1 to Fig. Outline showing how double force pulse is produced by a single switched D.C. pulse. Graph showing oscilloscope trace of characteristic voltage across stator windings. Important Factors Care must be exercised when assembling and wiring the drive windings to make sure that their polarities match the rotor magnet polarity. Robert Adams' machines were built varying from 0.03125 to 27 ohms per set, He has experimented with two, four, and eight pole machines.
Efficiency increases with the number of wound poles in the stator.
Motor generators with a single, two, or three phase can be built to this design. A number of rotors may be ganged together on the same shaft in order to increase power output and does not require the use of any commutator, brushes or slip rings, all of which contribute to energy losses in ordinary motor generators. Unlike conventional Series D.C, machines, this motor can be off-loaded, finds its own speed, and will run at that speed indefinitely. A conventional DC motor will run itself to destruction with off-loading. It requires no cooling, nor any overload protection, even if short circuited.
