With a rated output of 0.75 kilowatts, the motor is among the smallest series types of its class, of the kind fitted to centrifugal pumps, extraction systems or small stirrers. In this output range the frame size is correspondingly compact, typically with a shaft centre height well under 100 millimetres, and the dead weight stays light enough for manual handling.

Under IEC 60072 the frame size sets the shaft centre height and therefore the foot and flange dimensions, so that motors of the same frame size from different makers stay mechanically interchangeable. The squirrel-cage rotor is standard in industrial motors of this kind, while slip-ring rotors are reserved for high starting torque. Protection ratings follow IEC 60529, mounting arrangements IEC 60034-7, for example IM B3, IM B5 or a vertical V1 version. Running it from a frequency inverter raises the demands on winding insulation.

Before buying, check the rating plate and whether voltage and frequency match the intended supply. Turned by hand, the shaft should run freely and quietly; rattling or catching points to worn bearings. The terminal box and cabling deserve a look for corrosion or cracked insulation, which an insulation test clarifies. For inverter duty the winding must be rated accordingly, otherwise premature insulation failure can follow.
