Optimal Design of Ultra-High Speed Axial Flux Permanent Magnet Motor with Sinusoidal Back-EMF

Vector Control for an Interior Permanent Magnet Synchronous Machine with Maximum Torque per Ampere Strategy

The main objective of this paper is to show a methodology to implement a Maximum Torque per Ampere Strategy (MTPA) in an Interior Permanent Magnet Synchronous Machine (IPMSM). IPMSM ́s have been broadly used on industry in the last years for having excellent dynamic performance and high power density. In this article, vector control and MTPA theory and criteria are firstly detailed. Then, the ma...

Control of a Permanent Magnet Synchronous Motor with Non-Sinusoidal Flux Density Distribution

This thesis discusses various aspects of controlling a permanent magnet synchronous machine with a non-sinusoidal rotor flux density distribution. The transient model of the machine in the rotor oriented dq-frame is derived, including the non-sinusoidal effects. The design of current and speed controllers is also discussed. The current controller is implemented in a permanent magnet machine, in...

Injected Rotor Shape for Five - Phase Surface - Mounted Permanent Magnet

I . Introduction Multi-phase machines offer several key features, such as high reliability, high torque density, and high efficiency . Therefore, they are obtained wide applications from automotive to aerospace [1][2] . One of them is the five-phase PM machine, where the torque density can be improved by injecting third harmonic current . However, in order to maintain high torque density and re...
