我厂1982年起开始了SS4型电力机车所用ZQ850牵引电动机的设计与试制工作,截至1986年已经试制成功三台SS_4型电力机车的电机,目前该型电力机车正在进行试运行。 1982年ZQ850脉流牵引电动机方案设计时,首先研究了六极87槽、99槽与117槽的各种电压电流方案,在取长补短,综合比较各方案优缺点的基础上,最后选定了六极93槽,虚槽数为4的方案,其基本参数如下: 电机额定功率(持续制)800KW; 电机额定电压1010V; 机车额定牵引力约为431.49×10~3N; 机车额定速度约52Km/h; 机车最大速度100Km/h; 机车动轮直径1.25m 保持800KW的恒功率速度比≮1.4;
Our factory started the design and trial work of ZQ850 traction motor used in SS4 electric locomotive since 1982, and as of 1986, it successfully trialled the electric motor of three SS_4 electric locomotives. At present, this type of electric locomotive is under trial operation. In 1982 ZQ850 pulse traction motor design, the first study of the six-pole 87 slots, 99 slots and 117 slots of various voltage and current programs, learn from each other, comprehensive comparison of the advantages and disadvantages of each program based on the final selection of the six-pole 93 slot, the number of virtual slots for the program 4, the basic parameters are as follows: motor rated power (continuous system) 800KW; motor rated voltage 1010V; locomotive rated traction is about 431.49 × 10 ~ 3N; locomotive rated speed of about 52Km / h; locomotive The maximum speed of 100Km / h; Locomotive wheel diameter 1.25m to maintain constant power 800KW speed ratio ≮ 1.4;
