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.

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 ...

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.

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.

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

Torque maximization for permanent magnet synchronous motors

1997 European Control Conference (ECC), 1997
The 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.

Permanent Magnet Motor Safety

SPE Gulf Coast Section Electric Submersible Pumps Symposium, 2021
Abstract As Permanent Magnet Motors (PMMs) become more widely used because of their many benefits, awareness of the potential safety hazards arising from their differences from Induction Motors (IMs) is important. Due to their construction, the magnetic field presence is always "on" with PMM – even when not under energized electrical ...

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.
