| Abstract |
An internal permanent magnet (IPM) motor
may be used as a suitable electric vehicle drive. This paper
presents the results of optimal design of such machine as
starter/generator of a hybrid electric vehicle (HEV). The
required performance in HEV is a constant power over a
wide speed range. In IPM machine, direct control of the
PM flux is not possible but d-axis armature current can
weaken the air gap flux. However, in this method,
demagnetization effect caused by the reaction of the abovementioned
current must be prevented. The vector control
method is used in order to extend the performance range of
the IPM motor. Efficiency and performance characteristics
are considered as objective functions and an optimal design
technique is applied to maximize the efficiency and achieve
a good performance. Genetic algorithm is employed as
optimization routine in order to find the optimum design
variables of the objective function. |
