Abstract: Robust design method for a textile-manufacturing-dedicated multiphase asynchronous motor, including the steps: designing a motor with design variables for a high-efficient, energy-saving, multiphase asynchronous motor; selecting a number of controllable variables and their level values to build an inner orthogonal table; selecting a number of noise factors and their level values to build an outer orthogonal table; using a Taguchi method, determining the optimal combination of level values of the controllable variables and corresponding values ranges for a tolerance design, resulting in an optimal design scheme; producing technical drawings for each parts of the motor according to the optimal design scheme and producing a physical motor; comparing the performance of the physical motor with the predetermined performance target and repeating the above steps as many times as necessary until the performance target is met and the motor achieves the optimal balance between the quality and cost.
