In this post , we 'll see how to control a spindle motor using the Microcontroller PIC 16F84A.
The spindle motor is a special type of Brushless DC ( BLDC )Motor that runs on high speed.
Unlike other types of motors, spindle motors have more than 2 terminals ( They can have 3 , 4 or five terminals ) .
Of course, the output current of the Microcontroller is not sufficient to drive the motor coils. There is an interfacing IC that can supply the motor coils with the suitable driving current.
This IC is ULN2003. It acts as an electronic switch opened and closed according to the output signals of the Microcontroller.
I connected the ULN2003 IC to the Microcontroller on the prototyping bradboard.
You can find the source code and simulation files on this link.
You can get this offer of 5 stepper motors with 5 ULN2003 boards from Amazon
