This paper describes the design and modelling of a DC linear stepper motor (DLSM), to investigate the air-gap magnetic flux density and the static features of the thrust force under the DC current excitation condition, while taking the nonlinear properties of iron materials used into account. A Finite Element Method (FEM) study utilizing software called a “MagNet” was employed to model and construct a linear DC motor. The thrust force, air-gap flux density, and static thrust force at various airgaps were compared in simulation and real time. The result showed that the magnetic flux density presents a sinusoidal shape in both the simulation and measurement, where the peak error value was around 7.14%. A comparison was made with thrust force, as the armature current has different values; the results show that the difference between the experimental and computed peak value was 8.07%, while the error between the measured and simulated value was 5.02% when the thrust force was measured at different air gap lengths.

This study is concerned with the reduction of ripple in the thrust force produced in a linear Brushless Direct Current Motor (BLDC). To reduce the ripples in the generated thrust force, different methods such as structural solutions are applied both in the control part and in the production phase of the motor. In this study, skew application, which is one of the mechanical methods, is proposed. For this reason, the changes in the thrust force of a BLDC motor with a surface magnet-placed translator are investigated by applying different levels of skew to the magnets. First, a 3D solid model of the motor was created. A pole on the translator of the linear BLDC motor is composed of 3 equal magnet groups. For each skew level, the magnets were shifted 3 mm independently of each other and the thrust force values were examined. For this process, a 3D magnetostatic analysis of the linear BLDC motor was performed. The results obtained show that the skewing process applied to the magnets reduces the ripples in the thrust curve up to a certain point, after which no significant improvement in the ripple is observed, while the average force value decreases significantly.

“…Metaheuristic approaches have shown to reach an approximate optimal solution with a population of individuals evolving toward the global best solution of the fitness function. More and more successful applications have been reported in solving engineering design problems in recent years, [11][12][13][14][15][16][17][18] including the optimal design of BLDC motors and electromagnetic actuators. For example, Potnuru et al 19 presented a new developed nature-inspired flower pollination algorithm to design the speed control of BLDC motor with optimal PID tuning and successfully demonstrated its effectiveness by comparing with other methods.…”

Many optimal design problems in the engineering field are nonlinear, multivariate, mixed integer, multimodal, and constrained. Meta-heuristic approaches have been widely used to solve these complex problems, but most of them are often sensitive to the settings of tuning parameters for different optimization problems, and suffer from premature convergence during the evolution process. This article proposes a novel hybrid teaching-learning-based optimization (HTLBO) algorithm to tackle this problem. A comprehensive teaching-learning mechanism with no adjustable parameters is introduced to improve the global optimal solution while in the meantime maintaining the solution diversity. The performance of the proposed HTLBO is tested on nine unconstrained benchmark functions and two nonlinear constrained benchmark functions with integer variables. Then the algorithm is applied to solve two significant electromagnetic design problems, that is, optimal brushless direct-current (BLDC) motor design and electromagnetic actuator geometric construction design. Simulation results on both the benchmark functions and practical engineering design problems confirm the efficiency and robustness of the proposed algorithm.
