I have just purchased these, for the princley sum of £10 + p&p. They should be arriving tomorrow, so I was wondering how I can safely test them? The guy says the resistance of the coils is good, but that means nothing to me. Also, I was wondering if anyone knew anything about these motors/manufacturers as i have no info on the motors apart from:
Evershed and Vignoles Ltd
London W4
Split Field Servo Motor
Type FB6A/A1/B
Serial No 1335473

Field windings are 1.74 k ohm
rotor is 11.5 ohm
Wt of each motor 4Kg
I have no servo drives, so testing with them is out, and unfortunately the company no longer exists! All help appreciated!
