Abstract
A d.c. motor that operates by electromagnetic impulsions rather than through continuous electrical energization and which is characterized by permanent rotor magnets reactively associated to permanent stator magnets that produce rotary action on the permanent rotor magnets by being made of progressively increasing or decreasing width circumferentially around the rotor and of appropriate polarity to either produce a net magnetic attraction or repulsion on the permanent rotor magnets.
Claims12
A d.c. impulsion motor comprising a stator including permanent magnet means having one polarity spread over at least one distinct polarity portion progressively varying in effective cross-sectional size in one circumferential direction around the stator a rotor including permanent magnet means having one permanent rotor magnet extending over a predetermined angular portion thereof, in adjacent and reactive path relationship relative to said one distinct polarity portion of said permanent magnet means, a uniform air gap being provided between the permanent magnet means of said stator and rotor, respectively, electromagnet means secured to the stator in circumferential continuity with said permanent magnet means and positioned in adjacent and reactive relationship relative to said one permanent rotor magnet, a d.c. power supply, and a d.c. power distributor connected to the d.c. powersupply and to the electromagnet means and constructed and arranged for synchronized energization of the latter upon passage of said one permanent rotor magnet in angular registry with said electromagnet means.
