| Abstract |
Permanent magnet synchronous motors (PMSMs) for the applications such as an electric vehicle,
compressor drives of air conditioner and machine tool spindle drives require a wide constant-power
speed range. In order to improve the efficiency performance in such applications, this paper has
examined the losses and the efficiency characteristics of PMSM mainly in the constant-power speed
region over the base speed. The control strategy in order to offer a high-efficiency operation is
shown and the effect of saliency ratio on the efficiency performance is examined based on the
simulations. The prototype interior PMSM for a wide constant-power operation is designed and
several testes are carried out. The experimental results demonstrate that the prototype IPMSM can
offer a constant-power speed range of 5:1 and it has a high-efficiency performance in the constantpower
speed region. |
