Permanent-magnet motors are widely used in-wheel motors of electric vehicles and hybrid vehicles. Based on a movable stator design, this paper presents a new type permanent-magnet motor, whose torque can be adjusted in order to meet different driving requirements. The stator geometry is varied by means of changing movable stator positions. Accordingly, the air-gap length in permanentmagnet moto...

Light urban electric vehicles are an important target, both for the researchers and manufacturers. Concerning the motor’s choice, more ways are investigated, but the most important is that as compact as possible solutions have to be used. In the top of the preferences, the permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) are situated. These are preferred thanks to their...

Original scientific paper The temperature distribution over the cross-section of an induction motor is calculated at the steady state and transient condition. In order to develop smaller and more efficient electric motors, there is a necessity to carry out more thermal analysis in parallel with the traditional electromagnetic design. It has been found that attention to the thermal design can be...

Purpose Herein is reported an application of life cycle analysis (LCA), using the Methodology for the Ecodesign of Energy Using Products (MEEUP), in order to assess the influence of some design parameters in the environmental impact of three-phase induction motors. A motor design procedure to minimize the total environmental impact, based on data obtained from commercial motors, is presented. T...

The micro all-electric vehicle pertaining to this study is rear-driven, with motors in the left and right rear wheels. The motors are brushless dc (BLDC) using Hall effect sensors with a trapezoidal back-electromotive force. The control system is developed by using a digital signal processor. To thoroughly utilize the fast torque generation feature of BLDC motors, direct torque control (DTC) is...

This paper presents an in-depth system-level experimental analysis comparing air-cooled and liquid-cooled commercial off-the-shelf (COTS) electric motors. Typically, liquid-cooled electric motors are reserved for large, expensive, high-end applications where the design of the motor’s electromagnetic components are closely coupled to its cooling system. By applying liquid cooling to a pre-existi...

Electric motors play an important role in consumer and manufacturing industries. Among all different kinds of electric motors, Interior Permanent Magnet Synchronous Motors (IPMSM) have a special place. That is because of their high torque to current ratio, large power to weight ratio, high efficiency, high power factor and robustness. In this paper a radial basis function (RBF) neural network b...
