Control Stepper Motor with L293D Motor Driver IC & Arduino As L293D IC has two H Bridges, each H Bridge will drive one of the electromagnetic coils of a stepper motor. By energizing these electromagnetic coils in a specific sequence, the shaft of a stepper can be moved forward or backward precisely in small steps. Bipolar Stepper Motor | Electrical4U A bipolar stepper motor has easy wiring arrangement but its operation is little complex. In order to drive a bipolar stepper, we need a driver IC with an internal H bridge circuit. This is because, in order to reverse the polarity of stator poles, the current needs to be reversed. This can only be done through a H bridge. Bipolar Stepper Motor: 5 Steps Instructables Bipolar Stepper Motor: I had some stepper motors from broken HP printers ,hard drive and other electronic devices ,So I thought that it would be a good idea to make them work. in the beginning I started with uni polar stepper motor (5,6 wires) with ATMEGA8 MCU and ULN... Stepper motor driving STMicroelectronics The advantage of the bipolar circuit is that there is only one winding, with a good bulk factor (low winding resistance). The main disadvantage is the more complex drive circuit needing the two changeover switches for each phase. This is implemented as a full H bridge for each phase and requires more transistors that the unipolar configuration. Using L298N Stepper Motor Driver To control 4 wires stepper motor In this video you will learn how to control a 4 wire stepper motor with L298N Stepper Motor Driver module. ...
