LionelHuz, Just want to mention that it is not my hobby. I am an Electronic engineer, tend to change my field. I got involved in electric motors and if you had time to read all the tests that I have done you will find that it is for fun. from the beginning, all I found was strange for me as I...

First, I really appreciate for all comments and even dArsonval comments even the way it was explained. Well, As I tried to well understand most proposed ideas, I tried to add some loads on the motor and see the results. The air gap between the router and magnets are rally small and less than 1...

Thanks a lot for your feedback. Well I would say that I am agree with you. while I could not find any issue (visible parts) inside the motor, but I am agree with you. I also checked the air gap and it sounds good to me. I will upload a photo here to show it (may be be helpful for someone else)...

Thanks Waross. First I should say, based on the schematic that I attached (which I found by tracking the connectors and connection inside the Motor), I found that the black wire goes to the centrifugal switch. this means it is for start coil. Also, another piece of existing black wire goes to...

Hello everybody, first, I would like to thank everybody for taking time and helping me to solve my issue. Here is another brief of what I have done last weekend:I disassembled the Motor again, check all the mechanical issues. 1- I used multimeter beep test and ohm test to check the wires for...

yes, there is only one start Cap on this motor which is 400-480 MFD - 110 VAC. I measured the current passing trough it and after running it drops to 0 A (0.06 exactly)

Thanks Zlatkodo for your explanation. Would you please let me know what is the reason for such a reaction from Motor. it does not make scene. on theory, the motor is designed for a specific RPM with some limits. what defines the limits are the coil wiring and some other factors. increasing the...

as I live in Canada, the residential power voltage is 120 V. I will check it today but I would say it is is 120 V.

I already checked the coil and it seams that they are really separated. I did beep test and tested with a power supply. it is a general purpose motor and based on the pulley that I founded on it, it should be used as a blower fan. there was a kind of V-belt pulley already installed on the...

I did some more investigation. Now I can confirm that the Red coil (Red-Black wire) is the start coil and the yellow coil, yellow-Blue wire is the running coil. I assembled the motor and measure the Cap current when the motor was running and it gave 0.065 A. still the No load current is around 7...

Hi thanks for your replies. Actually, it is a CGE electric motor. internal condition sound good to me and based on what I have found on theories, it sounds good except the No-Load current and generated heat. I didn't expected too much current without Load, even higher than its rated full Load...

Thanks for your reply. I am an electronic engineer and trying to change my filed. that's why I sent my post here to ask from professionals. how can I check if that is the fault of start coil. is it possible to disconnect the starting Capacitor and make it run by turning the shaft and then...

Hi  I have a single phase electric motor. I got it from a friend that did not use it for a while. I cleaned it up and it sounds that all components are ok. I removed all dusts and add some oils to the bearings.  bearings are ok. I cleaned the connectors and checked them all and all sounds good. ...
