With the aim of enhancing the reliability of explosion-proof motors for under- ground mines and improving the starting performance of a motor the paper studies in depth the optimum design of asynchronous motor.Three optimization methods, namely,Hooke-Jeeves modular vector search method,Powell conjugate direction search method,and random direction search method,have been chosen and improved.And three programs are given.Practice shows that optimum design of motor can be quickly obtained by using these programs and the value of objective function can be ge...
