This chapter discusses surface‐permanent‐magnet (SPM) ac motors. While the SPM ac machine is widely used in industrial applications, its sibling, the interior‐permanent‐magnet (IPM) machine, is the machine of choice for electric powertrains. The chapter provides the necessary background for the investigation of the IPM machine.
2011-11-9 Abstract: This paper proposes an improved method for the estimation of position, velocity, and disturbance torque in a surface permanent-magnet (SPM) machine self-sensing (position sensorless) drive that uses high-frequency (HF) voltage injection.
2019-3-25 design the high-efficiency surface permanent magnet synchronous motor (SPMSM) or generator (SPMSG). The air-gap and permanent magnet size can be approximately determined based on our mathematics model, which is the most important part of SPMSM design. From our method, we can know that motor’s power out torque is related to the torque

2017-1-20 The magnetic fields from a permanent magnet can readily be understood by looking to the magnetic surface currents that result from the magnetization of the magnetic material.
A Generalized Magnetic Circuit Modeling Approach for Design of Surface Permanent-Magnet Machines Abstract: This paper proposes a generalized equivalent magnetic circuit model for the design of permanent-magnet (PM) electric machines.
