Bipolar Stepper Motor Control

First, we want to explain how such a controller works and what’s involved. A bipolar motor has two windings, and thus four leads. Each winding can carry a positive current, a negative current or no current. This is indicated in Table 1 by a ‘+’, a ‘–‘ or a blank. A binary counter (IC1) receives […]

The Using of L297 in Stepper Motor Driving Applications

Here we provide you with an application note article contain information about the L297 Stepper Motor Controller which is typically intended for using with L298N or L293E bridge driver in stepper motor driving applications. You will be described with the operation of the L297 integration control circuitry and also figure out how it is used. […]
