Systems Design, Fabrication, and Testing of a High-Speed Miniature Motor for Cryogenic Cooler
Figure 16
Linear stability map for 1st and 2nd bending modes shown as a function of speed: (a) Bearing damping = 1 N-sec/mm, and (b) Bearing damping = 0.01 N-sec/mm. Positive log decrements indicate a stable system.
