Three-Phase Asynchronous Motors .
MS/MH/MP Three-Phase Asynchronous Motor (IE1/IE2/IE3)
General-purpose Boneng three-phase asynchronous motors in three IEC 60034-30-1 efficiency classes: MS — IE1 (0.09–7.5 kW), MH — IE2 and MP — IE3 (0.12–90 kW). Frame sizes 56–280: die-cast aluminium up to 100, grey cast iron from 112. 4 and 6 poles, 50 Hz 220/380–400/690 V and 60 Hz 380–480 V supplies, S1 duty as well as S2–S10 and inverter operation. Totally enclosed fan-cooled IC411 (forced ventilation on request), IP55, class F insulation with class B temperature rise. Options: brake, encoder, PTC, thermal switch or PT100 in the winding, anti-condensation heater. The same motors are fitted to Boneng gearmotors. The manufacturer's website now lists the range as MP (IE3) and MU (IE4) over the same 0.09–90 kW.
