“…Additionally, examining the studies on outer-rotor PMSM from the literature reveals a predominant focus on surface-mounted structures [10][11][12][13]. When examining outer-rotor PMSM, it is observed that these motors effectively meet the demand for high torque at low speeds and are suitable for direct drive applications.…”

Permanent magnet synchronous motors (PMSMs) are consciously used as traction motors in electric vehicles (EVs) and hybrid electric vehicles (HEVs). The rotor position (inner-rotor, outer-rotor) and topology of PMSMs significantly impact their torque profile, efficiency, and demagnetization characteristics. This article focuses on designing an outer-rotor permanent-magnet-assisted synchronous reluctance motor (PMaSynRM) under traction motor requirements and investigating its electromagnetic performance using the finite element method (FEM). This study's primary challenge is achieving optimal machine performance, considering high maximum torque and the risk of demagnetization at low levels. The design, derived from analytical calculations, was subjected to Finite Element Method (FEM) analyses. These analyses investigated motor performance in terms of efficiency, the ability to generate torque at different drive currents, and the risk of demagnetization. As a result of the study, the proposed PMaSynRM design was obtained that provides an adequate demagnetization performance even under 300% loading, has a maximum torque exceeding 35 Nm, and achieves an efficiency of 90% at rated conditions.

“…As a result, more heat losses will generate. Other than that, the optimization problems which always include a coupled thermal-electromagnetic problem are becoming common increasingly between engineers and designers of the machines [2][3]. Hence, the heat transfer in the small DC motor needs to understand.…”

The heating of brush DC motor in the various applications usually involves the thermal damage to the motor like demagnetization of the magnet and also leads to short circuit. Due to this problem, the temperatures at the sensitive components are needed to be observed for a different number of loads. So, the motor will be delivered some torque when running thus generating the different value of losses. In this paper, a healthy brush DC motor is being used to observed temperature rise from the brush through the motors’ component and lastly to the outer space of the motor. Hence, discussion on the pattern of temperature rise will be discussed.
