录像机下磁鼓损坏较少,损坏的主要原因是有些人似懂非懂,在拆上鼓时把下磁鼓拆坏。从坏的情况看有两种:一是撬坏下鼓鼓体,这种情况只有换新。二是拉断旋转变压器的引出线,且拉断部位多在旋转变压器下部转角处,外部无法连接,这种情况可修复利用。原因是买一原配下鼓组件一是价格昂贵,二是难于购到。下面以富丽3000HCMKⅢ机为例,谈谈修复体会。从机上取下磁鼓组件,先拆去上鼓,然后把鼓电机转子拆下来,再拧下三颗螺钉后取下定子组件。拆转子时一定要注意看清原装配位置,这在驱动集成块为BA6462FP时更是如此,而在KA8310为驱动集成块
Less damage to the drum under the recorder, the main reason for damage is that some people know it, in the demolition of the drum next drum disassembled. From the bad situation there are two: First, pry bad drum under the drum body, this situation only for new. The second is pulled off the rotary transformer pinout, and pulled off more than the corner of the lower part of the resolver, the external can not connect, this situation can be repaired. The reason is to buy a drum kit with the original one is expensive, the second is difficult to buy. The following to the rich 3000HCMK Ⅲ machine, for example, talk about repair experience. Remove the drum assembly from the machine, remove the drum first, and then remove the drum motor rotor, and then unscrew the three screws and remove the stator assembly. When demolishing the rotor must pay attention to see the original assembly position, which is even more so in the drive manifold for the BA6462FP, and KA8310 for the drive manifold
