An open-end winding permanent magnet synchronous motor (PMSM) has a larger range of speed regulation than normal PMSM with the same DC voltage, and the control method is more flexible. It can also manage energy distribution between two power sources without a DC/DC converter. This paper aims at an electric vehicle equipped with OW-PMSM drive system with dual power sources and dual inverters; ba...

This article describes a practical method for predicting the distribution of electric potential inside an electrical machine’s winding based on design data. It broadens understanding impedance in terms inter-winding behavior and allows to properly insulation system during development phase. The predictions are made frequency-dependent equivalent circuit machine which is validated by measurement...

K. D. Hoang, Y. Ren, Z.Q.Zhu*, M. Foster Abstract—The switching-table-based direct torque control strategies (ST-DTC) of dual-three phase permanent magnet synchronous machine (PMSM) drives are investigated in this paper. Owing to its inherited advantage of suppression of sixth harmonic torque pulsation, dual-three phase machine has attracted more and more interests among various sorts of multi-...

The paper presents an electromechanical auto synchronized wind energy conversion system (WECS) for larger penetration of renewable energy sources (RES) in the rural electrification systems. The architecture of the WECS uses two stator windings at power frequency which provides harvesting of power to flow from WECS to load and to grid side when the generated power is in access. Asymmetrical six ...

Stator grounding is the most common fault of a large generator. If accurate coil can be located quickly and effectively, maintenance progress generator greatly sped up, put back into use as soon possible. For this purpose, stator location method for steam proposed, which takes distribution winding potential account. Firstly, characteristics influence are analyzed when single-phase ground occurs...

In this paper, a dual-rotor slotless axial-flux permanent magnet (AFPM) motor with equidirectional toroidal winding (ED-TW) is proposed and compared the AFPM traditional (T-TW) same dimensions, number of coils poles. Different from T-TW, only positive sides ED-TW are left on one side stator core, return all removed to other core. Firstly, structure operation principle two motors introduced anal...
