤0.04mm; heavy-load rack and pinion transmission requires additional elastic buffer coupling;
4. Rear cable junction box must be positioned upward or horizontal orientation to prevent liquid coolant accumulation inside wiring terminal chamber;
5. Mounting base flatness tolerance ≤0.06mm over the complete flange contact surface; uneven base surface generates continuous side load on motor reinforced bearing assembly;
6. For belt-drive transmission systems, limit initial belt tension within manufacturer specified rated range to avoid excessive sustained radial load on T reinforced shaft.

Usage Precautions

1. Cease equipment operation for passive cooling if motor housing external surface temperature exceeds 90°C; maximum safe continuous winding operating temperature is 130°C;
2. Direct radial impact force cannot be applied to reinforced T output shaft during mechanical assembly; impact deformation of bearing inner race leads to irreversible bearing noise and wear;
3. Long-term continuous operation within mechanical resonance speed band of 900–1500 RPM is forbidden to avoid excessive vibration and structural fatigue of reinforced shaft assembly;
4. After reaching 20,000 continuous rated operating hours, bearing grease replenishment maintenance must be performed for front heavy-duty double bearing assembly;
5. High-pressure water jet direct washing of rear resolver feedback cover and power junction box is strictly prohibited to prevent water ingress damage to internal electrical components;
6. This motor model is exclusively matched with 230VAC low-voltage servo drives; connection to 380–480V high-voltage drives causes immediate irreversible stator winding insulation burnout;
7. Regular inspection of shaft keyway wear condition every 6 months for heavy cyclic load applications; replace coupling or shaft sleeve once keyway clearance exceeds design tolerance limit.
