Patent ID: 6891292

Claim:
A series of motors, especially for attachment on drives, for alternating current motors having various pole configurations and operable in differing performance classes, voltage classes, and frequency classes, the series of motors comprising: a plurality of trunk motors, each trunk motor including: a motor housing optionally having ribs formed thereon for cooling assistance; stator windings mounted in a rotationally symmetrical manner in the motor housing; a rotor having a trunk motor shaft; a motor terminal box having a terminal board for the connection thereto of a current supply for the provision of electrical current to the stator windings; a pair of bearing brackets for supporting the shaft of the rotor such that the rotor is disposed within the stator windings at a minimal clearance therefrom sufficient to permit rotation of the rotor relative to the stator windings; a drive side; a non-drive side; and a shaft end of the trunk motor shaft extending outwardly from the non-drive side, the shaft end being adapted for securement thereto of a plurality of differing attachment shafts, the series of motors being configured such that each trunk motor is operable in cooperation with a plurality of differing attachment pieces and accessory pieces connected to the plurality of various attachment shafts.
