Series-winding three-phase PMSMs have a higher bus voltage utilization than the conventional with star connection. This topology is suitable for applications limited voltage. However, zero-sequence current controller will reduce of series-winding PMSMs, which causes problems in flux-weakening design. The control algorithms cause to enter overmodulation region early and degrade performance suppr...

The direct drive hub motor is a that directly combines the and wheel. It accompanied by development of permanent magnet modern control technology. Permanent synchronous (PMSM) especially suitable for use as its advantages high efficiency, energy saving, power easy control. In this paper, Motor Cad software was applied to optimize design an outer rotor PMSM cellular power, simulation analysis ai...

A voltage-parameter map (VP-Map) is proposed for predicting the performance of electric vehicles (EVs) and hybrid EVs (HEVs), which varies with respect to parameters in a variable load flux-weakening range, determining design parameters. Through this, maximum torque that can be generated at speed, input current generation rated torque, whether vehicle operable light are predicted, suitable 120-...

An experimental investigation is conducted to determine the behaviour of brushless PM synchronous machine parameters in the high speed flux weakening operating range. Real-time operating characteristics are determined for two commercially available 4 N·m interior PM synchronous machines. Special computer assisted measuring techniques are employed using an experimental vector controlled drive, c...

In this paper, a novel intensifying-flux variable flux-leakage interior permanent magnet (IFVF-IPM) machine is proposed, in which flux barriers were designed deliberately between the adjacent poles to obtain effect and property. The rotor topology design principles of proposed are also introduced. Then, multi-objective optimization method adopted based on sensitivity analysis, some variables IF...
