Dynamic and steady-state performance of line-starting permanent magnet motors
2010
This paper presents two types of prototype motors for line-starting permanent magnet motors; one is a non-salient- pole machine, and the other is a salient-pole machine. Through both the analyses and the experiments, it is proved that the reluctance torque utility boosts up not only the steady-state characteristics but also the line-starting capability. It is also noteworthy that in the steady-state operation the salient-pole machine can realize not only the better efficiency but also the higher power factor. Results are given for a two-pole prototype motor with P N = 5 kW, n N = 3000 min −1 , V N = 200 V, Y-connection.
