    Abstract: The invention concerns a method and an apparatus for controlling a three-or-more-phase motor (2) driven by a frequency converter (1). In the method, a change-over switch (3) of the frequency converter is controlled to a continuously conducting state (12,24) and at the same time the phase voltages or phase currents of the other phases are controlled by switching the change-over switches (3) in those motor phases at a switching frequency substantially higher than the frequency of the fundamental wave of the phase voltage or phase current. The apparatus comprises in conjunction with the frequency converter (1) a number of change-over switches (3), at least one change-over switch for each motor phase (17). The change-over switches comprise controllable change-over contacts (4,13). The apparatus further comprises in conjunction with the frequency converter means (5) for determining the motor phase currents and means (6) for controlling the change-over contacts.
