FYP 2 || WEEK :: 7 Test Control Stepper Motor Using Labview

A common stepper motor is the four-coil unipolar. They are called unipolar because they require only that their coils be driven on and off. The stepping sequence for a four-coil unipolar steppers is shown on table 4 below.

Stepping sequence for a four‐coil unipolar steppers

 

The motor’s speed depends on how fast the controller runs through the step sequence. The stepper motor I have used is the 17PM-J319-02OST from Minebea-Matsushita. It requires a supply voltage of 12V and the coil current is 0.31A. Each step is 1.8 degrees.

FYP 2 || WEEK :: 6 Construct Stepper Motor Driver Circuit

The motor’s speed depends on how fast the controller runs through the step sequence. The stepper motor I have used is the 17PM-J319-02OST from Minebea-Matsushita. It requires a supply voltage of 12V and the coil current is 0.31A. Each step is 1.8 degrees.The USB Daq-6008  digital output current drive is about 20mA – too low to drive the stepper motor coil. Besides, the 17PM-J319-02OST stepper motor operates from a 12V supply which is higher than the 5V allowed for the USB Daq-6008 digital output. Therefore, one simple solution is to add the ULN2803. Figure 22 shows the pin configuration of ULN2803. It is a high voltage, high current darlington driver comprising seven NPN darlington pairs. All feature integral clamp diodes for switching inductive loads. The ULN2803 has a maximum sustaining output voltage of 50V and maximum output current of 0.5A per channel which easily exceeds the requirements of the 17PM-J319-02OST stepper motor. Figure below also show the circuit diagram and the PCB motor driver that is use for the Solar Tracker.
