What type of driver circuit is required for driving a stepper motor?
What type of driver circuit is required for driving a stepper motor?
The Driver circuit for a Unipolar Stepper Motor can be constructed with the help of few transistors or a Darlington Transistor IC like ULN2003. But, the driver circuit for a Bipolar Stepper Motor requires an H – bridge type connection. Hence, we use H – bridge ICs like L293D to drive Bipolar Stepper Motors.
How much voltage is L293D?
The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
What is a L293D motor driver?
The L293D is a popular 16-Pin Motor Driver IC. As the name suggests it is mainly used to drive motors. A single L293D IC is capable of running two DC motors at the same time; also the direction of these two motors can be controlled independently.
How do I control a stepper motor using the l293d motor driver?
Controlling a stepper motor using the L293D Motor Driver. A stepper motor can be connected to the L293D motor driver by using the two H-Bridge circuits in the driver where each of these H-bridges controls one of the electromagnetic coils of the stepper motor. The diagram below shows how the stepper motor is connected to the H-Bridges.
What are the pins on the l293d Motor Driver module for?
The L293D motor driver module has two H-Bridge circuits and therefore can control two dc motors simultaneously. The pins IN1, IN2, IN3 and IN4 are actually for controlling the switches of the H-bridge circuit of the L293D module.
What is the l293d IC?
The L293D is capable of providing bidirectional drive currents up to 600mA at voltages from 4.5V to 36V. This IC can drive inductive loads such as motors, Relays, Solenoids, and bipolar stepper motors. This IC L293D comes in 16 pin PDIP package. It has Internal ESD protection, High noise immunity inputs and wide supply voltage range 4.5V to 36V.
How to control a stepper motor with Arduino?
One of the easiest and inexpensive way to control stepper motors is to interface L293D Motor Driver IC with Arduino. It can control both speed and spinning direction of any Unipolar stepper motor like 28BYJ-48 or Bipolar stepper motor like NEMA 17.
