Patent ID: 8387235

Claim:
An apparatus comprising: a table having a support area that is configured to support and mount a machine and an electric motor having a stationary stator and a rotating rotor that is coupled to a shaft of the machine; a tool configured to engage and remove the rotor from the motor when the machine is mounted to the table, and the tool is configured to be operatively connected to the table to move back and forth on the table relative to the machine and the motor; wherein the tool comprises a housing and a piston, wherein the housing is configured to be detachably coupled to the rotor, and wherein the piston is configured for engagement with an end of the shaft, and wherein the piston has an end concentrically aligned with the rotor and the shaft when the piston is positioned for engagement with an end of the shaft; a driving mechanism configured to be linked to the piston and that is configured to actuate and move the piston in a backward or forward direction relative to the machine and the motor; a first adapter configured to be mounted to the end of the piston for engaging the end of the shaft when the piston moves forward toward the machine and the motor to remove the rotor from the motor; and a second adapter detachably coupled to the first adapter and configured for engaging the end of the shaft when the piston moves backward relative to the machine and the motor to install the rotor in the motor; wherein the housing of the tool is configured to move on the table in a direction that is opposite to a direction of movement of the piston to remove or install the rotor responsive to the movement of the piston.
