Abstract :
An evolving family of electric machines using the torque magnification (TM) principle has attracted increasing interest in recent years. In this paper the TM principle is described following the introduction of the specific torque density concept. A TM machine with flux concentration effect is presented, and its working principle explained. The design considerations of the machine, which are common to any TM machine, are studied in detail. Test results taken on a hardware prototype machine prove the concept and make clear that the machine´s cost-effectiveness
