Abstract

A high torque, high-acceleration stepper motor, having balanced design, is provided with identical cylindrical permanent magnets PM which are positioned about the shaft S and are secured to the end covers C to provide the necessary magnetic flux for rotor R, which is a hollow iron cylinder connected to the shaft. The inertia of the rotor is thus kept to a minimum, as also are any axial forces on the rotor.
