Abstract

A vibration control assembly includes a housing having an interior region and an inner mass including a cage disposed within the interior region of the housing and being rotatable within the housing about a first axis and a gyroscope wheel disposed within the cage and rotatable about a second axis other than the first axis. At least one driving source includes a stator and is operable to interact with a magnetic field of the inner mass to drive rotation of the inner mass about at least one of the first axis and the second axis, wherein the at least one driving source is mounted within the interior region of the housing.

Claims (11)

1. A vibration control assembly comprising:

a housing having an interior region;

an inner mass including:

a cage disposed within the interior region of the housing, wherein the cage is rotatable within the housing about a first axis; and

a gyroscope wheel disposed within the cage and rotatable about a second axis other than the first axis; and

a first driving source comprising a stator operable to interact with a magnetic field of the inner mass to drive rotation of the inner mass about the first axis, wherein the first driving source is mounted within the interior region of the housing,

wherein the first driving source is operable to drive rotation of the gyroscope wheel about the second axis, wherein the first driving source is configured to control a rotational speed of the gyroscope wheel about the second axis and a rotational speed of the inner mass about the first axis, wherein the rotational speed of the gyroscope wheel does not depend on the rotational speed of the inner mass.

2. The vibration control assembly of claim 1 , wherein when supplied with a current, the first driving source generates a magnetic field that interacts with the magnetic field of the inner mass.

3. The vibration control assembly of claim 1 , wherein when supplied with a current, the first driving source is operable to induce a current in a portion of the inner mass.

4. The vibration control assembly of claim 3 , wherein the first driving source is an induction motor, and the portion of the inner mass includes a ferromagnetic material.

5. The vibration control assembly of claim 3 , wherein the first driving source is a brushless motor, and the inner mass includes one or more permanent magnets.
