A METHOD FOR CONTROLLING A SYNCHRONOUS DOUBLE STATOR ELECTRIC MACHINE

摘要

A method for controlling a synchronous double stator electric machine. A first stator (200) and a first set of magnetic poles (150) on a common rotor (100) forms a first electric machine (510). A second stator (300) and a second set of magnetic poles (160) on the rotor (100) forms a second electric machine(520). The first electric machine and the second electric machine is shifted mechanically by a predetermined angle (γ). An electrical shift is produced to the control of at least the mechanically shifted electric machine with a respective frequency converter in order to at least partly compensate for the mechanical shift in the mechanically shifted electric machine.
