An efficient, speedy, multi-grooved (ESMG) mold was designed and manufactured for optimization to address issues such as low heat transfer rate, slow casting speed, and quality defects in traditional continuous casting molds. The flow resistance mech

The parametrisation of the geometry in shape optimisation has an important influence on the quality of the optimum and the rate of convergence of the optimiser. Refinement studies for the parametrisation are not shown in the literature, as most metho

A conformal cooling channel (CCC) follows the mold core or cavity profile to carry out uniform cooling in the cooling stage. However, the significant pressure drop along the cooling channels is a distinct disadvantage of the CCC. In this study, an in

The study of conformal cooling channel usually has adopted two assumptions in model design: the use of (1) a hot runner system and (2) a one-mold-one-cavity design. These assumptions substantially simplify the research. However, most molds are design

Abstract Permanent magnet synchronous motors (PMSM) have high power density, stable output torque, low noise, and good speed regulation performance, making them very suitable for electric vehicle propulsion. In this paper, a PMSM controller, based on
