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 ...

Full Parameter Estimation for Permanent Magnet Synchronous Motors
IEEE transactions on industrial electronics (1982. Print), 2021This article elaborates a novel online full parameter estimation method for permanent magnet synchronous motors (PMSMs). Usually, only two parameters can be estimated using voltage functions in the d-q frame due to the problem of rank deficiency. The α-β

Online Stator Inductance Estimation for Permanent Magnet Motors Using PWM Excitation
IEEE Transactions on Transportation Electrification, 2019The permanent-magnet motors are widely used especially in traction and power steering motor drive applications in automotive. Accurate knowledge of machine parameters, such as the inductance, is essential for efficient and optimal control of the machine.

The permanent magnet synchronous motor
Proceedings of the Institution of Electrical Engineers, 1962A 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, 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.

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.
