“…The losses (a) and (b) are determined by the current density distribution obtained from (1). The losses of category (c) are calculated for each FE using a standard technique [7,12]. In the considered coupled problems, the windings resistance, the elements of conductances matrix and the reluctance matrix in (1) depend on the temperature.…”

Abstract:The paper presents the special software for transient FE analysis of coupled electromagnetic-thermal problems in a squirrel cage submerged motor working at cryogenic temperature. A time-stepping finite element method and transients analysis of an induction motor has been applied. The non-linearity of the magnetic circuit, the movement of the rotor, skewed slots, and the influence of temperature on electric and thermal properties of the materials has been taken into account. Developed on the basis of presented algorithm a computer program used to analyze the phenomenon of current displacement in the rotor bars of high-voltage cage induction motor working in cryogenic conditions. The results of the simulations are presented.

“…In this paper, a novel and special cooling system design for an axial flux permanent magnet (AFPM) machine is carried out as a case study. In the literature there has been much research on the electromagnetic aspects of AFPM machines, but their thermal performance has not been fully investigated (Mellor et al, 1991;Hendershot and Miller, 1994;Lee et al, 2000;El-Refaie et al, 2004;Boglietti et al, 2005;Mezani et al, 2005;Dorrrell et al, 2006;Trigeol et al, 2006;Yu et al, 2010;Wrobel et al, 2013;Chong et al, 2014;Dong et al, 2014). For other types of electrical machines, there are four methods generally used for thermal analysis.…”

Abstract:Overheating of permanent magnet (PM) machines has become a major technical challenge as it gives rise to magnet demagnetization, degradation of insulation materials, and loss of motor efficiency. This paper proposes a state-of-the-art cooling system for an axial flux permanent magnet (AFPM) machine with the focus on its structural optimization. A computational fluid dynamics (CFD) simulation with thermal consideration has been shown to be an efficient approach in the literature and is thus employed in this work. Meanwhile, a simplified numerical approach to the AFPM machine with complex configuration in 3D consisting of conduction, forced convection, and conjugate heat transfer is taken as a case study. Different simplification methods (including configuration and working conditions) and two optimized fans for forced convection cooling are designed and installed on the AFPM machine and compared to a natural convection cooling system. The results show that the proposed approach is effective for analyzing the thermal performance of a complex AFPM machine and strikes a balance between reasonable simplification, accuracy, and computational resource.

“…The most recent review dealt with an extended survey on the evolution and the modern approaches in the thermal analysis of electrical machines [1]. The journal literatures on thermal analysis of electric motors are [2][3][4][5][6][7], describing induction motors; [8][9][10][11][12][13], dealing with permanent-magnet motors. The thermal analysis of IPMSMs has received less attention than other machines.…”

-This paper reports an investigation of pulse width modulation (PWM) techniques for twophase brushless DC (BLDC) motors fed by a two-phase eight-switch inverter in a fan application. The three-phase BLDC motor is widely applied in industry; however, a lower-cost two-phase BLDC motor and drive circuit has been greatly in demand in recent years. In this paper, we introduce a mathematical model of the two-phase BLDC motor with sinusoidal back electromotive forces (EMFs) based on traditional three-phase BLDC motors. To simplify the drive algorithm and speed up its application, we analyze the principle of block commutation for a two-phase BLDC motor drive in the 180-electricaldegree conduction mode, and we further propose five PWM schemes to improve the commutation performance of the two-phase BLDC drive. The effectiveness of the proposed PWM methods is verified through experiments.
