Volume 1, Issue 3 , Autumn 2019, , Pages 42-50


  In the PMSM, by creating a sinusoidal distribution for conductors at the stator surface, the airgap’s flux density is closer to the sinus form [1]. By replacing the field’s winding with a permanent magnet, the brushes, slip-rings, and copper losses could be removed from synchronous motor. ...  Read More

2. A Comprehensive Review on High Speed Permanent Magnet Motors and their Modern Applications

Arsalan Hekmati; iman sadeghi

Volume 1, Issue 2 , Summer 2019, , Pages 59-65


  Synchronous speeds in all types of alternating current machines depend on the frequency of the power grid, and performance at higher speeds at steady conditions requires higher frequency feeds. The development of speed control drive technology in recent decades has prompted renewed attention to high-speed ...  Read More

Volume 1, Issue 4 , Winter 2019, , Pages 21-30


  This paper contains an investigation about using electric buses alternatively in a BRT line in Tehran. In order to reach this purpose driving cycle of electric bus for different bus routes are simulated and studied. Also with the aim to choose the pilot route, several criteria such as, air and noise ...  Read More
