Re: Felder AD 531
¿ªÔÆÌåÓýKeith, 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. Imran? On Mar 14, 2021, at 12:31 PM, keith turner <keithturner01@...> wrote:

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,
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?

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 |
