MOTOR-GENERATOR WITH MAGNETIC CONCENTRATORS Russian patent published in 2019 - IPC H02K23/04 H02K1/17 H02K1/24 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used as motor-wheels in vehicles. Pulse motor comprises a stator with two ring-shaped magnetic conductors with permanent magnets with alternating polarity and magnetically conductive plates (concentrators), and external rotor with electromagnets connected via current collectors with distributing collector. Each magnetic conductor has the same even number of permanent magnets of each polarity and concentrators, wherein two pairs of permanent magnets of different polarity are separated by one concentrator so that the same-end permanent magnets are attached to the concentrator on both sides. Electromagnets are transverse horseshoe-shaped, located opposite each other and have two coils with serially opposite direction of winding. Distributing header comprises identical even number of alternating positive, negative and return segments. Number of segments of each type is equal to the number of concentrators.

EFFECT: improved weight and size characteristics, increased efficiency, increased maximum torque at low currents.
