| Abstract: | This article introduces a control-driver used for quarter-phase stepper motor. The driver consists of the L297 stepper motor control chip and the power-driven circuit. L297 chip generates pulse phase sequence signals of which the pulse width is adjustable. The signals are the input ones of dual bridge driving circuit and drive the stepper motor after amplification. In this article, the design principle of L297 chip and dual bridge driving circuit is stated. The driver is used for NC machine tool successfully. |
