摘要
简要介绍了研制的符合尼玛标准的防爆超高效三相异步电动机的主要技术参数与结构设计特点。该电机采用优质硅钢片与退火工艺降低铁耗、低谐波绕组降低铜耗、特殊转子表面加工和酸洗工艺降低杂耗等。同时介绍了UL的防爆规范。
The NEMA premium three-phase explosion proof asynchronous motor＇s research,fundamental parameters,structure,and key technique were introduced.For example,stator and rotor cores were laminated with high-class electrical silicon steel sheets with high permeability and annealing process to reduce iron loss.Low harmonic winding was used to reduce stator copper loss.Rotor surface was lathed with special technology and acid washing to reduce stray loss,etc.Then it showed UL classifications,groups and divisions.
