“…This approach was undertaken with the objective of improving torque density performance and maintaining low torque ripple over a wide range of current densities [12]. Also, Muhammed Muhsin Coşdu et al used a multiobjective differential evolutionary optimization algorithm (MODE) on an external rotor PMSM hub motor for the "Efficiency Challenge" competition to determine its lightweight potential [13]. Christian A. Rivera et al found that the application of banana-shaped magnets can improve motor performance for the same magnet weight [14].…”

This study investigates the design an electric motor propelling hubless wheel mounted on an electric bicycle (e-bike) by numerical analysis. The motor is part of an in-wheel system that uses a permanent magnet synchronous motor (PMSM) to drive the hubless wheel. This paper presents an optimized PMSM design and compares various torque-related parameters, such as cogging torque, cogging torque total harmonic distortion (THD), and ripple torque. The comparison is based on a motor design that examines the effect of different factors, including the number of windings, slot openings, permanent magnet span, and magnet thickness. The motor was modeled and analyzed with variations in the number of windings (21, 23, 25), slot openings (2.4 mm, 3.0 mm, 3.6 mm), permanent magnet span (23 mm, 25 mm, 27 mm), and permanent magnet thickness (3.5 mm, 4.0 mm, 4.5 mm). Our findings suggest that increasing the permanent magnet’s thickness leads to a higher magnetic flux density. Additionally, when the permanent magnet span exceeds 25 mm, there is a sharp increase in cogging torque THD. Based on these results, a slot opening of 3.0 mm and the use of 25 windings are considered suitable for a hubless e-bike.

“…Numerical methods based on the finite element method allow obtaining the most detailed and accurate picture. These methods make it possible to perform calculations of a steady-state or transient process in a three-dimensional problem statement and to determine parameters in any part of the motor [3][4][5][6][7].…”

The paper is devoted to finding the set value of the torque of an electromechanical energy converter with a solid rotor by solving an optimization problem in the Optimetrics module of the Ansys Maxwell software. A feature of the material described in the paper is the simultaneous optimization solution using the Sequential Nonlinear Programming (Gradient) algorithm and the solution of the field problem using the finite element method to determine the torque at each step of the iteration. The paper describes in detail the setting of the research tasks, the basic model of the electromechanical energy converter with a solid rotor in Ansys Maxwell 2D, the settings of the Optimetrics module, the task of the objective function and varied parameters, the convergence task with respect to the magnitude of the rotation torque, and the derivation and analysis of the results obtained during the optimization. The techniques described in this paper can be applied to any other type of electric machines.
