The analysis of different stator designs of a PMSM for elevator application

摘要

In this paper, permanent magnet synchronous motor (PMSM) used in an elevator which can lift eight people with the linear speed of 1 m/s, is evaluated. Five different PMSMs are designed and compared to each other. Number of poles, load, input voltage and main dimensions (inner and outer diameter of rotor and stator and length) is kept the same for all the motors. However different number of stator slots (36, 48, 54 and 60) and different winding layouts are designed. All the motors are modelled by using ANSYS Maxwell that is finite element method (FEM) based commercial software. The results are compared in terms of the induced voltage, induced voltage harmonics and torque output.
