Motor training results in encoding of motor memories, a form of use-dependent plasticity. Here we tested the hypothesis that transcranial magnetic stimulation (TMS) synchronously applied to a motor cortex engaged in a motor training task could enhance this plastic process. Healthy volunteers were studied in four sessions: training consisting of performance of directionally specific voluntary th...

In this paper we want to describe proposal of the fuzzy control of synchronous motor with permanent magnet and impact of deployment of membership functions of fuzzy controller on a regulation quality of a synchronous permanent magnet motor (PMSM). In the first part of this paper is described mathematical model of synchronous motor with permanent magnets and designed controller by using fuzzy lo...

Axial flux electric motors have received a lot of attention in recent years due to successful implementations industrial or traction applications. Particularly, axial permanent magnet synchronous (AFPMSM) can be an attractive choice case high torque-density requirements when the drive environment (packaging) is geometrically limited disc-shaped motor. However, compared radial motors, machine mo...

Objective: This research aimed to compare the motor skills among students with intellectual disability, stuttering, articulation problems and normal speech. Methods: The study was a retrospective causal-comparative research. From among all elementary male students with intellectual disability in Urmia city, 90 students (30 students in each group) were selected. All groups completed the revised ...

For the permanent magnet linear synchronous motor (PMLSM) applied in the high-precision equipment, motor control system should have characteristics of high dynamic response and strong robustness. Predictive current control is an effective method to improve the dynamic response of the system, but it requires accurate motor parameters. This paper presents an improved deadbeat predictive current c...

The induction or synchronous motor can temporarily produce voltage such as a generator after disconnection from the power system. Subsequently, voltage and frequency differences between the motor terminal and the power system are gradually increased. In such conditions, the mechanical damages to motor may be occurred during motor reconnection when the synchronizing conditions are not complied. ...

in this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (lims). dynamical equations of lim have been considered accurate. in other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. then equations of the reference model and adaptive mode...
