REACTIVE SYNCHRONOUS ELECTRIC MOTOR Russian patent published in 1995 - IPC

FIELD: instrumentation engineering. SUBSTANCE: windings are put on two parallel rods with pole pieces. Stator is embraced with toothed rotor relative to which axis parallel cores with windings are positioned in symmetry. Angular extents of pole pieces of rods are equal to half of toothed division of rotor which teeth angular extent is equal to angular extent of space between them. Angular extents of spaces between edges of pole pieces of different cores are three quarters of tooth division of rotor on one side, are one quarter of tooth division of rotor on the other side and between edges of pole pieces of each of cores located on opposite ends of winding - integral number and a half of tooth division of rotor. EFFECT: improved precision of discrete movement. 5 dwg
