I wonder if some one can help me to find information about this motor.
data sheet/specification

Model: E660
Part no: 0660-37-059
Costom part no: 5D65951H01 rev:J

Is there nobody out there that have info?

Reliance Electric DC Servo motor Model E660
NEMA 34 Frame
Back EMF Constant, ke = 65 V/kRPM
Torque Constant, kt = 5.5 lb-In/Amp
Nominal Speed Rating: 1750 RPM
Nominal Voltage Rating: 120 Volts

Encoder;
HEDS-5605 A06 500 cpr

-05 winding option,
11.42 Ohms winding resistance, and an 8.1 A Max peak
current. 5.5 In/Lb / amp x 8.1 A = 44 In-Lb or 717 In-Oz.

Thank you. what I see is that the encoder appears to be from Avago Technologies, on my motor, manufactured by Renco.
p/n 77676-312

You should be able to get the encoder info from the Renco site.

Can this really be correct? 11ohm winding resistance on a size34 motor sounds like A LOT. You'll drop 92.5V across the winding when pushing 8.1A thru it, with a 120V supply there won't be much left to actually turn the motor.

Any data on the continous current rating?

I'm not saying the data is incorrect it just doesn't "feel" right....

I have 5 winding variations listed in my ancient Electro-Craft book. They range from 0.44 Ohms to 11.42 Ohms. These motors (at least when made by Electro-Craft) had a dash number following the main part #. So, it would be something like E-660-01

Winding #   -01             -02             -03              -04              -05
Kt           13.2            27.6            44.2             66.1            88.5  Oz-In/Amp
Kv           9.76            20.4           32.7               49             65.5  V/1000 RPM
R            0.44            1.28          3.00               7.1             11.42 Ohms
Imax         54.2            26            15.8              10.7            8.1     Amps

Imax is peak current, not max continuous current.

Thanks Jon,
It's probably correct then. Don't know if I would like to use it though.....

I know Imax is peak and not continous, that's why asked if there was any data listed for continous current ;-)

I have the information for the 0660-07-074, I am not sure how close the specs will be to yours.

Thank you for your interest. the problem was in the encorder. A new one is ordered. The specification does not work on my motor
