Comparing the Surface- and Interior Permanent Magnet

This paper will compare the surface permanent magnet (SPM) machine to the interior permanent magnet (IPM) machine with fractional slot concentrated winding (FSCW). Key features is to achieve high field weakening with low losses, while keeping a high torque at rated speed. A walk through of essential theory concerning field weakening will be done.

Optimal Design of a Surface Mounted Permanent

2014-8-6  Abstract— This paper presents the optimal design of a surface mounted permanent-magnet (PM) Brushless direct-current (BLDC) motor meant for spacecraft applications. The spacecraft applications requires the choice of a motor with high torque density, minimum cogging torque, better positional stability and high torque to inertia ratio.

A surface permanent-magnet vernier machine (SPMVM) has a toothed-pole structure, and its highly nonlinear relationship between its dimensions and magnetic field makes its design cumbersome. This paper presents a generic design methodology for the machine which brings out its torque-maximizing structure in a convenient manner. Various suggestions concerning the design of the SPMVM are also

Modeling of Surface-Mounted Permanent Magnet

2010-7-29  Abstract: This paper develops and analyzes a parametric model for simulating healthy and faulty surface-mounted permanent magnet synchronous motors. It allows studying the effects of stator winding interturn short-circuit faults. A relevant feature of the developed model is that it deals with spatial harmonics due to a nonsinusoidal rotor permanent magnet configuration.

Permanent Magnet Synchronous Motors: Types &

2021-6-22  Depending on how magnets are attached to the rotor and the design of the rotor, permanent magnet synchronous motor can be classified into two types: Surface permanent magnet synchronous motor (SPMSM) Interior permanent magnet synchronous motor (IPMSM). SPMSM mounts all magnet pieces on the surface, and IPMSM places magnets inside the rotor.
