註釋

A design for a motor-speed controller of low cost and high precision, is presented. It makes possible the regulation of the rotation speed of a series-wound electric motor to an accuracy of +/- 1.5 rpm over the range 15 to 5000 rpm. The design incorporates a digital display of the rotation speed, and provides for the programming of the speed by an external voltage source.
