My planer /jointer has just developed a problem.
When I start the machine up the head starts to turn then stalls and starts a growling noise (for want of a better word) ,the motor overheats and cuts out.
I have taken the drive belt off and the motor works fine, I checked the head and it seems fine, bearings turn freely and no play. When I reinstall the drive belt stalls again. i.e motor do not seem to work under load, Any ideas Keith

Hi Keith, Have you got the feed engaged for thicknesser/planer, when this happens?. Colin ? Sent from for Windows 10 ?

Keith,
Not sure what is happening but few pieces of info may help. Single phase or 3 phase? Is electric brake working, load or no load?

If I disengage the infeed the motor works sometimes, but other times just makes a growling noise
It is single phase 230v

Hi Imran
? ? ? It is 230v single phase, I do not know how to tell if the electric brake is working.
If I disengage the infeed drive , the motor will work just sometimes, but if I remove the drive belt from the pulley the motor works every time

Keith,
The cutterhead would spin for a long while if the brake is not working. With brake it stops in ~8 sec give or take a few seconds. There is also a hum when brake is working. If properly calibrated the hum should stop same time as cutterhead comes to a stop or fairly quickly afterwards but not before. There is nothing wrong if the hum continues for short time afterwards as long as machine is not restarted.
I have not thought about brake function with no load but imagine it would stop quickly not having to fight the moment of a heavy spinning cutterhead. I cannot imagine a reason for it to not work in this scenario.
There has been a report of brake board failure that resulted in overheating of motor but in your case the motor runs fine in no load condition. Have you run it for a longer duration with no load? I imagine if it is brake board causing the overheating, it might take longer to shutdown under no load.
Sorry, that is all I can think off. Hopefully, someone else can offer better guidance. In case of overheating, I personally would check the current motor is pulling to rule out the motor.

That would be interesting as it appears to start okay. I guess run cap could be bad but I am not aware of noise associated with it. My exposure is limited to reported problems here on FOG so maybe learning something new.

I know others have bought replacements of Amazon. You need to look at the writing on the casing and get the appropriate one.. a search through the posts here might come up with the values. My machines are three phase so I don’t have the caps. Any local motor rewinding shop or electronics supply house should be able to supply replacements also.

Keith,
Glad that was easy to figure out. Was the racket more like a loud hum?
Either way if the machine is old go ahead and replace both caps. You can look for them at following. I recently got in’s from Mouser for my bandsaw.

Keith,
In that case be careful running after cap install. Never heard of any racket with bad caps. The motor (and cutterhead) could oscillate but usually that is not a racket. Do you have chain for feed rollers? I can see that making noise if motor was oscillating. I assume you don’t have a separate motor for feed rollers and it is one of those with urethane covered wheel. Good luck.

I suspect he has lost one or both of his capacitors. Did you hold the start button in until the motors reach full speed?
Keith,
The cutterhead would spin for a long while if the brake is not working. With brake it stops in ~8 sec give or take a few seconds. There is also a hum when brake is working. If properly calibrated the hum should stop same time as cutterhead
comes to a stop or fairly quickly afterwards but not before. There is nothing wrong if the hum continues for short time afterwards as long as machine is not restarted.
I have not thought about brake function with no load but imagine it would stop quickly not having to fight the moment of a heavy spinning cutterhead. I cannot imagine a reason for it to not work in this scenario.
There has been a report of brake board failure that resulted in overheating of motor but in your case the motor runs fine in no load condition. Have you run it for a longer duration with no load? I imagine if it is brake board causing
the overheating, it might take longer to shutdown under no load.
Sorry, that is all I can think off. Hopefully, someone else can offer better guidance. In case of overheating, I personally would check the current motor is pulling to rule out the motor.

Hi Imran
? ? ? It is 230v single phase, I do not know how to tell if the electric brake is working.
If I disengage the infeed drive , the motor will work just sometimes, but if I remove the drive belt from the pulley the motor works every time
Keith
Keith,
Not sure what is happening but few pieces of info may help. Single phase or 3 phase? Is electric brake working, load or no load?
Imran
?My planer /jointer has just developed a problem.
When I start the machine up the head starts to turn then stalls and starts a growling noise (for want of a better word) ,the motor overheats and cuts out.
I have taken the drive belt off and the motor works fine, I checked the head and it seems fine, bearings turn freely and no play. When I reinstall the drive belt stalls again. i.e motor do not seem to work under load, Any ideas Keith

Keith,
That can explain the noise. Hopefully, all will be well with new caps. Sorry for dragging on, but almost 30 yrs of design work inherently included root cause analysis. I miss work sometimes and this is therapeutic.

Keith,
In that case be careful running after cap install. Never heard of any racket with bad caps. The motor (and cutterhead) could oscillate but usually that is not a racket. Do you have chain for feed rollers? I can see that making noise if motor
was oscillating. I assume you don’t have a separate motor for feed rollers and it is one of those with urethane covered wheel. Good luck.

Thanks?Imran, yes the racket was definitely loader than a hum.
Keith?
Keith,
Glad that was easy to figure out. Was the racket more like a loud hum?
Either way if the machine is old go ahead and replace both caps. You can look for them at following. I recently got in’s from Mouser for my bandsaw.

I know others have bought replacements of Amazon. You need to look at the writing on the casing and get the appropriate one.. a search through the posts here might come up with the values. My machines are three phase
so I don’t have the caps. Any local motor rewinding shop or electronics supply house should be able to supply replacements also.
Hi Brian
?I suspect you are right ,I started up the motor and let it get to full speed. then engaged the infeed , this ( I assume it's a capacitor) started smoking then popped out of the casing . If it is a capacitor any idea where I can pick one up ,I live in Canada

Keith,
Thanks for the update. Great news. As we hypothesized the racket likely came from chain drive for the feed rollers.
Happy woodworking.
