Abstract
An apparatus for mechanically coupling a motor to a rotor includes an outer ring including an inner surface shaped to define multiple recesses, an inner ring disposed within the outer ring and shaped to define multiple compartments having respective outer openings, which face the outer ring, and respective inner openings opposite the outer openings, and multiple gripping elements disposed within the compartments, respectively. The inner ring is configured to receive the rotor while the compartments are aligned with the of recesses, by virtue of the gripping elements sitting at least partially within the recesses. The outer ring is configured to couple with a shaft coupled with the motor such that rotation of the shaft by the motor causes the compartments to become misaligned with the recesses, thereby causing the outer ring to push the gripping elements, through the outer openings, against the rotor, through the inner openings.
