Techical specification Electrocraft 0643-08-013 ?

[wotje]

Hello,

Is there anybody who can give me techhnical information about a DC motor from Electrocraft.
I did purchase them on a fleamarket.
I did a search on the internet but there is not much information avalable.
I do have 2 motors., model no. L19-2 and one E19-2.
The difference is how the shaft is made. Farther are they both the same.
Part number : 0643-08-013.
And both motors do have a electrical brake on it.
The length of the motors without shaft and the brake is 140 mm or 5 and a half inch.
And the with is 83 mm or 3 and a qurter inch.
If somebody could tell me the maximal voltage and the nominal current. I would already be happy.
If there is somebody who nows the rest of the specifications. Then it is in words impossible to tell you how I feel me. ;<)

Thanks

I have the catalogue specs on 0643-31-011 & 0643-32-011 models, these were the 0643 off-the-shelf models and I believe the other numbers are special order and may have been just different mounts or shaft size etc.

max terminal voltage 60
max speed 4800 rpm
inertia .0304 oz-in-sec^
Kt 16.8 oz-in/amp
Ke 12.4 v/krpm
max pulse current 43 amp
Inductance .5mH

0643-32-004
continuous stall 9.7 lb-in
