Hi
I have an issue with my pump/motor for my swimming pool. I have checked the winding resistance and also to Earth, all good. The start capacitor is ok however I replaced it just to be sure and same issue. The issue is the pump/motor will start then struggle and eventually trip the thermal switch on top of the motor. I believe the start circuit should disconnect after it winds up and then the main windings take over. However when I opened the motor I did not notice any centrifugal disconnect switch. I have attached a simple diagram. Hopefully someone can understand it and help he out to whatbthe issue is. I have heard something clicking after the motor trips approx 10 seconds afterwards so it sounds like something is electrically connect/disconnecting. I also have to reset the thermal switch every time it trips obviously. I have attached photos of some of the components. Just to add the windings and armature looks good and clean and rotates freely.
Any thoughts with this would be gratefully appreciated
