Hybrid Reluctance Machines with U-Shaped Electromagnets and Permanent Magnets

Linear Transverse Flux Reluctance Machine with Permanent Magnets

A new structure of linear transverse flux machine (TFM) is presented in this paper. It is in fact a variable reluctance linear machine having permanent magnets on the mover. Its structure and its working principle will be discussed. After a preliminary design of the motor a 3D FEM analysis was carried out before optimizing the designed linear motor. The flux densities in the machine and the sta...

Synchronous Motor with Hybrid Permanent Magnets on the Rotor

Powder metallurgy allows designers of electric motors to implement new magnetic circuit structures. A relatively new concept is the use of a magnet system consisting of various types of magnets on one rotor, for example sintered and bonded magnets. This concept has been applied to the design and manufacture of the four-pole rotor of a synchronous motor with 400 W power and a rotational speed of...

Comparative Study on Different Variable Reluctance Linear Machine Structures (With/Without Permanent Magnets)

Design of a Synchronous Reluctance Motor Assisted with Permanent Magnets for Pump Applications

This Master thesis focuses on the design of a high efficiency Permanent-Magnet-Assisted Synchronous Reluctance Motor (PMASynRM) intended for pump applications. The new motor is designed to replace an existing Induction Motor (IM) in a pump product. The basic principles of SynRM, and PMASynRM Motors and a good analytical model were introduced. Due to the complexity and high non-linearity of this...

Voltage control of switched reluctance machines for Hybrid Electric Vehicles

The rugged low-cost construction and constant power profile of a switched reluctance motor (SRM) make it suitable for hybrid electric vehicles (HEVs). This paper describes the development of a voltage-based control strategy for a SRM. The controller design is influenced by project constraints and goals as well as the use of a new power topology. A prototype SRM and controller were built and ful...
