Volume 2, Issue 1 , January 2022, , Pages 52-69

  Permanent Magnets (PMs) are employed in many modern devices, thanks to their unique properties. Electrical machines, i.e., motors and generators, are a major application of PMs, which produce the required magnetic field. When there are severe constraints on the weight and dimensions of the device (e.g. ...  Read More

A Survey on Permanent Magnet Synchronous Machines: Recent Applications and Trends

Arsalan Hekmati; Iman Sadeghi Mahalli; Mohammad Siamaki

Volume 1, Issue 3 , July 2021, , 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

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

Arsalan Hekmati; iman sadeghi

Volume 1, Issue 2 , April 2021, , Pages 61-67

  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
