Pulsating current electromotor without commutator

Claim 1

A pulsating current brushless electric motor comprising: a rotor fixed to a rotating shaft, said rotor comprising magnetic poles diametrically opposed to one another relative to the shaft and extending over the greater part of the circumference of said shaft, the poles having an opposite polarity with respect to one another; a stator formed by a substantially cylindrical hollow body within which the rotor is arranged, the stator comprising stator slots uniformly spaced about the inner circumference of said stator, distinct stator multiple layer windings contained within said slots, each distinct stator winding following the internal perimeter of said stator slots so as substantially to cover the internal surface of the stator, and which, at the outlet from each slot, are traversed by current always in the same direction; detector means comprising an opaque member fixed to said shaft, said member having an arcuate extent equal to 360° divided by said number of windings, said member cooperating with photodiodes, one photodiode being associated with each of said multiple layer windings, such that said opaque member alternately interrupts and restores a beam of light transmitted by each of said photodiode, said photodiode further being uniformly distributed about the circumference of the shaft; electronic means controlling power distribution to the stator windings, said electronic means being responsive to the angular displacement of the rotor as communicated by the interruption of the photodiode beam corresponding to its associated stator winding; and a power source from which the motor components receive their power.
