Unite MY1018, MY1016, MY6812 -- what specs do they meet?

[david82282]

I noticed the MY1016, MY1018, and MY6812 motors have a variety of specs published on the web. The most detailed at http://www.cn-dcmotors.com/product11.asp shows impressive numbers. But other sites have considerably worse specs, especially for the no-load current, which has a big effect on efficiency.

Have any of you measured the no-load current and no-load speed on these motors (at full voltage)? If so, could you post that data with the motor model? Also helpful would be the armature resistance (though at about an ohm, that can be difficult to measure accurately).

I'm putting together some Excel spreadsheets that analyze these motors at different voltages, and as generators, and can post these if that's of interest.

Thanks, David

It's unclear to me if Unite's specs / graphs concerning their motors are even real.
