Additionally,itincludestwoPWM choppercircuits toregulatethe current in the motor windings.With a suitable power actuator the L297 drives twophase bipolar permanent magnet motors, four phaseunipolarpermanentmagnet motorsandfour phasevariable reluctance motors. ![]() This note describesthe operation of the circuit and shows how it is used.The L297 Stepper Motor Controller is primarily intendedforuse with anL298Nor L293Ebridge driverin stepper motor driving applications.It receives control signals from the system’s controller,usually a microcomputer chip, and provides allthe necessarydrive signals for the power stage. Unipolar stepper motor can be driven with an L297 plus a quad darlington array. Usedwith a dual bridge driver such as the L298N forms a complete microprocessor-to-bipolar stepper motorinterface. ![]() APPLICATION NOTETHE L297 STEPPER MOTOR CONTROLLERThe L297 integratesall the control circuitry required to control bipolar and unipolar stepper motors.
