Yes, there's no way i'll need to run the saw for 15mins un-interupted under normal usage. The motor got hotter than it's been before, but I could keep my hand on it without getting burnt. Is it because it's a 60hz motor? Is there absolutely nothing I can do about that? jon.

One thing I forgot to add though, the motor was really hot, almost too hot to touch, and this is something that I hope won't cause me any future problems. Q. How hot can an induction motor get before it fails? jon.

Hello Bob, I have just read Brians messages and yes, it's a contractor saw by the sound of it with a 115v motor, so he has to run it on a transformer. We do however have some good news (fingers crossed) I,ve spoken to an engineer today at work and he needs me to take the motor out so he can...

Thanks Paul. So when you had yours, What was the longest time you had your saw running for. (roughly). jon.

Thanks for that Bob. I'm going to try it on about 15amps then if still cutting out in the same time span, i'll take the motor to Beatson fans and motors.(local motor rewinders+engineers) More on this tommorrow. cheers, jon.

I do appreciate all the members taking the time to follow this thread. jon.

Hello, does anyone over here have a Delta unisaw? If so please, please, please tell me if it's a 60hz motor and have you had any trouble with the overload cutting out the saw after 5mins or so of running? Also, can you tell me what the tiny amperage dial inside the starter is set on. Thanks to...

Good idea about raising it 1amp at a time to see if the time to trip gets longer. The motor plate on the extractor doesn't have rated amp on it. I've already had a look to compare but that motor is a 1.5kw output (two horse) whereas the saw is a three horse, so I would have thought that if the...

Herdsman, How is it then, that on the saw plate, it say's the motor is rated at 12.4 amps. Or is this NOT the full load amperage? jon.

If the worst comes to the worst, i'll get a new motor for it but are we basically saying that anyone who has an induction motor run machine from the US will have experienced the same? jon.

Fair comment Bob, I have an extractor that only has a two horse motor and in that starter, the dial is set at 17 amps, that was set by Axminster and has never tripped in two years. Are you fairly certain I could raise the dial in the saw's starter then? jon.

What adverse effect can setting the amperage dial in the starter have on the motor then? jon.

Bob, I have tried it when the starter is set on 12 just over. It say's inside the starter cover, do not exeed the FL amperage of the motor or motor burnout could occur. I dont want to risk that. jon.

The blade is driven by a three belt pulley configuration. I'm absolutely certain that the overload is cutting in due to overheating, now why it's overheating is something else! jon.

I got a missed call on my mobile today and when I called back it said sorry, you've dialled an incorrect number!!. So how the hell did they call me in the first place then? jon.

I would do Bob If it stopped cutting out after 10 mins use. (still no joy) Going to speak to a motor engineer tommorrow. jon.

Hello, I have had another close look and listen to the motor when running and there is definitely the distinctive click sound from the motor when you press the stop button and the motor starts to slow down, does anyone know if this is the sound of the centrifugal switch turning off? cheers, jon.

Hello again, First of all, the manual say's the motor is made to run on 220-240v which should mean it's ok with our electrics, now the hz on the motor is 60 and ours over here is 50. I have just looked inside the nvr starter and the overload amp dial is actually set at just under 12 amps and...

On a final note Bob, the motor runs very smoothly with no buzzing at all and the motor is rated at 12.4 amps with the NVR tiny dial set at bang on 12!!, should it be a little higher? jon.

I think we can definitly say that it's overheating first of all. Now, there's nothing obstructing the motor fan and air can flow around the motor, so can we say that it has to be the starter winding not cutting out? jon.
