These are the most common type of AC motor and are important to industry due to their load capacity, with Single-Phase induction motors being used mainly for smaller loads, for example in household appliances whereas, Three-Phase induction motors are used more in industrial applications including compressors, pumps, conveyor systems and lifting gear.However, with a higher power, the overall maintenance costs increase and would need to be taken into consideration.The DC Motors speed can be controlled by varying the supply voltage, they are available in a wide range of voltages, the most popular types are 12 24V.Applications include automotive, hoists, lifts and cranes as it has a high starting torque.
It has a medium level of starting torque with constant speed, so its suitable for applications including lathes, vacuum cleaners, conveyors grinders. This type has a high starting torque and can run smoothly if the load varies slightly, its used for driving compressors, variable-head centrifugal pumps, rotary presses, circular saws, shearing machines, elevators and continuous conveyors. ![]() The advantages of this technology is a long life, little maintenance and high efficiency (85-90), whereas the disadvantages are higher initial costs and more complicated controllers. ![]() This is an informative tutorial to teach you the basics of any stepper motor control, I already posted a video about controlling speed and direction of DC motors and today we will get started with the stepper motors and hopefully in the next tutorial I will explain how to play a bit with some servomotors. You can watch this video if you dont want to read the whole post: During the making of this post, we tried to make sure that this tutorial will be the best guide for you in order to enjoy learning the basics of stepper motors controlling since this is so important especially for those who want to start electronics and robotics learning. What you will learn from this tutorial: Define the stepper motors Uses and Needs. Start testing and debugging Step 1: What Are the stepper Motors. A typical driving pattern for a two coils bipolar stepper would be: A B A B We can define the coils patterns using a millimeter by measuring the resistance between the stepper connection wires, and it should measure some resistance between each two coils ends, please check the photos above. Electrical Motor Controller Projects Driver And EveryIn order to make the stepper moves, a sequence of power polarity should be sent from a controller through the stepper driver and every time the sequence change the stepper perform a step in a precise direction with a constant speed which is the sequences speed so the faster the sequences move the faster the stepper rotate. In our tutorial we will use the A4988 driver which allows us to easily control direction and speed of the stepper and could provide up to 35V 2Amps output control for the motor, the driver will be connected to an Arduino Nano board which is the heart of our control part. JOIN ME ON JLCPCB COMMUNITY HUB Invitation link: Backing to our circuit diagram as it shows the photo above we have the Arduino board connected to the stepper motor through the A4988 driver. About the driver we will need three pins to connect to Arduino which are the Enable, the step and the direction pins. About the driver output you will connect each pin the appropriate coil end. One important thing is connecting the sleep and reset pins to each other, otherwise the motor will be trembling and wont move. Do not get confused on steps and full rotation because a step on our motor is a 1.6 degree angle and a full rotation is 360 degrees angle so our stepper will almost spin for 5 rotations in each direction. After preparing the circuit as it shows the above photo all what it need now is uploading the code, then we plugin the external power supply for the stepper and it should be applied on Vmot input pin. Do not forget to connect the reset pin and the sleep pin to each other. Following this tutorial you are now able to control and test your stepper motors coming from electronic devices like 3D printers. Let me know through the comment section what other tutorials do you want me to make for you, do not forget to thumb this tutorial if you like it and to follow us for more awesome projects. One last thing, make sure that you are doing electronics every day.
