据专家介绍,中国家用电器研究所已研制出大、中、小惯量系列铁氧体和钕铁硼永磁宽调速交直流伺服电动机,并已投入批量生产。该电机克服了国外某些同类产品电流大、温升高、电机槽数和整流片数无法匹配、存在“死元件”,以及波动大、影响低速性能等弊端,在技术、性能和功效等方面达到了新的水平。 According to experts, China Household Electrical Appliances Research Institute has developed large-, medium-, and small-inertia series of ferrite and NdFeB permanent magnet wide-speed AC-DC servo motors and has been put into mass production. The motor overcomes the disadvantages of some current foreign products such as large current, high temperature, inconsistent number of motor slots and number of rectifying pieces, existence of “dead components”, and large fluctuations, which affect low-speed performance, etc., in terms of technology, performance and efficacy, etc. Reached a new level.
