Abstract

The invention relates to a method for designing a single-phase asynchronous machine based on a multi-target hybrid simulated annealing algorithm, comprising the following steps of: determining variables to be optimized, and establishing a chromosome and a population; setting the initial temperature of the simulated annealing process to be T0, and presetting iteration generation thresholds of the population; evaluating all chromosomes in the current population; setting satisfactory solution expected values, and searching the satisfactory solution; disturbing the population to accept or reject the chromosome; acquiring the number of the chromosomes in the current population, and randomly generating the chromosome to form the new population; searching non-inferior sets by taking the new population as the current population; and annealing in segments. The method is low in experience dependence degree to engineers, short in design period, low in design cost, simple in design process operation, and easy in promotion.

Description

technical field [0001] The invention relates to a design method of a single-phase asynchronous motor. technical background [0002] Single-phase asynchronous motors with a large volume and a wide range are the largest energy consumers. The problem of energy saving is a serious issue facing the motor industry. The formulation and implementation of mandatory energy efficiency standards for motors provides new opportunities and challenges for the development of the motor industry. . The optimal design of single-phase asynchronous motor is the most critical link to improve the energy efficiency of the motor. If the efficiency of the motor is increased by an average of one percentage point, more than 2 billion kWh of electricity can be saved a year. Therefore, improving the design level of single-phase motors is an important aspect of energy saving in industrial terminal equipment. [0003] The design method of the traditional single-phase asynchronous motor is: start with the ...
