The MII model, an acronym of Motor with Integrated Inverter, developed by Carpanelli Motori Elettrici S.p.a., consists in the symbiosis between an asynchronous three-phase special motor for inverter, in standard manufacturing versions (IEC 34.7 and IEC 72.1) and special ones, and a frequency converter with the use of Igbt and last generation microprocessors.

MII is characterised by its compact shape, with a diameter of a self-breaking motor, and for the frequancy converter in the rear of the motor. Its shape favours the expolitation of the airflow of a permanently operating fan for interesting performance concerning mechanical couples.
