RELUCTANCE MOTOR Russian patent published in 1996 - IPC

FIELD: synchronous machine. SUBSTANCE: rotor core is built up of U-shaped laminated stacks whose radially oriented sections are arranged within active space of rotor and have varying height in axial direction that changes from zero on external radius to maximum value on internal radius of machine active zone obeying linear law; tangentially oriented section of stacks are of permanent height and are located in region confined by internal radius of machine active space. EFFECT: improved speed, power characteristics, mass and size, facilitated manufacture. 4 dwg
