Full Description
Reluctance motors induce non-permanent magnetic poles on the ferromagnetic rotor; the rotor does not have any windings and torque is generated through magnetic reluctance. Synchronous reluctance motors (SyRMs) have an equal number of stator and rotor poles. Reluctance motors can deliver high power density at low cost, so they are finding increasing application in the transport sector. Disadvantages include high torque ripple and the complexity of designing and controlling them. Advances in theory, computer design, and control electronics can overcome these issues.
This hands-on reference covers the concept and design of synchronous reluctance motors. It conveys all key topics required to understand this technology. Chapters cover magnetic materials, geometry, modeling, design and analysis, optimization, production technology, fault-tolerance, experimental validation, and self-sensing-oriented optimization.
Synchronous Reluctance Machines: Analysis, optimization and applications is ideal for researchers working on electrical machines and motors, particularly electric vehicles. The writers - experts from academia and industry - provide the reader with an excellent background and understanding of the core concepts involved in synchronous reluctance motors such that they can engage in their own R&D.
