Integrated inverter asynchronous electric motor
0.37 - 15.0 kW, 230 - 400 V | SMI series MGM Motori Elettrici

SMI series is made up of single and three-phase asynchronous electric motors with integrated frequency converter. Power range is between 0,37 kW and 7.5 kW (frame size from 71 up to 132). Unit is made up of a high-efficiency three-phase asynchronous electric motor and a compact frequency inverter placed at the non drive end. The SMI series motors are TEFC, IP 55 (available IP56), class F (class H available). SMI motors offer a wide range of overload capacity and a high thermal reserve. The frame consists of aluminium alloy. Shields and flanges are aluminium up to axis height 90 and cast iron from 100 up to 132 frame size . The inverter housing is isolated from the motor in order to avoid heat transmission (patented system); inverter dissipator is self-ventilated. The frequency converter electronics is very reliable as it has been developed in cooperation with the main inverter manufacturer companies; control can be V/F type (frequency voltage control) or SLV type (sensorless vector control). SMI motor can be easily programmed using only three buttons. On request, motor can be arranged for main Bus fields (Profibus, Interbus-S, Device, etc.):
SMI motors are projected as built-in inverter motors and not just as simple assembly of a standard motor with an inverter.
