Development of mine-used flameproof three-phase asynchronous motor with high voltage and high efficiency

  • In view of problems of energy waste and environmental pollution caused by high power consumption and low efficiency of existing motors, a mine-used flameproof three-phase asynchronous motor with high voltage and high efficiency was developed. Development goals, selection of slot matching of stator and rotator, determination of punch size of stator and rotator, main parameters design in electromagnetic calculation, and structure design of the motor were introduced detailedly. Prototype test results show that test values of efficiency of the developed motor are more than the value of energy efficiency grade of 1evel 1 in GB 30254-2013 High Voltage Three-phase Cage Asynchronous Motor Energy Efficiency Limit and Energy Efficiency Level, and at the same time, it can meet design requirements of low noise and low vibration.
