“…Two new construction methods are available: the self-bond type[8] and the dot-bond type [9][10]. The selfbond type that after applying the adhesive sheet to the plate, it is attached to the counterpart and involves bonding the motor core by applying heat during the post-production process [11]. This is achieved by initially applying a bond coating to the raw materials.…”

The global electric vehicle market is experiencing rapid development, with three core technologies driving this growth: batteries, driving motors, and platforms. Specifically, recent research has focused on the material trends and manufacturing characteristics of driving motors. A driving motor is responsible for converting electrical energy into kinetic energy and transmitting power, and its performance is categorized as either high-output or low-output based on the vehicle's requirements. Key factors that impact the output of driving motors include the size of the motor core, the magnet shape, and the material thickness, with the material being the most important factor related to performance improvements. As a result, specialized technologies for manufacturing driving motors are gaining traction, including the use of thin steel plate materials. This shift in manufacturing methods has been implemented to enhance the performance of the motor. To serve as the driving motor steel plate material, a thin steel plate material with a thickness of 0.2 ~ 0.25T was utilized, and the method of laminating by embossing, which enhances the lamination force, was replaced with adhesive lamination utilizing a bond. Two adhesive lamination methods were employed: the dot bond and the self-bond types. The dot-bond type involves creating bonds at several points on the motor core, while the self-bond type employs bond-coated steel plate materials for lamination. Prior to incorporating the new self-bond steel plate material into the mass production line, a study of the manufacturing facility conditions and manufacturing characteristics was conducted.

In the present study, simple models were proposed to predict the capillary-driven flow length in a surfactantadded poly(dimethylsiloxane) (PDMS) rectangular microchannel. Owing to the hydrophobic nature of PDMS, it is difficult to transport water in a conventional PDMS microchannel by means of the capillary force alone. To overcome this problem, microchannels with a hydrophilic surface were fabricated using surfactant-added PDMS. By measuring the contact angle change on the surfactant-added PDMS surface, the behavior was investigated to establish a simple model. In order to predict the filling length induced by the capillary force, the Washburn equation was modified in the present study. From the investigation, it was found that the initial rate-of-change of the contact angle affected the filling length. Simple models were developed for three representative cases, and these can be useful tools in designing microfluidic manufacturing techniques including MIcroMolding In Capillaries (MIMIC).
