This paper describes methodology to calculate required motor power rating for elevator and lift application. Switched reluctance motor an excellent candidate for traction applications contributes more in low speed-high torque application. Quality of lift is analyzed by its smoothness, without any jurg. Torque production in motor during acceleration and deceleration decides Smoothness of lift. I...

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...

A series of synchronous reluctance motors (RSM) are analysed using finite element methods. The amount of iron in each rotor is kept the same. It is shown that the saliency ratio is not only dependent on the flux guide reluctance factor but also on the position or span of flux guides. It is also shown that an axially laminated design may not be an optimum configuration due to large number of flu...

A Model-based predictive current control (MBPCC) has recently become a powerful advanced technology in industrial drives. However, MBPCC relies on the knowledge of system model and parameters, being, therefore, very sensitive to parameters errors. In case synchronous reluctance motor (SynRM), where vary due its ferromagnetic structure nonlinear magnetic properties, performance would suffer sign...

This paper is focused on the design, optimisation and control of a permanent magnet assisted synchronous reluctance machine (PMaSynRel) for low cost high efficiency household appliances, in particular motor washing machine. The design aims at maximising torque produced power factor, while minimise oscillations losses, thus improving efficiency. A campaign tests has been carried out prototype op...

An adaptive online flux-linkage estimation method for the sensorless control of switched reluctance motor (SRM) drive is presented in this paper. Sensorless operation is achieved through a binary observer based algorithm. In order to avoid using the look up tables of motor characteristics, which makes the system, depends on motor parameters, an adaptive identification algorithm is used to estim...
