THYRATRON MOTOR WITH BUILT-IN TRANSDUCERS OF SPEED AND ANGULAR POSITION OF ROTOR Russian patent published in 2002 - IPC

FIELD: electrical engineering. SUBSTANCE: thyratron motor with built-in transducers of speed and angular position of rotor has stator with number of teeth Z_z = m•k•n, where m is number of phases of armature winding; k number of coil groups in phase; n is number of teeth in coil group. Each coil group comprises coils embracing one tooth of stator, connected in series opposition. Thyratron motor has rotor with permanent magnets alternating in polarity and magnetized radially. Number of permanent magnets is 2p = Z_z. Tachometric winding is dropped in slots of stator. Symmetry axis of each phase of tachometric winding coincides with symmetry axis of corresponding phase of armature winding. Coil groups of each phase of tachometric winding are interconnected as well as coil groups of armature winding. Each coil group of tachometric winding is made of even number of interconnected coils connected in series-opposition displaced relative one another by single tooth division of stator and are placed with pitch equal to odd number of tooth divisions of stator, from three to Z_z/к. Hall generators are used in the capacity of angular position transducers. Hall generator of each phase of armature winding is installed in slot of stator located on symmetry axis of coil group of corresponding phase with even number n of teeth in coil group or in slot of stator nearest to symmetry axis of coil group of corresponding phase of armature winding with odd number of teeth. EFFECT: simplified design and increased utilization factor of volume of thyratron motor. 2 cl, 1 dwg
