ABSTRACT:
The rotor structure of a synchronous inductor motor, such as a stepping motor, is of a compact, simplified and high-efficiency construction consisting essentially of wholly planar annular laminations which include stacks of thin externally-toothed elements bonded together and with relatively thin axially-magnetized annular washer material extending radially from a relatively large central shaft fully to the roots of the stack teeth.
