摘要：

A constant parameter equivalent circuit model that neglects motor losses is used to determine the effects of dq reactances and open circuit voltage on the power capability of salient pole permanent magnet motors in variable speed drive applications. It is shown that peak power capability over a range of speeds can be obtained by proper control of the armature current magnitude and phase. Due to the voltage constraint imposed at the motor terminals the power capability will fall to zero for most motor designs at a given high speed. A simple relationship between the motor open circuit voltage and the direct axis reactance is derived to obtain motor designs that, even with this voltage constraint in place, extend their theoretical power capability, neglecting losses, to infinite speed. All results are presented in normalized curves using a per unit system. © 1990 IEEE
