88.8 Nm continuous at 2,400 RPM · 254.6 Nm peak · 360 frame · surface-magnet rotor

The 360-DZS72-300 is a 22.0 kW permanent magnet synchronous motor for a 72 V bus, rated 88.8 Nm at 2,400 RPM continuous. It holds 44.6 kW and 175.7 Nm for 15 minutes, and peaks at 64.7 kW. It weighs 54 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.
