本人近日接修一中南牌便携式录放机,正面朝上时放音正常,正面朝下则停机。经反复检查发现问题出在电机内:其转子和两端机壳间出一了近lmm的间隙。转子在间隙内能沿轴向跑动。当机身正面朝上,转子落在原位,运转正常。当机身向下,转子落向前方,与电机前壳接触摩擦,即出现卡壳停机故障。因电机包封难拆,一般谁修都要换电机。本人则用一根长3cm、直径约0.5mm的小钢丝解决了问题。方法是将钢丝制成弯曲勾形(可将小弹簧拉直代用)参看图1,一头
Recently, I took a South Zhongnan portable video recorder, positive play upright, down front down. After repeated inspection found that the problem lies in the motor: the rotor and the shell between the two ends of a nearly lmm gap. The rotor can run axially in the gap. When the fuselage face up, the rotor fell in place, functioning properly. When the fuselage down, the rotor fell forward, contact with the motor front shell friction, that card failure occurs. Because the motor is difficult to remove the envelope, the general repair who have to change the motor. I use a long 3cm, diameter of about 0.5mm small wire to solve the problem. Method is to make curved steel wire hook shape (small spring can straighten out) see Figure 1, a
