HELP !! Sanyo Denki stepper motors ??? what are these ones ??

I have a pair of Sanyo Denki stepper motors part number , type 103 845 2 , DC 3V , 6.7A , 1-8Deg/step , 6 wires

and

a pair of Sanyo Denki stepper motor type 103 807 5 , DC 5V , 1.9A , 1.8 Deg/step , 6 wires


Q1 . how many oz-in are these stepper motors ?

Q2 . from the part number how does one work out what these stepper motors are ?




i did search on the net for info , but it seems these stepper motors are old style of steppers. found this website www.sanyo-denki-online.com which did give some light on the topic but not enough to info to work out what my steppers are.

i'm am making a assumption from the website i have been on , since there 6 wires on these stepper motors there U=Uni-polar six wire


Any help would be appriciated

thanks guys

cheers



example from - www.sanyo-denki-online.com
Our simplified stock numbering system identifies each motor instantly. As an example, here is our Nema Size 34, 720 oz/in., 6 amp, single shaft, bi-polar motor. Here's how it works.

Example for stock # 346-720-SB
34 6 - 720 - S B B=Bi-polar four wire or U=Uni-polar six wire
. . . . . S=Single Shaft or D=Double Shaft
Ounce inches of holding torque rounded off.
The third digit(s) indicates the motor's amperage.
The first two digits indicate the Nema or Metric frame size.
