<p>The present invention relates to a squirrel-cage induction motor for frequency converter use. in particular, which squirrel-cage induction motor comprises a stator, a stator winding arranged in its axial grooves, divided into at least two coil groups (3A, 3B) for each phase of the supplying alternating current and connected to the supplying alternating current in such a manner that the sum of basic frequency groove currents is substantially zero at each moment. In accordance with the invention, one half (3A) of the coil groups of each phase is connected to the supplying alternating current at one end (N) of the stator and the other half (3B) of the coil groups of each phase at the other end (D) of the stator. <IMAGE></p> |
