Description
Connect it in star to a 400 V three-phase supply, or in delta to 230 V. The flange (Ø 160 mm, pitch circle 130 mm, spigot 110 mm, 4 holes Ø 10 mm) mounts it directly on a pump carrier or gearbox. Shaft Ø 14 mm, 30 mm long, with keyway. Ambient temperature -15 to +40 °C.
Pros:
- Runs on 400 V (star) or 230 V (delta) three-phase supply
- Flange mounts directly on a pump carrier or gearbox
- Standard IEC frame 71 dimensions - replaces other IEC motors of the same size
- Lightweight aluminium housing
Cons:
- For lower speed and higher torque, choose the 4-pole (1500 rpm) motor
- Ambient temperature up to 40 °C only
Series:
EMO three-phase asynchronous motors with aluminium housing, surface-cooled, IP55, insulation class F and duty S1 for continuous operation, with the terminal box on top. 4-pole motors run at about 1500 rpm and 2-pole motors at about 3000 rpm at 50 Hz, in IEC frame sizes with standard shaft and flange dimensions. Up to 1.5 kW the winding is for 230/400 V (delta/star), from 2.2 kW for 400/690 V, so every motor runs on a 400 V three-phase supply. Each power rating is available as B3 (feet), B35 (feet and flange) or B5 (flange), the flanged versions mounting directly on pump carriers and gearboxes. Ambient temperature -15 to +40 °C. The largest frame size 132 has a cast iron housing.
