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...

This paper presents the design of a Permanent Magnet Synchronous Motor (PMSM) for traction applications of electric vehicles (EVs). The design is based on the stator geometry of an existing commercial available induction traction motor. The rotor configurations considered in this study are the surface mounted magnet (SPM) and the inset permanent magnet (IPM) types. Both designs are investigated...

Synchronous homopolar motors (SHMs) have been attracting the attention of researchers for many decades. They are used in a variety equipment such as aircraft and train generators, welding inverters, traction motors. Various mathematical models SHMs proposed to deal with their complicated magnetic circuit. However, techniques optimizing not yet proposed. This paper discusses various aspects opti...

The object of research is a pulsating current traction motor. To improve the accuracy its mathematical model, it necessary to use values parameters that are determined in experimental studies electric In particular, important model motor inductance obtained experimentally. A method proposed for calculating armature winding, main poles, additional poles and compensation winding total circuit. ca...

OBJECT Intraoperative dorsal column mapping, transcranial motor evoked potentials (TcMEPs), and somatosensory evoked potentials (SSEPs) have been used in adults to assist with the resection of intramedullary spinal cord tumors (IMSCTs) and to predict postoperative motor deficits. The authors sought to determine whether changes in MEP and SSEP waveforms would similarly predict postoperative moto...
