Keling DC Motor test results   Message List  
Reply | Forward Message #9088 of 19813 |
Hi,

I uploaded the test results for a Keling Technology NEMA-34 DC motor
called "KL34_150_90.pdf" to the files section, "G320 and G340 Stuff"
folder.

This turns out to be an unexpectedly good servomotor when a G320 is
modified to counteract the effects of this motor's pronounced cogging.
See the report's scope pictures for details.

Otherwise, the motor delivers 440 Watts mechanical (0.59 HP) at 4,865
RPM with a G320 and a 72VDC power supply. The motor's price makes it a
real value at this power level.

It's 47 times I / (7 - I) not 47 minus I / (7 - I). That gives 282K; use 270K as the closest standard resistor value. Mariss ... Geckodrive.com...

Mariss, your test report on the motor was very intriguing. I am wondering whether the proposed "K" version of the driver would be appropriate for use with...
