This paper presents an optical fiber positioning unit for LAMOST. The data port of the parallel port constitutes the intelligent controller of the stepper motor. The system uses an audio power amplifier as the bridge mode driver circuit of the stepper motor. The main method to improve the positioning precision of the unit is studied. The system sets mechanical zero using electronic switch as the reference zero of the revolving unit to reduce the accumulative error of multi positioning. The system uses a spring mechanism to eliminate gear clearance and improve its stability. Experiments show that, with a precision of 40 μm the positioning unit can position the fiber quickly and precisely.
