Some key problems in designing low-speed gearless permanent magnet synchronous motor (PMSM) is discussed in this paper. Firstly, measures to reduce harmonic torque are proposed. Secondly, magnetic circuit structure of PMSM is surveyed to make corresponding selection. At last, finite element analysis of a low-speed gearless PMSM for elevator drive is proposed. A real PMSM product verified the design.
