卷帘门电机换向器的结构
Structure of motor commutator for rolling shutter door
换向器主要由云母片、换向片组成。
The commutator is mainly composed of mica sheet and commutator sheet.
卷帘门电机换向器接地
Grounding of motor commutator for rolling shutter door
卷帘门电机换向器接地又称换向器对地击穿,是指换向器的换向片与压圈或套筒相通。
The grounding of motor commutator of rolling shutter, also known as ground breakdown of commutator, means that the commutator's commutator sheet is connected with the pressing ring or sleeve.
在换向德上若有两片以上的换向片接地,便会引起电枢绕组短路,使电枢发热,甚至焚毁线圈。此外,电刷会发生强烈的换向火花.因而,及时查看出换向器接地点,并且必须及时进行修补.
If more than two pieces of commutator are grounded on the commutator, it will cause short circuit of armature winding, heat the armature and even burn the coil. In addition, a strong commutation spark will occur in the brush. Therefore, the grounding point of the commutator should be checked in time and repaired in time.
引起换向器接地的主要原因有:换向片V形云母环外露部分积存导电粉尘、汹泥,使换向片与铁套筒或转轴衔接,对炮击穿,v形云母环的3°面缝隙有脏物、金属屑或炭粉,使换向片在电压效果下击穿V形云母环,然后引起接地.
The main reasons for the grounding of the commutator are as follows: the exposed part of the V-shaped mica ring of the commutator sheet accumulates conductive dust and turbulent mud, which connects the commutator sheet with the iron sleeve or rotating shaft, breaks through the gun, dirt, metal chips or carbon powder are found in the 3-degree gap of the V-shaped mica ring, so that the commutator sheet breaks through the V-shaped mica ring under voltage effect, and then causes grounding.
通常用校验灯法来查看换向器是否接地2将220V、60W灯泡串在电枢转袖和换向器之间,使灯泡一端固定在转输上,另一端在换向器上移动,逐片试验,灯泡不亮的换向片则表明没有接地z灯泡发亮的换向片表明接地。

Usually, the method of checking lamp is used to check whether the commutator is grounded. 2. The 220 V and 60 W bulbs are strung between the armature sleeve and the commutator, so that one end of the bulb is fixed on the transfer and the other end is moved on the commutator. Piece-by-piece test shows that the commutator without the earthed Z bulb is grounded, indicating that the commutator is grounded.

卷帘门电机替换片间云母顷刻用上述办法仍不能消除片间短路,则只能替换片间云母片.替换片间云母片的办法如下.
The method mentioned above can not eliminate the short circuit between sheets, but can only replace the mica sheets between sheets. The method of replacing the mica sheets between sheets is as follows.
把上述拆开的换向片组放在平板上,在发生毛病的换向片间做好符号,再用橡胶圈把它箍紧,然后撤除钢丝箍或无纬玻璃丝,用磨成锋口的宽锯条的一段刺进毛病片间。
Put the dismantled reversing sheet group on the flat plate, make symbols between the defective reversing sheets, tighten it with rubber ring, then remove the steel hoop or weft-free glass wire, and pierce the defective sheets with a section of a wide saw blade ground into a sharp edge.
松动后抽出有毛病的换向片,并且刺进与毛病换向片同一规格的新换向片,换向片换好后,再用铁箍(内垫厚纸板)将换向片组箍紧。
After loosening, the faulty commutator piece is pulled out and pierced into the new commutator piece of the same specification as the faulty commutator piece. After the commutator piece is replaced, the commutator piece group is tightened with iron hoop (inner padded thick cardboard).
把换向片组加热到1650C士50C.拧紧螺钉做第一次箍紧,冷却后用校验灯查看片间短路毛病是否已经消除。若未消除,贝IJ应细心寻找毛病原因或重复上述作业;若已消除片间短路则进行装配。
Heat the reversing sheet group to 1650C. Tighten the screw for the first time. After cooling, check the lamp to see if the short circuit between the sheets has been eliminated. If not eliminated, BeiIJ should carefully find the cause of hair pathogens or repeat the above operations; if the inter-chip short circuit has been eliminated, assembly will be carried out.
