EB BAS 316g seems to be jammed/motor won't spin

[ejtrent]

Hey guys!

So sorry if this is the wrong section,

Basically I was cutting some pau rosa and for some reason it caught and then the machine just stopped and started making this grunting noise! The stop switch was non responsive but after 10 secs it tripped the RCD. After flipping it back on the stop button still refused to work. I've come in this morning and the stop button now works.. But still the same grunting... Video attavhed! Any ideas? Bit desperate as I need it for work!

It does spin freely!



Thanks so much

Could it be the capacitor?

OP seems confused in his use of terminology. An RCD would trip in milliseconds not 10 seconds!

I'd agree that the capacitor could have failed.

Take off the blade, wind a long string several turns of the driven wheel. Pull the string hard and as it comes off, switch on.
The motor should start. Switch off and wind the string the other way round. Repeat. The motor should start in the other direction.
This is a classic indication of failure of (in order of likely-hood)
1) capacitor - most probable solution - buy on ebay - not as a makers spare part which will be expensive.
2) centrifugal switch (inside the motor) - possibly repairable in skilled hands
3) start winding- motor right off in all but the largest of motors or ones with special mechanical features when rewinding will be needed.


The trip I suspect, was an MCB NOT an RCD

I'm not an electrics guy, all I know is after 10 seconds of being stalled/jammed it tripped my circuit..

Ok so I took off the blade and now it starts... But very slowly - as if the motor has little power?

It's like the motor has lost a lot of power

As said, new capacitor required.

 

[ejtrent]

That affects power?

That affects power?

The motor requires a little extra kick to get spinning from rest, the capacitor provides the kick. Hence myfordmans post above, if it powers up when manually 'started' its likely to be the capacitor.

Open up the terminal box on the motor to have a look at the capacitor(s). You might be able to see signs of melting or leaking fluids, note down the info on the capacitor specs. If you need one quickly maplin's sell them.

Hey all, replaced the capacitor and still getting the same problem of slow sluggish start then slow run speed, looks like it's new motor time? 95 quid in machine mart seems the best bet?

 

[ejtrent]

Oh and funny fact - when the earth isn't connected, the machine runs just like normal

 

[Myfordman]

Your motor has an internal insulation breakdown and should not be run unearthed under any circumstances.
A new motor is needed.

Yeah I don't have a death wish! I'm fitting a new motor today - thanks for all the help!

Would you mind posting what motor you are buying or a link to it on machine mart?
Thanks
