| Abstract |
This paper illustrates a procedure to individuate the parameters and the volt-ampere ratings of an interior
permanent magnet synchronous motor drive to meet a prefixed torque-speed operating characteristic, taking
into account the iron saturation (saturated motor). This is achieved by an appropriate model of the magnetic
flux-current curves of the motor. A well-suited normalisation with base speed and related torque as base
quantities is proposed to generalise the results as much as possible. Particular attention is devoted to the
comparison between motor parameters and capabilities of unsaturated and saturated motor drives in the whole
speed range including the flux-weakening region. Then the paper indicates some guidelines for the design of
the motor in order to satisfy the required torque-speed specifications. It is shown that an accurately designed
saturated motor may exhibit the required performance with smaller dimensions than an unsaturated one. |
