5 Phase Stepper Motor Driver Projects
With a 5-phase motor, there are 10 steps per repeat in the stepping. Looks like a stepper motors drivers dream chip for the do it yourself.
Hi, Welcome to the forum. Please read the first post in any forum entitled how to use this forum. Then look down to item #7 about how to post your code. It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png? Including you power supplies, please no Fritzy picture. Can you post a picture of your project too please?
What driver do you have? Links to data/specs of driver and stepper. I know its a lot but we need this information to give you accurate answers Thanks Tom. Hi, Thanks for the diagram, you will not be able to power those steppers off the 5V of the MEGA. They will need their own 5V power supply. Your stepper driver has provision for that as well. Go back and start with just ONE stepper and get it working, you can get one of those geared steppers to work off the arduino power and USB.
Do not be surprised if you have to swap the 4 driver outputs around to get the stepper to rotate back and forth. PS I have those components as well, I'll assemble the project with one stepper when I can. Mains Power means your utility AC supply, what is the supply you are using, PC or USB adapter.
Basically there are two types of stepper motors: bipolar and unipolar. The bipolar stepper motor is a two-phase brushless motor which has two coils (windings), this motor has 4 wires (2 wires for each coil).

The other type is the unipolar stepper motor, it is 4-phase brushless motor which has 5 or 6 wires. The popular controlling modes of of the stepper motor are: full step and half step. The full step can be divided into 2 types: one-phase and two-phase. In full step one-phase mode the driver energizes one coil at a time. This type of controlling requires the least amount of power but provides the least torque. In full step two-phase mode the driver energizes the two coils at the same time.
This mode provides the highest torque but it requires twice as much power as one-phase mode. Half step mode is a combination of the two full step modes (one-phase and two-phase). This mode increases accuracy by dividing each step by 2.
It requires power in-between one-phase and two-phase modes, torque also is in-between. There is another controlling type called microstepping, this type is more accurate than the half step mode, it requires two sinusoidal current sources with 90° shift. In this example I’m going to use the full step two-phase mode for controlling the bipolar stepper motor. The following image shows a simple schematic of the bipolar stepper motor: To be able to control the bipolar stepper motor, two H-bridge circuits are required. In this example I’m going to use quadruple half-H driver which can work as dual H-bridge driver.
This chip is small, low cost and easy to use, these make it a good choice for students and hobbyists, in this blog, I used it in some DC motor control projects. In the full step control mode always both windings are energized at the same time according to the following two tables where first table shows the driving sequence for one rotation direction and second table for the other direction: Related Projects: Hardware Required: • Arduino UNO board • Bipolar stepper motor • L293D motor driver chip —-> • 10k ohm potentiometer • Pushbutton • Power source with voltage equal to motor nominal voltage • Bread board • Jumper wires Arduino bipolar stepper motor control circuit: Example circuit diagram is shown below. All grounded terminals are connected together. The L293D chip has 16 pins with 4 inputs (IN1, IN2, IN3 and IN4) and 4 outputs (OUT1, OUT2, OUT3 and OUT4). The 4 outputs are connected to the bipolar stepper motor as shown in the circuit diagram.
