A Design Procedure for the Applications-Specific Electric Motors

Abstract

A design procedure for the Applications-Specific Electric Motors (ASEM) is proposed. The proposed design procedure is relevant to the design of the permanent magnet synchronous motor which fulfills required typical operating points under the restrictions of dimensions and the power source conditions. The design procedure is composed of two stages, a rough design and an accurate design. A rough design finds a permissible area of the combination of motor constants which satisfy the given typical operating points under the given power source conditions. According to the obtained permissible area of motor constants, an accurate design achieves the detailed motor design determining the dimensions, the winding specifications and constituent materials. Among several designed motors, one with highest fitness from standpoints of high efficiency, manufacturability and cost is finally selected. The experimental studies show that the designed motor using the proposed procedure satisfies the requirements in the target application.
