Futo Other models

With a rated output of 1.1 kilowatts, the motor is among the smaller versions of the Y-series, sufficient for small pumps, fans or stirrers. Motors in this series are designed for straightforward maintenance and wide availability of spare parts, making them a common choice for standard applications.

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.
