Abstract: A centrifugal compressor is provided. The centrifugal compressor includes a plurality of diffuser vanes arranged in a circumferentially spaced array about a machine axis. Each diffuser vane is mounted on a respective shaft. Each of the shafts is coupled to a ring that is rotatable about the machine axis. A worm drive is provided that includes a worm that meshes with a worm gear or a segment of a worm gear mounted along a portion of the circumference of the ring. A step motor is coupled to the worm. The step motor is operable to rotate the worm about a worm axis perpendicular to the machine axis, such that the worm drive transmits rotational torque from the step motor to the ring, to resultantly vary the position of the diffuser vanes.
