Abstract (en)
[origin: WO02089306A1] An electrical rotating apparatus is provided that has variable impedance. This is achieved by connecting one of the polyphase components(406) of the apparatus in a mesh connection. The spanning value, L, of such a mesh connection may be varied by changing the harmonic content supplied by an inverter component. Also provided is a method for connecting an inverter to a motor, wherein a switching arrangement(414) permits the simple alteration between various mesh connections of different span value, changing thereby the Volts/Hertz ratio of the motor.
