According to features of circuit breaker operating mechanism,motor design methods were introduced from aspects of improving electrical power density,mechanical properties and servo performances.

Providing the fast and effective query functions for motor design through system-structured platform in implementation of the enterpise resources planning system is introduced.

In this paper,the functions in motor design are repeatedly utilized with the dynamic link library (DLL) independent of programming environment.

The new idea overcomes the defects in traditional method and is easily understood by the learners especially the apprentices of electrical machine design.
