The permanent magnet synchronous motor

Proceedings of the Institution of Electrical Engineers, 1962
A synchronous motor, constructed by modifying an induction motor by fitting a permanent magnet inside the squirrel-cage rotor, is very useful for drives where synchronous operation is required or where the drop in speed of an induction motor is too great.

PERMANENT-MAGNET ROTARY MOTORS

HUMAN. ENVIRONMENT. TECHNOLOGIES. Proceedings of the Students International Scientific and Practical Conference, 2018
Different types of traction motors (DC, asynchronous, valve with excitation from permanent magnets) are compared. It is demonstrated that a valve motor with excitation from permanent magnets is the most suitable for using in electric vehicles and electric buses.

Analysis of permanent magnet synchronous motors

IEEE Transactions on Industry Applications, 1991
A detailed representation of buried permanent magnet synchronous motors at steady state is presented. An equivalent circuit is proposed that accounts for the saliency of the machine and for the particular influence of iron core losses on the machine operations.

Permanent Magnet Synchronous Motor

2020
The mathematical three-phase model of these motors is obtained. Then the standard dq or Park’s transformation is derived and applied to obtain the standard motor dq dynamical model. These results are employed to solve the velocity and position regulation problem. A pendulum is included as a load in the position control problem.

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
