Abstract: The electromagnetic hanging and releasing machine is a subsystem of the micro-gravity falling tower. The key techniques, the electromagnetic releasing processes, and the micro-gravity experiment using the falling tower are discussed in this paper. Gimbal suspension device and electromagnetic releasing adjusting technology are used, so that the releasing process can be adjusted and controlled to reduce the interference and guarantee the micro-gravity level of the falling module. The experiment results show that the falling module is released smoothly and steadily and the falling state does not deviate from its vertical direction, and the falling module is recovered successfully.
