Abstract

In the present state of the motor art, motor shafts are pressed into the rotor or attached by an adhesive in such a manner that the shaft is permanently attached to the rotor. If the same basic motor is employed in multiple applications requiring different shaft lengths, then generally three different motors must be inventoried. The final assembly of the component to the motor shaft usually may not be completed until after the motor is mounted in the machine because the component either blocks the motor mounting screws or it will not fit through the available opening. An advantage may be obtained in a motor if the shaft is removable rom the rotor so that the stator (with the rotor in place) may be easily installed in its application early in the final machine assembly procedure.
