Abstract:
1. A magnetic suspension system for supporting a shaft in a housing, the system comprising: a first array of magnet members disposed proximate a first end of the shaft between the shaft and the housing, the first array of magnet members comprising a first magnet member, a second magnet member, and a third magnet member, wherein the first magnet member and the second magnet member generate a first force that is substantially parallel to a longitudinal axis of the shaft and the second magnet member and the third magnet member generate a second force that is substantially parallel with the longitudinal axis of the shaft and wherein the first force and the second force are configured to position the shaft axially within the housing; and a second array of magnet members disposed proximate a second end of the shaft between the shaft and the housing, the second array of magnet members comprising a fourth magnet member, a fifth magnet member, and a sixth magnet member, wherein the fourth magnet member and the fifth magnet member generate a third force that is substantially parallel to the longitudinal axis of the shaft and the fifth magnet member and the sixth magnet member generate a fourth force that is substantially parallel with the longitudinal axis of the shaft.
