  • Sweep motor humming

    I have a sweep motor that is humming and not running. I have switched out motors and chassis and still does same. Contactor engages but nothing

    Could be a few things. Check your C2 plug, capacitors, sweep run and sweep reverse switches and voltage to the plug.

      The voltage to the plug seems to be shorting out and is not like the table plug. I also found paper shavings in the wire way by the caps. I didn't find any that we're blown though?

        When it comes to front end motors, Swap Chassis, motor then caps. Double check the wires on the TS's. Also check on the C1 at the 21 22 23 and 24 connections. It sounds like your start windings are not fully on line.

          This lane was running and had not recorded a problem for months so all of a sudden it started popping the breaker in the breaker panel and now this motor problem

            I would lean toward the sweep rev. switch. Could an off spot on the lane have started the issue? I have found the paper in the wireway also from past blowouts. ( If the motor tries both ways at the same time the wall breaker will blow)

              Try swapping the stator with a good known working one and see if it works, if it works then most likely starter switch (if your using SS) is wired wrong and/or the the run winding are fighting against one another. To me this sounds like the starter is not kicking in.

                Switch the sweep and table capacitors with each other, if the table wont run its the capacitors, or if you have combo motors just plug the table plug into the sweep and run the table contactor. Being that you changed the chassis and motor, my bet its the capacitors or a cenfrifugal switch.

                  I did plug the table plug into the sweep motor and runs fine. Took the sweep plug and plugged in the table motor and will not run

                    Change the sweep capacitors

                      swap the table and sweep capacitors with eachother to see if its the capacitors, or just change the sweep capacitors with new ones. Its probably the capacitors, they aid in stopping and starting the motor

                        If the motor will run on the table cable then you either have a broken wire in your sweep cable or a bad capacitor or bad sweep reverse switch.

                          Changed out the sweep caps with the table caps and still same result. Motor humming

                            I would suggest opening up the front wireway of your trouble machine and it's neighbor to compare with, trace each of the 5 sweep plug wires and check to make sure nothing's become disconnected, also checking for broken wires or wires they have become brittle due to excess heat and aren't conducting electricity like they should. I've accidently popped wires off for one of the motor circuits countless times when fiddling around in the wireway having the motor do nothing but hum.

                              Well well. 1 there was a wire disconnected from the sweep reverse switch and also pin 27 was fried Thanks for the help
