I have a 2HP 2 speed Ultra Jet pump for my newly acquired but used hot tub that just hums. Most of the electric motor failures occur at the start up. Excessive motor shaft end play which is caused by worn out motor shaft fiber washers will prevent the centrifugal switch contacts from closing all the way. Worn contacts on the start switch may need to be cleaned or resurfaced with fine sandpaper. if the start windings are not burnt smelling you should still be ok. the contacts for the switch are usually on the back of the terminal board which is usually fastened to the end bell. The centrifugal start switch contacts may not be closing which will cause the motor to hum and not start or be hard to start. The power cable is about 100 feet away, could it be I need a bigger wire? Application: Testing an Electric Motor. I have a 1 hp 3450rpm Hayward pool pump made by A.O. the belt should be firm, but not too tight. March 3, 2009. the switch usually does not need freeing up, it needs it's contacts cleaning. The wiring between the circuit outlet or connection must be adequately sized with the same gauge wire as the required circuit or the electrical current will not be supplied to the motor. Capacitors may be discharged an tested for fault. Electric motors should be installed very carefully and should be looked after at regular intervals. Common Problems with Electric Motors and Capacitor Start Motors, How to Check an Electric Motor, Diagnostic Checks You Can Make When an Electric Motor Will Not Start. You can also learn about motor rewinding and motor rewinding advantages on our website.. Damaged wiring. Run-Start Capacitors. ...

Dave, Electrical Questions and Electrical Answers, Electric Dryer Circuit Troubleshooting Checklist. Put the motor together with the switch wedged closed and energize the motor for about a second. Types of Electrical Testers You may have a separate "choke" button instead of a "push-to-choke" key switch. Make sure the intake air filter is clean, replace as needed. Anything else you can think of for me to test/replace before I give up and buy a new motor/pump? 6.5A. You are likely talking about a single phase electric motor driven fan. Dave. I was able to coat the wire with an insulating liquid and push it out of the way. I found this post really very helpful and this can be a good project for my high school students. there might be something stopping the contacts from closing. Each motor has its own stop and start control as well as a single emergency stop which needs to stop both motors. Be sure the circuit voltage and amperage rating is correct for the unit or motor, and the motor is correct for the application or equipment. Also make sure that the pump is spinning freely and without restrictions as this will effect the operation of the motor as well. I hope this helps you get your motor started, Electric motor starting & run capacitor troubleshooting FAQs Questions & Answers about Electric Motor Start-Boost or Run Capacitors Capacitors are electric devices that get an electric motor running at start-up or that help keep a motor running once it has started. I've been dragging my feet and have been living with an electric motor start issue for about three years. There are many variables to consider when purchasing or replacing electric motors. Therefore, if an extension cord is needed then the wire size should provide enough amperage for the motor of the equipment. Nice reading! You may hear it humming or observe that it's getting hot. The coupler is a means of connecting the rotary power of the electric motor to the transmission to power the car. By centrifugal starter, I assume you mean a switch that kicks in at low speed (located inside the motor ⦠Electric Motors in Muir on YP.com. Electric Motors in Charlotte on YP.com. I have replaced the bearings, one of them was seized up. Motors below 1 HP (0.7457) is directly connected to the power supply without starter because their armature resistance is very high and they have the ability to afford and pass higher current due to high resistance. If so, you will have to adjust the wire configuration of the motor leads for the appropriate voltage. The outlet is used frequently for table saw, grinder/planer,etc., the first time the motor started to hum was a couple of months ago. Check the nameplate on the motor to see if it can run on 110 and 220. If there is an electric motor shop in your area it would be great to take the motor or at least the capacitor in to be tested. Chances are the motor made a growling noise when you added power. My central A/C air handler stopped working. Dave. The size of capacitor needed for the job depends on the motor's energy starting ⦠The electrical circuit should be sized correctly to deliver the necessary starting amperage or inrush current. Testing the motor and capacitor should only be made after the electric motor circuit has been identified and turned OFF and Tagged. Sometimes using an extension cord is necessary, like when an air compressor is needed out at a job site. We are recently working on electric dryers and I am teaching them how to fix it. Browse photos and search by condition, price, and more. Craigslist has listings for electric motor for sale in the Flint, MI area. Check that the alignment between the motor pulley and the compressor pulley is straight and inline. Release the key when the motor starts. Thanks for your electrical question Charles. When I bought the saw I did see it run so I know the motor is good, but it was on 220. The switch could be stuck or contacts could bad. So basically you need a bigger power supply. I replaced the start capacitor with identical item and still have issues with start. Both capacitors are needed for the motor to start and run, so make sure they test OK, and all the other electrical components that were defective have been replaced. See reviews, photos, directions, phone numbers and more for the best Electric Motors in Charlotte, MI. Could be the centrifugal switch inside the motor. Hi Bryan, A motor starter is an electrical device that is used to start & stop a motor safely. After the motor reaches its operating speed, the switch disconnects the capacitor. Is this a capacitor issue? To safely stop a motor 3. A capacitor is used to supply this initial push to the motor. If you can turn the motor shaft by hand easily when the motor is not energized then it may in fact be the starting capacitor that is bad and needs replacing. It may be that this motor has a centrifugal switch that engages a start winding of the motor. It will start and run perfectly until you load the pump then it just hums and trips.Anybody with any help would be greatly appreciated. also try blowing the end bell out with compressed air. See reviews, photos, directions, phone numbers and more for the best Electric Motors in Muir, MI. Make sure the lubricating oil is at the full level. To reverse the direction of a motor 4. The only 1725 rpm motor i have is 3/4â shaft. When I plug it in all I get is a hum. My pool motor hums, but I can get it running if I turn the shaft by hand? Thanks, Doug, Hi Doug, If an existing motor is being replaced it would have been supplied with a manufacter's nameplate offering all the details about the original motor necessary for offering a replacement.
