... 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 ...

Speed Control of High-Speed BLDC with Pulse Amplitude
... 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 ...
