206.5 Nm continuous at 1,800 RPM · 590 Nm peak · 360 frame · surface-magnet rotor
The 360-AZZS72-550 is a 37.0 kW permanent magnet synchronous motor for a 72 V bus, rated 206.5 Nm at 1,800 RPM continuous. It holds 80.0 kW and 404.8 Nm for 15 minutes, and peaks at 116.5 kW. It weighs 81 Kg and mounts flange, foot.
The rotor is surface-magnet, which gives the higher torque per amp of the two rotor types and a simpler thermal picture under sustained load. Suited to hydraulic power units, traction drives and pump packages, where a single reduction stage is normal.
Ratings are published at three duty points rather than one headline figure. Size the motor so its continuous rating covers the average of the duty cycle and its 15-minute rating covers the worst peak — the full 72 V range has 63 models if this one sits slightly wrong.
Quality and compliance
Manufactured at our ISO 9001:2015 certified plant in Faridabad, India. Designed and tested to IEC 60034 — performance and rating to IEC 60034-1, IP64 enclosure to IEC 60034-5, mounting designations to IEC 60034-7, and Class H insulation to IEC 60085.
Every motor is individually tested before dispatch, not batch-sampled: winding resistance, insulation resistance, high-voltage withstand, back-EMF constant, no-load and loaded run, and temperature rise. Test reports are available on request.
Performance Curves
Where this motor is used
- Hydraulic power units on 72 V mobile and industrial equipment
- Traction drives through a single reduction stage
- Pump packages where continuous duty matters more than peak speed
- Compressors and industrial fans in the mid speed range
