Why do we need a ln298 in driving a stepper motor?

Why do we need a ln298 in driving a stepper motor?

The L298N operating voltage is between 4.8 and 46 volts (max 35 V when mounted on the breakout board). Since the driver can supply a maximum of 2 amperes per channel, you need to find a stepper motor that can be used in this voltage range and doesn’t exceed the maximum current rating.

How would you integrate the motor to the Arduino by means of relay?

Connect motor in between the middle terminal of relays. Out of two remaining terminals, one goes to the Vin pin of Arduino Uno and other to the collector terminal of transistor (for each relay). Connect emitter terminal of both transistor to GND pin of Arduino.

How do you do mechatronics?

Earn a relevant degree. Many mechatronics engineers start their careers by earning a bachelor’s degree in either mechanical or electrical engineering. Then, they gain knowledge of other engineering disciplines throughout their careers, moving serendipitously toward mechatronics along the way.

How does NEMA 17 work?

NEMA 17 is a hybrid stepping motor with a 1.8° step angle (200 steps/revolution). Each phase draws 1.2 A at 4 V, allowing for a holding torque of 3.2 kg-cm. NEMA 17 Stepper motor is generally used in Printers, CNC machines and Laser Cutters.

Why do we need a ULN2803 in driving a relay?

We need a ULN2803 for driving a relay because more current is generally required for driving a relay that is generally not provided by a micro controller, so we need a ULN2803 to increase the current limit.

How to control NEMA 17 with Arduino IDE?

First of all, add the stepper motor library to your Arduino IDE. You can download the stepper motor library from here. After that define the no of steps for the NEMA 17. As we calculated, the no. of steps per revolution for NEMA 17 is 200.

What kind of driver is used for NEMA 17?

The A4988 Nema 17 stepper driver is a microstepping driver module that is used to control bipolar stepper motors. This driver module has a built-in translator that means that we can control the stepper motor using very few pins from our controller.

How to control the direction of a NEMA 17 stepper motor?

Here a potentiometer will also be attached to control the direction of stepper motor. Operation of Nema17 is similar to normal Stepper Motors. NEMA 17 stepper motor has a 1.7 x 1.7-inch faceplate, and it usually has more torque than the smaller variants, such as NEMA 14.

How to define no.of steps per revolution for NEMA 17?

After that define the no of steps for the NEMA 17. As we calculated, the no. of steps per revolution for NEMA 17 is 200. After that, specify the pins to which driver module is connected and define the motor interface type as Type1 because the motor is connected through the driver module.
