Dc Regulator

Hi All,

Just purchased a Maxon A-max motor.

Its model 110182 6V 7 Watts.
The speed constant is 1380 rpm/V That means very slite changes in V will effect speed greatly.

Any recomendation for a voltege regulation with very fine V tuning. (I would like to use Battery)

I know very littel in electronics, could buying a lab DC regulator on ebay offer a good solution ?

Thanks
Izhak
