Study on Low-Speed High-Torque PMSM for Surface-Drive System of Progressive Cavity Pump

Article Preview

Abstract:

This paper focus on a surface-mounted low-speed high-torque permanent magnet synchronous motor (PMSM) for progressive cavity pump wells. To minimize torque ripple, several methods is used such as proper pole-arc coefficient and fractional-slot windings. In the motor design, a non-linear finite element analysis (FEA) method is conducted to compute the performance of the motor. Through the simulation and experiment, the result shows that the design of low-speed high-torque PMSM is valid and presents a good performance.
