MOTOR-TRANSDUCER SET Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: stator teeth 2-9 carry motor armature winding and output winding of combined position-and-speed transducer. Transducer field winding is placed in axial holes arranged along its axis. Pole number of rotor inductor and tooth number of armature equals, respectively, 2P = 18a and Z = 24b, where a = b = 1,2,3... Motor armature winding has N coil groups each incorporating two coils placed on adjacent teeth and assigned to same phase. Transducer output winding has four mentioned coil groups, two diametrically opposite groups per output phase. Even number of coil groups placed between adjacent groups of transducer output winding is chosen for motor armature winding and equals n = (3a - 1) + (i - 1), where i = 1,2,3... EFFECT: provision for mounting three electrical machines on common magnetic core as well as for electric isolation of field circuits and for taking information from position-and-speed transducer. 2 dwg
