Re: OT-how to test and repair DC brushed motors.


 

¿ªÔÆÌåÓý

?I used to do a lot of work for the city that I live outside of . Unfortunately sometimes that meant that I had to work on equipment at the sewer ponds & such . Onetime they had put in a new motor tin one of the lift stations hat one of the bosses had bought years before to have for a rainy day . When I got there the wires were all exposed & like a dumb sh** I believed them what I was told it was the exact same motor . Well after some time trying to figure out why it wouldn't run had them pull it which they complained & bitched about . Turned out they bought the? same pump but with a different motor . The voltage was off by @ 200 volts .& the motor could not be re-strapped to run at their lower voltage . They ended up sending the original back for repair & rented a trailer mount pump to keep things running . Me being the nice guy I didn't charge them for all my time , I kinda felt sorry for the guy . M otor shops are gettin to be like shoe repair shops , their just ain't as many as there used to be .

My boss at the laundry always bought new motors when one had problems. Was of some benefit to me as a lot of the ones that weren't absolutely fried followed me home so they wouldn't have to pay to have them hauled away. Only exception was the 60HP 3phase motor. .?

Bill, Just about any starter shop can growl them for you. As far as larger facilities go,? if Ron is still at Capitol Electric, tell him Jeff from Warfield and Chapman said hello.
All the guys i knew at Evans Electric and Southwest Electric are retired or ...really retired...
