This paper proposes a dual-harmonic pole-changing (PC) motor with split permanent magnet (PM) poles (DHPCM-SPMPs). By adopting PM pole structure, the amplitude of third flux density is increased greatly. Therefore, when PC winding adopted to couple fundamental and components, respectively, proposed can work as satisfy operating demands electric tractors. The design effect structure introduced f...

Abstract To repress the torque ripple of switched reluctance motor, this study takes a three-phase 12/8-pole motor as an instance and simulates electromagnetic field using Maxwell finite element software to analyze influence characteristics pole arc parameters on motor. In conjunction with Workbench platform, response surface method multi-objective genetic algorithm are used optimize coefficien...

It has been previously demonstrated that an induction machine drive with contactorless pole changing can be achieved by reversing current directions of certain stator coil groups. This paper compares the power and torque capability of this drive with conventional four-pole and two-pole induction machine drives. Based on the technique of vector space decomposition, the machine coupled-circuit mo...

Autism is a neurological disorder that occurs during childhood and is characterized by impairments in social interaction and communication, as well as restricted and repetitive behaviors. Abnormalities of the cerebellum in autism include Purkinje cell loss and motor disturbance. In the present study, we evaluated the effect of treadmill exercise on motor coordination and balance in correlation ...

The switched reluctance motor (SRM) is recently gaining huge popularity in electric vehicle (EV) applications due to its control flexibility, simple structure, lower cost and high efficiency than the synchronous induction motors. Among all controllers, direct torque (DTC) most preferred higher efficiency, losses superior characteristics. In this paper, a 6/4 pole SRM with fuzzy logic based DTC ...

In this study, the performance analysis of a 5.5 kW, 460 V, 60 Hz, 4-pole, and 3-phase squirrel- cage induction motor (IM) has been carried out by developing portable electronic circuit, design, software, independent any commercial software. The mathematical equations used in design steps preliminary main dimensions squirrel IM are realized with developed circuit. To perform calculations Nextio...

Phytochrome is thought to control the induction of leaf senescence directly, however, the signalling and molecular mechanisms remain unclear. In the present study, an ecophysiological approach was used to establish a functional connection between phytochrome signalling and the physiological processes underlying the induction of leaf senescence in response to shade. With shade it is important to...
