Designing of traction motor stators core

Electric drive is widely used in automotive practice. Its basis an electric traction motor (TM), which, compared with internal combustion engine (ICE), has such advantages as high efficiency, overload capacity, a wide range of speed control, and the possibility torque direct transmission to wheels. The main requirements for are efficiency over entire load range, ease small weight dimensions, regenerative braking capability, control simplicity maintenance. most motors synchronous machines excitation from permanent magnets (PM). They characterized by density, power consistency range. However, there number problems that hinder introduction these home cars, one which lack methodology choosing design armature inductor at stage calculating dimensions TM magnetoelectric excitation, taking into account variety schemes methods winding, PM placement inductor. article deals issues electromagnetic loads various cooling methods, size non-magnetic gap, algorithm calculation based on maximum torque, containing refining cycles, proposed. values inductances factors determined numerical simulation magnetic field. features circuit core winding considered. Distribution curves magnetomotive forces distributed concentrated windings obtained, their harmonic analysis made, recommendations given configuration TD active zone.
