The brushless doubly fed reluctance machine (BDFRM) is receiving an increased amount of attention from the research community thanks to its potential as alternative drive for variable speed applications, both motor and generator. Currently, sizing BDFRM in literature based on model ideal axially laminated rotor (ALR) discrepancies are hidden compensation factors which turn tuned with a finite e...

In this thesis, a permanent-magnet assisted synchronous reluctance machine (PMSynRel) design is presented for a plug-in hybrid electric vehicle application. Apart from operating as a traction machine to propel the vehicle, the machine is also used when the vehicle’s battery is charged from the grid. This additional functionality puts restraints (that are discussed in the thesis) on the final ma...

Position sensorless control has been widely studied for electrical rotor position estimation. However, because of the magnetic periodicity, mechanical multipole electric machine was hardly reported. By increasing dimensions, this article proposes novel topologies named as dual-gap dual-pole composite machines, where can be demodulated from positions two air gaps. The and corresponding theory ar...

The switched reluctance machine (SRM) is one of the most interesting machines, being adopted for many applications. However, this requires a power electronic converter that usually fragile element system. Thus, in order to ensure high reliability system, it fundamental design with fault-tolerant capability. In context, new solution proposed give capability This was designed purpose two types sw...
