- Protection
- IP55 – IP65
The working portfolio behind most plant installations: pumps, fans, compressors and conveyors running continuous duty in a non-hazardous area.
Machines are supplied to IEC dimensions with IE2, IE3 and IE4 efficiency classes. Where a plant standard requires a non-IEC shaft height or a specific terminal-box position, the same series is available as a modified build.
Both squirrel-cage and slip-ring rotors are offered. Slip-ring machines remain the practical answer for high-inertia starting against a stiff supply.
Key characteristics
IE3 and IE4 across the range
Efficiency class is stated per variant, not per series, so an EU ecodesign check can be made from the catalogue.
Standard IEC interfaces
Shaft height, flange and shaft dimensions to IEC 60072 for direct replacement of an existing machine.
VFD-ready insulation
Reinforced insulation system and optional insulated bearings for inverter supply.
Vertical construction available
IM V1 and IM V10 arrangements with thrust bearings for deep-well and vertical pump sets.
Construction
- Cast-iron or steel frame depending on frame size
- Class F insulation, Class B temperature rise
- Regreasable bearings from frame 160 upward
- Terminal box rotatable in 4 × 90° positions
- Condensate drain plugs in both end shields
Available configurations
- Horizontal foot, flange and foot-flange mounting
- Vertical shaft-down and shaft-up with thrust bearing
- Squirrel-cage or slip-ring rotor
- Second shaft extension, encoder, brake
- Marine and tropical climatic versions
Monitoring options
- PTC thermistors in the winding as standard from frame 200
- Pt100 winding and bearing sensors as an option
- SPM / vibration measurement nipples
3 series, 13 models
A series shares one design; the variants below differ by frame size and rating. This table is generated from the series definition — the variant list is never maintained by hand.
AM — general-purpose series
Standard IEC three-phase asynchronous motors, cast-iron frame, IE3 as standard and IE4 on request.
