Modeling Of Permanent Magnet Motor Drives

SPIE Proceedings, 1987
Recent research has indicated that the permanent magnet motor drives which include the permanent magnet synchronous motor (PMSM) and the brushless DC motor (BDCM) could become serious competitors to the induction motor for servo applications. The PMSM has a sinusoidal back emf and requires sinusoidal stator currents to produce constant torque while the

Permanent-magnet motors for brushless operation

IEEE Transactions on Industry Applications, 1990
The design considerations for permanent-magnet motors intended for brushless operation are discussed. Two rotor configurations are described: the imbricated rotor and the segmented rotor. The segmented rotor is designed specially for high-speed operation.

Simple Nonlinear Magnetic Analysis for Permanent-Magnet Motors

IEEE Transactions on Industry Applications, 2004
This paper presents a simple nonlinear magnetic analysis for a surface-mounted permanent-magnet synchronous motor as an assistant design tool of finite-element analysis (FEA). The equivalent magnetic circuit of the motor used in the proposed analysis is composed of the saturable permeance tips in the stator teeth for considering the local magnetic ...

Magnetic Shielding for Coreless Linear Permanent Magnet Motors

Applied Mechanics and Materials, 2013
This paper concerns the local reduction of the magnetic flux density by means of magnetic shielding. Using a spatial frequency description, a 2-D semi-analytical periodic model is obtained for a coreless single-sided linear permanent magnet motor. The magnetic shield is included in the modeling using mode-matching. The obtained magnetic flux density is

Permanent magnet synchronous motor emulator

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
In order to test the performance of the motor driver, a power converter can be used to replace the real motor, both of which have the same electrical characteristics. This is a real-time control system. The foremost challenge in this system is the modeling of the real-time motor simulator based on the mathematical model of permanent magnet synchronous ...

Permanent-magnet motors

1996
Abstract New electromechanical drive systems endowed with a combination of desirable characteristics are a considerable impetus to technological progress. Taking a robot axis drive as an example, it should combine a low moment of inertia and low torque pulsations with high power/weight ratio, high torque overload capability and high ...
