Known flat winding layers that can be prefabricated and inserted into soft magnetic bodies insufficiently utilize the available space in the grooves and winding overhang of polyphase machines and thus increase the volume and weight of the machine. A new winding design allows high power and force densities to be obtained, thanks to the utilization of the whole available space, and are economic to produce. For that purpose each winding layer (4d) is composed of several conductor lanes (22-24) whose number corresponds to the number of phases. The height of the conductor lanes is reduced at the points (25-33) where they intersect,due to the fact that the conductors are mutually offset, and thus pass over each other inside the layer. By variably adapting the width of the conductor the space in the winding overhang through which the magnetic flow is directed in the soft magnetic body is utilized. The space available in the winding overhangs is completely utilized thanks to double winding layers of which each second layer mirrors the first and is offset by a pole pitch with respect to the first. The winding is suitable fox motors and generators whose volume and weight can be advantageously reduced. |
