2 months of trouble, but started working tonight. So i removed the motor, powered the hall board with a bench power supply and tested the output of them, all of them worked ok. I measued ressitance...

Thinking about what next, maybe going off the rails ? (but that's how I like to think about stuff :abnormal:)
Looking at the parts list, does it have to be a motor of that type ? I know it would be...

A hi-fi/TV repair place wouldn't know where to start. This is a specialist job - you need to know how brushless controllers work to start with. I suspect the manufacturer wouldn't bother fault...

I didn't realise that you have stalled the motor while cutting. As Irvine says you have probably taken out the output stage. Try replacing all of them as he says and see what happens. But you could...

It's true what Irving is saying but in the interests of keeping things cheap and easy try this first.
I'm guessing you mean the RCD is tripping, in that case you may have put something to ground...

Sorry to have to say this, but your lack of understanding of electronics means you are clutching at straws. Almost certainly one or more of your output MOSFETs is faulty. Simple resistance...

Any luck with this yet ?

The L7824 is a 24volt voltage regulator. Resistance measurements across it's legs tells you nothing about it's condition.

They're pretty indestructible, having built-in thermal shutdown, output...

Using the Fluke meter is okay.



Yes



ideally, can you see a number on this component ?

Happy New Year !

See the circuit board mounted on the end of the motor, make sure it goes back in exatly the same position. You can see it has slots to allow rotation.
If you are using a 500v...

I was busy looking at the pictures when irving replied. The box is as he says a mains filter. If this was faulty it would cause the fuse in the supply plug to blow and not the ones on the control...

The metallic box in the last pic with the chinese writing is an EMI filter to stop interference & noise from the VFD getting back on the mains supply.

Agree with Web Goblin,
3. A small amount of oil would not be of much concern, but obviously better without it, it's the oil seal that is suspect. It may also be that it's the gearbox at fault, maybe...

Looks like the motor is inverter driven.
1- Some inverters will shut down depending on what type of fault they see on the motor windings and some don't, they just blow up.
2- As above
3- Any oil...

Hi, wellcome to the forum. Am I the only person who does not know what a BF 46 is (maybe I am BF!!). Good luck. G.

Vince, Welcome, unless you have sight problems you may want to reduce your font size a little.
