Abstract

Known multi-phase electric machines have conductor lanes which do not sufficiently utilize the space available in the grooves and winding overhang or which are costly to produce. Besides a good utilization of the available space, the length of the conductors in the winding overhangs should be kept short in order to obtain high effiency and power densities, and the number of different conductor designs should be minimized in order to reduce production costs. According to the invention, the electric machine consists of several electric pole units which have each a small number of phases and poles with alternating polarity in the direction of displacement. The electric pole units are located next to each other in the air gap and are mutually offset by a fraction of a pole pitch with respect to the rotor poles. Their meandering rectangular conductor wires extend in layers parallel to the air gap. In monophase electric pole units, the conductor insulation is designed for only a fraction of the terminal voltage; by small increments a high effective conductor proportion is achieved. The modular design allows electric machines to be assembled from a few different structural shapes which, because of their simple design, may be produced on a large scale in a totally automated manner.
