摘要
L297是一种适用于两相步进电机控制的专用芯片。利用L297芯片设计了一种两相步进电机驱动器,给出了该驱动器的驱动电路,并分析了其驱动特性。该驱动器可实现全步、半步控制驱动,具有大功率、斩波驱动、恒力矩、高可靠性等优点,可用于较大功率的机电设备中。
L297 is a type of dedicated chip applied in control of two phase stepping motor. A new design of two phase stepping motor driver based on L297 was introduced. The drive characteristic was analyzed and the driver circuit was given which can implement the full-step and the half-step control. The scheme has a novel thinking in the advantage of switch control, constant torque, high power and high reliability.
