西安科技学院和兖州矿业(集团)公司计算中心开展了以鼠笼式感应电动机取代直流电动机作为矿用电力机车牵引动力的研究。我国煤矿使用的(交、直流)架线式和蓄电池式电力机车的牵引电动机都是直流电动机。直流电动机的造价高、可靠性低、电刷和整流子磨损需定期维修、机械强度差,感应电动机具有价格低、可靠性高、体积小、重量轻、机械强度高、坚固耐用、易维
Xi’an Institute of Science and Technology and Yanzhou Mining (Group) Company Computing Center to carry out a squirrel-cage induction motor instead of DC motor as a mining electric locomotive traction power research. China’s coal mines (AC, DC) overhead and battery electric locomotive traction motors are DC motors. DC motor high cost, low reliability, brush and commutator wear and tear need regular maintenance, poor mechanical strength, induction motor with low price, high reliability, small size, light weight, high mechanical strength, durable, easy dimension
