The main goal of optimal design of single phase induction motors with permanent capacitor is maximization of the efficiency and minimizing the manufacturing cost. Mathematical classic methods can be used for design of these motors but they need to linearization and simplification in model and formulas. This linearization is caused that design precision decreases while random search methods such...
In the presented paper, a sensorless driver circuit is designed, constructed and tested to control two types of three-phase Switched Reluctance Motor (SRM). The presented control algorithm has three steps. In the first step, the SRM is controlled by an open-loop method. In the second step, mathematical model of the SRM phase, motor parameters and flux-current-rotor position relation are used in...
Optimal design of single phase permanent magnet brushless DC motor using particle swarm optimisation
Background: Parkinson Disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functions, especially while performing dual tasks--a critical factor in everyday living. However, many controversies exist about the benefits of dual-task training in patients with PD. Objectives: This study assessed the efficacy of motor and cognitive dual-task training in improving balanc...
Sleep has been shown to affect the consolidation of motor memory in adults. However, sleep-dependent consolidation is not well-specified in children as like as adults. So, the purpose of this study is to investigate the effect of sleep on childrenchr('39')s motor memory consolidation. The participants were 32 voluntary boys aging from 10 to 12 years old from city of Kerman, which had the necess...
