(3) How to balance the rotation
Find out the rotation speed at which the vibration reaches the maximum, within the actual rotation speed range of
the spindle motor. Run the motor at the speed found above and perform balancing to minimize the vibration. When
balancing is decided, measure the vibration at different rotation speeds and make a further fine adjustment so that
the vibration acceleration generated is always 0.5G (4.9m/s
2
) or less.
(The vibration acceleration of 0.5G is about 4.7
μ
m when expressed in terms of the amplitude at the rotation speed
of 10,000r/min. The higher the rotation speed is, the smaller the corresponding amplitude becomes.)
