electro-craft motors

[KPyro]

This seems to be the place to ask about old electro-craft motors.

Can anyone (AL) tell me the specs on these motors

Motor 1
model 670/596
part# 8-100003-2

Motor 2 (looks the same as motor 1)
model E670/596
part# 7-7470-1
customer#5810043

Motor 3
Model E540
part# 7-7470-2

Mainly how much Voltage and Current can I hit them with safely.
and any other good info.

Thanks
Ken

I couldn't find those, Some of the E type were DC brushless, or are these DC, there are some numbers that are close, Often Reliance/Electro-Craft used OEM numbers for special orders.

These are DC brushed motors.
They have a tach.
the first two are ~3" x 6.75"
the last one is ~2" x 4"

Thanks

Are they C face or Sq flange? what is the length from motor brush to flange?

there round not square mount.
There 5.9" from the center of the brush cap to the front of the motor.
I will attach a few pics.
The mounting holes are about 45mm apart.
the output shaft is ~.308" dia and ~2.25" long

Thanks

I don't have anything on those series, I believe they pre-date all the info I have.

Thanks for the info and trying.
I'll just do the trial and error method with em.
Thinking they may just become spindles.
