摘要： An electrical induction motor may include nine terminals configured to receive nine current inputs from nine output phases of a nine phase inverter. The motor may include nine windings connected to the nine terminals, and a plurality of contactors, wherein each of the plurality of contactors may be selectively opened or closed in a circuit including the nine windings to selectively connect the windings together in one of a mesh configuration or a star configuration. Each of the windings may be selectively connected between two of the nine current inputs, with a phase angle difference between the two current inputs of 40 degrees. Each of the contactors may be selectively opened or closed to establish a span value for the mesh configuration of two, with two being the number of inverter output phases between a terminal of one of the nine windings and a terminal of another of the nine windings connected to the one of the nine windings. The motor may selectively receive a first one of the harmonics of a drive waveform generated by the nine phase inverter and a second, different one of the harmonics of the drive waveform generated by the nine phase inverter.

摘要： A four pole induction machine with an extended speed range includes a stator with six independent stator coil groups (a pair of said coil groups constitutes a stator phase winding) and two current regulated inverters. Each of the inverters supplies currents to three said stator coil groups belonging to three different phases. The induction machine is operated in two operation modes: as a four pole machine, when both inverters supply currents of identical polarity, and as a two pole machine, when the polarity of currents supplied by one inverter is reversed in respect to the polarity of currents supplied by another inverter. The switching from the four pole operation mode to the two pole operation mode takes place during a constant power operation of the induction machine.
