Lars Dernebo: Method for making a motor quieter. LD DESIGN ELECTRONICS, Fasth Law Offices, Rolf Fasth, January 30, 2018: US09882515

The method is for making an electric motor more efficient by iteratively changing when a processor sends activation signals to transistors to minimize a current required to rotate a rotor at a constant rotational speed. The method is also for changing a rotational direction of the rotor by switching ...
