- Abstract
- Owing to the importance of environmental issues, a prevalent global challenge, the use of permanent magnet synchronous motors has increased significantly in several industries. Motor efficiency is important because of environmental regulations. As an approach to increasing the efficiency of a motor, a method has been presented to increase efficiency via a motor design. Although the design is important, the method for controlling the actually developed motor also significantly affects efficiency. As a method for controlling the existing motor, current control was adopted. Speed-torque control is widely used as a method commonly adopted in conventional motor control. As the motor control method proposed in this study, flux-torque control was employed. Although flux-torque control is not a novel technology, in the case of the control method proposed in this study, a method for interpolating values after comparison with actual data via the finite element analysis (FEA) of the motor is applied. In this study, a method for interpolating inductance among important factors for motor torque control is proposed. Therefore, regarding the proposed flux-torque control, the validity of the study was verified based on the actual data obtained from the FEA and actual manufactured motor shape. IEEE
