I bought motors, power supply components and geckos, not as a kit, but supposedly "matched", if you will, for compatability.
I am wondering if my DC voltage is too high for the motors... they seem pretty hot to the touch.
There are no markings on the motors but the documentation that came with them shows the following:
Holding torque:640 oz/in
Rated current/phase(amps dc): 5.5
Phase resistance:0.42 ohms
Induction(mH) 3.5
The rest is from my own calculations...which could very well be wayyyy off:
5.5 amps X 0.42 ohms=2.3volts...(rated voltage???)
2.3v x 25(the maximum factor over rated voltage)=57.75v
My power supply is putting out 68vdc.
Is that too high?
Recently one of my geckos went south. I was considering switching to one of the 4 axis systems available from several vendors.
Thanks for you consideration.
