Abstract (en)
[origin: WO2015092759A2] An electric motor, comprises a stator (2) provided with stator windings (4), a rotor (3) provided with rotor windings (5) and electronic means for electronic switching. Advantageously said rotor windings define inductive elements for causing a rotor voltage drop (AVR) in the current circulating therein with respect to the supply voltage (VM) supplied thereto, said electronic means for electronic switching operating electrically in series with said rotor windings to work at a voltage (Vs) corresponding to the voltage (VM) with which said rotor windings (5) are supplied decreased by said rotor voltage drop (AVR), thereby allowing the use of low voltage electronic switching means.
