In this article, a suspension-guided permanent magnet synchronous linear motor (SG-PMSLM) for ropeless elevator is proposed, which can meet the requirements of high thrust and density elevator, reduce vibration noise wheel-rail wear during operation. The structure, working principle electromagnetic characteristics SG-PMSLM are analysed. order to improve overall performance SG-PMSLM, article aim...

The paper is concerned with designing an effective controller for a linear tubular homopolar (LT-H) motor type. construction and operation of the LT-H are first described in detail. Then, model represented direct-quadrature (d-q) axes order to facilitate design control loops. designed system consists two main loops: current loop velocity adaptation loop. determination regulator’s gains accompli...

The relevance of the study is due to widespread use turbomechanisms (pumps, fans, compressors) in various industries. For electric drives these mechanisms, urgent task increase speed rotation motors. This associated with an productivity turbomechanisms, which affects volume production products. However, commercially available AC motors at network frequency 50 Hz have rotational speeds no more t...

Nearly all of the electrical power used throughout the world is generated by synchronous machines driven by either hydro or steam turbines or by combustion engines. Synchronous Machine is generally dedicated to high power due to the fact that they have a controllable power factor and a higher efficiency than the induction motor of corresponding rating. In recent years different control schemes ...
