Robustness design method for textile-manufacturing-dedicated, high-efficiency, energy-saving, polyphase induction motor

A robustness design method for a textile-manufacturing-dedicated, high-efficiency, energy-saving, polyphase induction motor: determining a motor; determining a designing method; determining design variables of the high-efficiency, energy-saving, polyphase induction motor, establishing respectively various indicator mathematical models, constituting a multi-indicator robustness design model; establishing a controllable factor level table, selecting an appropriate orthogonal table on the basis of the number of optimization variables and of the number of states of each variable, constructing an inner orthogonal table to perform an inner design; constructing an outer orthogonal table to perform an outer design; calculating an output characteristic value and the signal-to-noise ratio of a trial solution determined by the inner and outer orthogonal tables; determining an optimal parameter set; performing a tolerance design; drawing blueprints of various parts of the textile-manufacturing-dedicated, high-efficiency, energy-saving, polyphase induction motor on the basis of an optimal design solution, wire-cutting a mold, which is then die-formed, stacked, wound, coil-embedded, paint-immersed, and assembled. The present invention combines the actual operating characteristics of textile-manufacturing-dedicated motors, is capable of acquiring the high-efficiency, energy-saving, polyphase induction motor that is of stable performances, reliable operations, and reduced costs, thus achieving the optimal balance between quality and costs, and improving the market competitiveness of a product.
