MOTOR-WHEEL Russian patent published in 1995 - IPC

FIELD: transportation means. SUBSTANCE: motor-wheel has armature 2 with magnetic circuit 3 and groups of electromagnets 4.1 and 4.2 put on axle 1. Armature carries ring contact 5, main 6.1 and supplementary 6.2 distribution contacts corresponding to groups 4.1 and 4.2 and composed of current conducting insulated plates with each other one interconnected in groups. Field structure 7 has magnetic circuit with permanent magnets 10 arranged evenly with alternating polarities and current collectors having electric contact with collector distribution plates 6.1 and 6.2 and current collector 15 having electric contact with contact 5. Current collectors in this case perform commutation of low voltage across controlling inputs of commutators commutating high voltage across coils of electromagnets of stator. Due to this voltage across electromagnets of rotor can be raised as heavy current flows directly through coils but not through brushes. This leads to increase of forces of electromagnetic interaction and to enhanced reliability of motor thanks to sudden drop of current through brush-and-collector unit. EFFECT: enhanced reliability of motor-wheel. 3 cl, 3 dwg
