Lab 9. Stepper Motor Controller Overview of this Session In this laboratory, you will learn: To continue to use an oscilloscope How to use a Stepper Motor chip Introduction This lab is focused around the control of a stepper motor. You will be using the SAA1042 Step Motor Driver chip to implement the various stepping sequences. Background In lecture you learned how a step motor works and how you can manipulate the phases to make the rotor move. The phases of the step motor must be energized in a specific order for this to work. Luckily the SAA1042 chip knows how to sequence the phase properly. All you have to do is tell it which direction and which stepping sequence you want (full or half). IMPORTANT: Take a look at the pin out. There are five places where ground must be attached. Since the step motor uses a lot of current, the chip needs to have the ability to sink that current. Make sure you hook up all five GND pins to ground . Before applying power, check the circuit twice. Incorrect power connections will destroy the chip and perhaps melt the breadboard.
