Applications and test machines
Akira Chiba
In this chapter some examples of bearingless drives that have been developed by various manufacturers are presented. The characteristics, requirements and development purposes are described. The applications for these drives are:
1. Canned pumps and drives;
2. Compact pumps;
3. Bubble bed reactor;
4. Blood pumps;
5. Spindle drives; and
6. Semiconductor processing.
