High speed Permanent Magnet Synchronous Motors (PMSM) are used in electrical vehicles because of their strong power density. The high speed implies a big electromotive force and requires flux-weakening. Usual control algorithms do flux-weakening by adding negative Id current when the required voltage by the current regulation exceeds the maximum voltage depending on the battery. If the magnet can...
This contribution introduces proposed control of a wheel drive with permanent magnet synchronous machine (PMSM) intended for a new generation of 100-percent low-floor trams. The proposed control is based on a field oriented control linked to a rotor flux. The control strategy consists of two control algorithms which are changed based on the rotor speed. The proposed control fully satisfies demanded...
In this paper, the design and performance analysis of a robust and inexpensive permanent magnet-assisted synchronous reluctance generator (PMa-SynRG) with its corresponding control topology is studied. More specifically, the topology based on vector control for the maximum output power of generator is investigated. The torque of PMa-SynRG is controlled by a combustion engine speed and the maximum...
