Checking stepper motors.

<< < (2/3) > >>

waggle:
I am not able to turn the shafts, not sure if this means they are seized or if they should be like this. I know they were working when they were removed from their old home.
The wires are :

1st motor: 2 blacks and earth
2nd motor: brown/blue/earth

The markings are;

escap   34
L 11 219 E 5

also

(EX) sd l G3
PTB nr lll
B/E -27  909
24VDC

Hope this means something to someone.

I will sort out some pictures for later

Cheers
Tony

Neither seem to be steppers, just maybe DC motors .. ???

AFAIK the minimum number of wires to a stepper is 4, ie bipolar connected.

'escap' ??

Portescap ??

Their stuff is very good and very expensive IIRC .. not your usual junk.

Cannot find anything in the search box with the numbers you gave.

Both motors should turn by hand, unless there is a reduction gearbox attached  to them, in which case you may have problems in the gearbox, or more likely, a high reduction ratio. If, in fact, you are turning a g/box output shaft, you may be trying to spin the motor itself at a high rate of knots.

They don't by any chance vaguely resemble this motor ?? ie an ally blob on the end ??

Ok, I will try and sort out a 24 volt supply and give them a go.

They are definately Escap as I have found something similar on Ebay.

In their original role they were very slow turning ( maybe 10-20 rpm ) so the shaft problem may well be down to gearing.

Thanks

Does not have to be 24V.

12V Car Battery will ekkle the things, or should do  :thumbup:

Thanks Bluechip.

I'll give it a go.
