Outline of Final Research Achievements

In the positioning system that a rise and a descent move in the gravity direction, I take out a recovery current from a servo-motor ,and considered the micro moving mechanism which drives using a recovery current. Through experimenting I confirmed that a energy recovery occurs at the time of descent movement. the velocity and the load showed that the frequencies of the energy recovery.An enough the current can't be taken out yet unfortunately to drive the micro moving mechanism. I'd like to consider the way to take the recovery current out efficiently continuously.
