... Abstract: A fault-tolerant permanent-magnet traction module is proposed for subway application, which has three different operation modes: normal, isolation, and fault-tolerant mode. In normal mode, 2 three-phase permanent-magnet synchronous machines (PMSMs) are controlled by 2 three-leg voltage-sou ...

... For the 12-slot motor, the slots/pole is 3, and the coils are full-pitched, which maximizes the width of the back-emf. In the 6-slot motor, the slots/pole is 1.5, and the coil span used is 1 because of which the width of the back-emf waveform is smaller. This effect can also be achieved by short-pit ...

With high-speed current switching in chips and short microstrip in integrated structure, internal electromagnetic fields become very intensive and can produce severe cross talks and magnetic couplings. It is necessary to have some techniques to evaluate these near-field emissions ...

Electric machine

The academic study of electric machines is the universal study of electric motors and electric generators. By the classic definition, electric machine is synonymous with electric motor or electric generator, all of which are electromechanical energy converters: converting electricity to mechanical power (i.e., electric motor) or mechanical power to electricity (i.e., electric generator). The movement involved in the mechanical power can be rotating or linear.Although transformers do not contain any moving parts they are also included in the family of electric machines because they utilise electromagnetic phenomena.Electric machines (i.e., electric motors) consume approximately 60% of all electricity produced. Electric machines (i.e., electric generators) produce virtually all electricity consumed. Electric machines have become so ubiquitous that they are virtually overlooked as an integral component of the entire electricity infrastructure. Developing ever more efficient electric machine technology and influencing their use are crucial to any global conservation, green energy, or alternative energy strategy.
