Abstract-This study is concerned with the minimization of cogging torque component, by taking into account magnet thickness and pole embrace value for small power battery-fed brushless DC motors (BLDCMs) with high efficiency and high reliability. Distinct values of magnet thickness and embrace are defined in the specified range for the design and comparatively mentioned in the paper. Depending upon the magnet thickness and pole embrace, the obtained new magnet shapes are modelled on a comparative basis using both analytical approach and finite element analysis (FEA). The BLDCM with low cogging torque and optimal magnet shape is designed by the help of 3D FEA by considering the magnetic flux density distributions. In addition, the magnet shape's effect on the motor parameters such as motor efficiency, output power, and air gap flux density is discussed throughout the paper. The analytical results are verified by the transient FEA.

“…However, dynamic winding reconfiguration may result in torque jolts if the winding inductance is low [21]. Eventually, considering all topologies dual or double-sided machines had has many benefits both in slotless or slotted machines [22,23]. Herein, a new configuration of slotless BLDC motor is introduced.…”

A novel high-torque slotless brushless DC (BLDC) motor is proposed. The proposed topology has a unique concentrated winding structure and accordingly the motor design is effectively modified with its dual-rotor structure. The rotor structure of the proposed motor may be modified itself and form three different topologies. First, the basic structures of the new slotless BLDC motor and its operation principle are described. Then, design methodology of the proposed motor is explained. Initial analysis of the motor is subsequently conducted using 2D finite element (FE) simulations. Next, design parameters of the proposed motor are further optimized using Salp algorithm. The proposed topologies are compared with the conventional single and dual-rotor structures. Finally, experimental prototype is built for verification. The simulation and experimental results exhibit that the proposed slotless BLDC motor has high torque and efficiency in comparison with the conventional structures and may be a good candidate for small-sized BLDC motors. Moreover, the results show that the proposed BLDC motor has nearly ideal back-EMF which makes sensorless methods more efficient for the proposed motor.
