Abstract:
A rotator system comprising:a universal electric motor comprising:a motor shaft;a commutator attached to the motor shaft;an armature having an armature diameter, an armature thickness, an armature aspect ratio, and armature windings, the armature aspect ratio equal to the armature diameter divided by the armature thickness, the armature windings being electrically coupled to the commutator, the armature aspect ratio being no less than three, a portion of the armature having a magnetic permeability such that when the armature portion is saturated by a magnetic field, the armature portion is saturated at or above 1.8 Tesla, the armature being attached to the motor shaft; anda stator having a stator outer diameter, a stator thickness, a stator aspect ratio, and stator windings, the stator aspect ratio equal to the stator outer diameter divided by the stator thickness, the stator aspect ratio being no less than five, a portion of the stator having a magnetic permeability such that when the stator portion is saturated by a magnetic field, the stator portion is saturated at or above 1.8 Tesla; anda rotatable device coupled to an end portion of the motor shaft.
