Alternate motors.
Posted: Wed 19. Aug 2020 17:06
I have been testing motors for some time to see if we have resources available with similar properties as the Mag1 & 2 motor.
As they are tailormade without (to my knowledge) specification I have had to more or less guess and measure what the motors should be like.
The nearest I have got is the 2 listed.
But the main factor is the RPM at 3.7V given at some sources.
I have found motors with 20-22000RPM are well suited.
And as low as possible current drain.
Max 30-50 mAh at no load full speed are usable.
Stall current 1-1.5 Ah.
A year ago I found this one from Ebay- but have not been able to source it anymore :
FF-M20 DC 3V 3.7V 22000RPM High Speed Micro Mini M20 Motor 1mm Shaft RC DIY
size : 8x10x17mm 1mm shaft
The this summer I found this one. I got some, but of the 4 I got, 2 where used, one I could not spin by fingers. And the where all with very varying internal resistance. So for quality it is not a hit.
It runs, but noisy.
