INTERACTIVE COMPUTER-AIDED-DESIGN OF PERMANENT-MAGNET DC MOTORS

A summary of the design theory associated with dc commutator motors is presented, This is followed by a detailed description of a Computer A ided Design program written specifically for this class of motor. The software engineering content is extremely important: Once the engineer ing design equations are developed and validated, the productivity of the design engineer depends critically on the efficiency and user-frie ndliness of the software itself, The program described in the main tex t permits the integration bf the motor design with the design of the e lectronic controller, together with the simulation of the whole system , When sizing motors for a particular application, speed of execution and the flexibility to evaluate a wide range of design options and par ameter variations are essential, while absolute accuracy is only of se condary importance.
