This homemade stepper motor controller can control the speed and. Fully integrated stepper motor driver or the ucn5804b or the mc3479. Both the first and second driver board use the same motor power supply, so the positive and negative wires for each individual driver board go to the same spot.
Stepper motors need a driver in order to work, however there is a simple trick to make them run directly from a transformer. The controller we are going to built is based around a4988 stepper motor driver. The m860h stepper motor driver is first a foremost a powerful driver that is able to drive most large stepper motors. Its a relatively cheap and can easily be found on any online electronics store. How to run a stepper motor without a driver youtube. For more interesting projects consider subscribing. Drive keeps current in the motor below the fixed value which keeps motor burning out. These have two coils and are controlled by changing the direction of the current flow through the coils in the proper sequence.
The driver needs a pwm input on the step pin to operate the motor. The reprapped development board rdb series of pages in particular, rdb stp and rdbstp001g diy has some ideas about making motor drivers that are optimized for diy, for flexibility and for upgradeability. Building a better bipolar stepper motor driver general discussions. Where it says arduino pin in the circuit, i use pins 2,3,4,5 for the first stepper motor altitude and pins 6,7,8,9 for the second stepper motor azimuth. The integrated motor driver i used is no longer made, but it is similar to l6208powerspin. St has released a new evaluation board for a stepper motor driver.

A pulse generator could be used to complete such a task and cuteminds has put together a diy friendly version tailored specifically for stepper motors. This is a full featured controller which only needs 2 variables as input. A chopper drive can run the stepper motor with much higher voltage than the motor s rated voltage. How to make a stepper motor controller without using a micro. My a4988 board gets very hot, very quickly, to the point that im afraid that it might burn out. Now before we get into more details have a look at the data sheet of the stepper driver. Higher voltage allows the current to flow through the stepper motor faster, which gives the ability to turn it faster with more torque. Remember those dc motors, all you need too do is to hook up the positive and negative leads to a battery and holla it starts. The trick with a stepper motor is that you need to drive the four poles of the motor to a.
