Original Abstract
The contribution describes a development of a permanent magnet synchronous machine with a non-usual geometry of the magnetic circuit. The construction description, some theoretical calculations and practical measurement results are included. Using the axial flux geometry it is enabled to choose the winding cross-section independent on the cross-sections of the magnetic circuit elements. The advantage of this solution consists in the possibility to achieve low resistance losses without an unacceptable rise of the stator iron volume. Further a segmental stator winding topology was used in this construction. No crossings of the coil overhands of all phase-windings each other appear. The main gain of this fact consists in a reduction of the length of the winding wire so in a farther decreasing of the winding resistance losses. The low resistance losses destine the constructed machine for using in small traction drives (low voltage battery or fuel cell electric vehicles). The machines in these applications operate often with a torque (current) overload and so the resistance losses are dominant ones. Their reduction brings an increasing of the vehicle action radius.
