In this paper, an exact analytical solution based on Fourier analysis is proposed to compute
the cogging torque in a surface-mounted permanent magnet synchronous machine. The …

In this study we developed a brushless DC (BLDC) slotless motor with toroidal winding. The
proposed toroidal winding is a method of winding a coil around a ring-type stator yoke in the …

Rotor eccentricity occurs during manufacturing, causing the device to vibrate and make
noise, thereby shortening its life. Its characteristics can be analyzed via the existing finite …

This study presents the characteristics and performance of a motor at the operating point
based on pulse-width modulation (PWM). PWM is used in modulating the output voltage of a …

Permanent magnet synchronous motors (PMSMs) having high power density and high
efficiency are rigorously researched in various premium applications. Among PMSMs, many …

Low-speed-high-torque permanent magnet synchronous motor (LSHTPMSM) is widely used
in industrial applications. However, the torque density of conventional LSHTPMSMs is not …

In this paper, we present a comparative analysis of surface-mounted permanent magnet
synchronous motors (SPMSM) and interior permanent magnet synchronous motors (IPMSM) …

This paper proposes a high-precision mathematical modeling scheme for interior permanent
magnet synchronous motors (IPMSMs), which gives full consideration to the saturation and …

In this study, we performed an electromagnetic characteristic analysis of a permanent
magnet synchronous machine considering the current waveform based on static rotor …

This paper analyzes the dynamic characteristics of interior permanent magnet synchronous
motor (IPMSM), taking in to account the outer disturbance to a motor system. Based on the …
