The previous module on LAMOST (Large Area Multi-Object Fiber Spectroscope Telescope) controls and drives only
one fiber positioning unit, resulting in a low integration. Meanwhile, each unit is driven by two motors respectively
located on the center revolving shaft and the eccentric revolving shaft. In this case, these positioning units require a mass
of power connecting wires that increase flexible connections in excess and decrease the system linearity. To make an
improvement, this paper proposes a new module, which occupies small space in compact structure and is able to drive 37
optical fiber positioning units simultaneously. The module design of the controlling part and the driving part are based
on FPGA with its strong capabilities of parallel processing, large quantities of I/O resources and low power
consumption. With experiments, the new designed module improves the level of system integration, ensures the
reliability and reduces the power consumption, which meets all the requirements as expected.
