Multi-Axis Precision Subdivision Driving System Design for Polarization Maintaining Fiber Automatic Fixed Axis
摘要
Abstract
The automatic fixed axis technology of the PMF involved precise positioning, testing and adjustment of optical fibers’ position and posture, putting forward higher requirements for the precise adjustment of optical fiber position and orientation in real time. Designed and implemented multi-axis stepper motor subdivision driver control circuit used to the automatic fixed axis of PMF. The circuit took TI’s DSP2812 as the control system core architecture, using DRV8846 as a power stage driver chips, designing the scheme of current decay mode and automatic segmentation based on the study of stepper motor control and segmentation drive the principle. It effectively inhibited the noise and mechanical vibration in the movement of the motor, improving low-frequency vibration, high-frequency step-out, and to enhance the sports performance of the stepper motor.关键词
