When we checked the working of the servomotor before repairing it, our engineers detected a problem in the front cover where the bearing is, because the shaft rotated irregularly, as you can see in this video.<\/p>\n<\/div>[vc_video link=”https:\/\/www.youtube.com\/watch?v=DvS3-w0Scmk” el_width=”80″ align=”center”]

Once the servomotor had been disassembled, we could analyse its condition. The front cover housing was in good condition. However, the bearing was without lubricant and with serious damage in the bearing cage. In addition, we saw the typical iron dust contamination (rusty colour) inside the motor due to the broken bearing.<\/p>\n<\/div>

Having received two motors from the same customer with the same problem, we requested information about how the motors were working to be able to find out the reason for their poor condition.<\/p>\n

The answer was that they worked in a place that required a pulley and belt. If the tension of the latter is inappropriate the servomotor\u2019s front cover, is overworked and causes the bearing to break as in this case. One way of preventing this problem is to check the pulleys\u2019 tension.<\/p>\n
