Abstract :
This paper introduces a two-pole three-phase high-power line-start permanent magnet synchronous motor (PMSM). First, the operating principle and structural features of the line-start PMSM are described. An interior PM rotor structure is presented, which adopts a radial-set of permanent magnets with multi-section for each pole. A motor model is then established by employing the finite element analysis software JMAG-Studio. The transient electromagnetic field is calculated and analyzed using the time-stepping FEM coupling with magnetic field analysis with electrical circuits. The starting process and steady-state performance are simulated, and the rationality of the motor design is validated.
