电动机在使用中往往会由于过载、短路和缺相等原因造成电动机定子绕组烧坏,这时,就需要对定子绕组进行更换。修理质量的好坏直接影响着电动机运行的性能和使用寿命,本文就如何提高修理质量谈谈定子绕组更换修理的步骤和修理过程中的注意事项。 1.记录原始数据在旧绕组的拆除过程中,除电动机铭牌上所规定的数据外,还应记录下列数据:定子铁心槽数、线圈节距、接线方式、线圈匝数、每槽导线数、导线并绕根数、导线规格、线圈尺寸、并联路数和引出线相对位
The motor is often in use due to overload, short circuit and lack of reason caused by the motor stator winding burnout, then, you need to replace the stator winding. The quality of the repair has a direct impact on the performance and service life of the motor. In this paper, how to improve the quality of the repair of the stator winding repair procedures and repair matters needing attention. 1. Record Raw Data During the removal of the old windings, in addition to the data specified on the motor nameplate, the following data should also be recorded: the number of slots in the stator core, the pitch of the coils, the type of wiring, the number of turns in the coil, the number of conductors per slot, Wire and around the root number, wire size, coil size, the number of parallel and pinout relative position
