起动电机的整流子与矩形导线的接头处是用锡焊接的.使用中因起动时间过长,造成电机过热,会使焊锡处熔化脱焊,形成接触不良故障,使起动电机出现不转、旋转无力、烧毁整流子等现象. 要修复该处脱焊,需要用足够大功率的电烙铁,但一般社队拖拉机站往往由于缺少大烙铁,不得不将起动电机送往它处修理,或勉强用小功率烙铁焊修,虽经修复,仍有“假焊”之处,使用时间不长,故障现象又重复出现.为解决这个问题,我们用以下土方法,不用大烙铁,即可将脱焊处重新焊好.
Starter motor commutator and rectangular wire connector is soldered with tin. In use because of the start-up time is too long, causing the motor overheating, the solder will melt off the solder, the formation of poor contact failure, so that the starter motor does not turn, rotate Weakness, burnout commutator, etc. To repair the problem of desoldering, electric iron of sufficient power needs to be used, but in general, the community commuter tractor station often has to take the starter motor for repairs or barely because of the lack of a large soldering iron Low-power iron welding repair, though the repair, there are still To solve this problem, we use the following earth method, without a large iron, you can Desoldering Department re-welding good.
