基于CPLD的四相步进电机细分驱动器设计
Design of 4-phase micro stepping driver based on CPLD
摘要
Abstract
A 4-phase micro stepping driver based on CPLD was designed in the paper.We wrote the reference date of electric current in CPLD and designed chopper with VHDL.The driver can drive stepping motor to roll forward or backward with the DA converter and power amplifier.The maximum subdivision number of micro-step can reach 128,and the subdivision number is adjustable.The driver can realize accurate and real-time control over stepping motor and the cost is relatively low.关键词
