电动吸引器的常见故障是起动绕组烧损。该起动绕组由四组绕成,每组有三只线圈绕成同心式,中间一只线圈的匝数约为内外二只线圈匝数之和。起动绕组重绕时,一般采用两种方法:一是采用本模绕制线圈,然后置入定子槽内;二是直接绕入定子槽内。前者需按电机型号配做木模,后者则效率较低。实践证明,这两种方法都有可改进之处。 Electric vacuum suction device is the common fault burning start winding. The starting winding is made up of four groups, each group has three coils wound concentrically, and the number of turns of one coil in the middle is the sum of the turns of two coils inside and outside. Winding winding rewinding, the general method of using two methods: First, the use of this model winding coil, and then placed in the stator slot; the second is directly wound into the stator slot. The former needs to be made according to the motor model wooden mold, which is less efficient. Practice has proved that both methods can be improved.
