Working Principle

1. Three-phase high-frequency sine wave current output from matched high-voltage servo drive energizes stator distributed winding to generate rotating electromagnetic field;
2. High-energy permanent magnet rotor interacts with stator rotating field to produce stable continuous high electromagnetic torque on motor output shaft;
3. Rear-mounted resolver feedback sensor converts mechanical rotation angle and speed into analog voltage signal, transmitted back to servo drive for full closed-loop position/speed control;
4. Vacuum-impregnated stator winding eliminates internal air gaps to minimize winding temperature rise under continuous full torque load;
5. High-coercivity rotor magnet maintains magnetic flux stability under continuous high-temperature operation without irreversible demagnetization.

Function Features

1. Ultra-high torque density large frame IPM electromagnetic design, torque ripple <1.5% at full operating speed range for uniform heavy load rotation;
2. Class F reinforced winding supports continuous stable operation in ambient temperature range -20°C ~ +45°C;
3. Resolver feedback immune to heavy vibration, cutting oil mist, and wide temperature fluctuation with zero signal attenuation;
4. IP65 full housing protection allows direct installation inside metal cutting machine tool coolant splash zones;
5. Heavy-duty double roller bearing service life reaches 30,000 operating hours under rated continuous torque load.

Advantage Highlights

1. 62N·m continuous stall torque eliminates need for external reduction gearbox in many medium heavy-load low-speed applications;
2. Large-area aluminum heat sink maintains low winding temperature rise even under 100% continuous full-load duty cycle;
3. IEC standard flange mechanical interface compatible with global industrial gearbox and load coupling brands;
4. Perfect plug-and-play parameter matching with Kollmorgen S700, CE06200 high-power three-phase servo drives;
5. Vibration-resistant resolver feedback eliminates optical encoder glass component failure risk for heavy metal processing equipment environments.

Applicable Industries

Installation Requirements

1. IEC standard four-hole flange mounting, M12 high-strength mounting bolts evenly cross-tightened with 45N·m torque;
2. Minimum 60mm clearance around motor housing heat sink fins for unobstructed natural convection air flow;
3. Shaft coupling radial concentricity runout error limited ≤0.04mm to avoid accelerated bearing fatigue failure;
4. Motor junction box must be positioned upward or horizontal orientation to prevent coolant liquid accumulation inside terminal chamber;
5. Mounting base flatness tolerance ≤0.08mm across full flange contact surface to eliminate uneven flange stress;
6. Mandatory use of high-torque flexible bellows coupling, rigid direct shaft connection prohibited for heavy reciprocating load axes.

Usage Precautions

1. Stop equipment cooling operation immediately if motor housing surface temperature exceeds 95°C, maximum allowable winding temperature 150°C continuous;
2. Prohibit direct radial impact force on output shaft during mechanical assembly to prevent bearing race permanent deformation;
3. Avoid long-term continuous operation within motor mechanical resonance speed band (800–1200 RPM);
4. Bearing grease replenishment maintenance required after 30,000 continuous operating hours of full rated torque load;
5. High-pressure coolant jet washing of rear resolver feedback cover and terminal junction box strictly forbidden;
6. Only operate matched with 380–480VAC three-phase high-voltage servo drives, incompatible with low-voltage 230V drive output without winding burnout risk.
