The Study of Permanent Magnet Demagnetization in Permanent Magnet Synchronous Motor
2021 IEEE International Conference on Advances in Electrical Engineering and Computer Applications (AEECA), 2021Permanent magnet demagnetization is one of the common faults of permanent magnet synchronous motor, which seriously threatens the safe and reliable operation of the motor and reduces the service life of the motor. Based on the principle of permanent magnet demagnetization, this paper analyzes the causes of irreversible permanent magnet demagnetization.

Permanent-magnet motors for brushless operation
IEEE Transactions on Industry Applications, 1990The 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.

Permanent magnet synchronous motor emulator
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017In 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 ...

Analysis of permanent magnet synchronous motors
IEEE Transactions on Industry Applications, 1991A 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.

Modeling Of Permanent Magnet Motor Drives
SPIE Proceedings, 1987Recent 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

Torque maximization for permanent magnet synchronous motors
1997 European Control Conference (ECC), 1997The paper discusses the problem of maximizing the torque of permanent magnet synchronous motors in the presence of voltage and current constraints. Formulas are given that are suitable to operation with voltage and current source inverters and to real-time computation.

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 ...

PERMANENT-MAGNET ROTARY MOTORS
HUMAN. ENVIRONMENT. TECHNOLOGIES. Proceedings of the Students International Scientific and Practical Conference, 2018Different 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.

Permanent Magnet Synchronous Motor
2020The 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.
