“…Depending on the current density, losses and slot area constraints, the winding resistance cannot be made higher than a certain limit. Using all-teeth-wound winding topology is causing a lower value of winding inductance while alternate-teeth-wound structure results in higher winding inductance [27]. In this study, the application requires a fast acting, dynamic force production to simulate the mentioned earthquake movements.…”

The progress in material and manufacturing technologies enables the emergence of new research areas in electromagnetic actuator applications. Permanent magnet (PM) linear motors are preferred to achieve precise position control and to meet the need for high dynamic forces in the seismic shake tables that are used in analyzing reactions of structure models. The design approaches on the linear motors used in the seismic shake tables may vary depending on the desired force, stroke and acceleration values. Especially, the maximum width, the maximum depth, the maximum linear motor length in longitudinal direction and the maximum travelling distance parameters are the primary design criteria in seismic shake table drive systems. In this paper, a design approach for a linear PM brushless direct current (BLDC) motor with high force/volume, force/weight and force/input power ratios is developed. The design was analyzed using two-dimensional (2D) and three-dimensional (3D) finite element method (FEM) approaches through the ANSYS Maxwell software. The mathematically designed linear BLDC motor was manufactured and subjected to displacement, acceleration and force tests that are used in seismic analyses. The results of the experimental tests validate the convenience of the proposed design approach and the selected parameters.

“…After the required motor data are calculated, analytical calculations are made for the motor design. As an electric motor, a subfractional slot winding BLDC motor type is selected due to its higher efficiency, easy manufacturing, and lower cogging torque [18][19][20][21]. The motor chosen is an inner rotor outer stator BLDC motor with a 12-slot/10-magnet combination [22][23][24].…”

Electric motor and power electronic systems are essential elements for the performance and efficiency of electric vehicles (EVs) and hybrid electric vehicles. The inadequacy of the range due to battery limitations is compensated by powertrain solutions and innovative control algorithms. Future targets of electric powertrains are mostly based on weight, space, and efficiency issues. Highly efficient low-volume and lightweight propulsion systems increase the performance of EVs and also enhance their importance as an alternative to internal combustion engine vehicles. In this paper, a detailed propulsion system design study is presented by considering all of the important constraints of the electric powertrain. The design criteria and output, which are opposites of each other, are submitted in terms of their advantages and disadvantages. The tests of all constraints are conducted as a whole and discretely and then the effects of electrical machine and power electronics circuits are presented.

The study covers the design, analysis and experimental study of a 1 kW motor which is designed for a special in-wheel motor driven light electric vehicle. The main concern is to design a BLDC motor having a higher value direct-axis phase inductance which is providing high performance field weakening operation. A sub-fractional slot concentrated winding structure with unequal tooth widths is chosen. The design phase is including the motivation and the computer aided design works. A software package based on configurator approach is used to determine the motor parameters in a broad sense. Then the motor is modeled in a Finite Element Analysis (FEA) package for detailed analysis and, particularly the 2D and 3D field analyses are obtained to verify winding inductance value. The designed motor is manufactured precisely and an experimental study is held to verify the design work including the precise measurement efforts for the motor inductance. Also the field weakening operation of the motor is managed by using phase current advance method. Index Terms-Brushless DC motor, field weakening operation, winding inductance
