The STC1003 allows you to control a bipolar stepper motor (up to 4A). This Phidget connects to your computer through a VINT Hub.
Using motor controllers with large motors can pose a risk for your power supply. If your supply does not have protective features built-in, you can use a Power Guard Phidget to prevent damage from power spikes from back EMF that is generated when motors brake or change direction. We recommend that you use the SAF2000 for any motor with a coil current between 1.5 and 5 amperes, and the SAF1000 for motors above 5A.
The STC1003 can control both unipolar and bipolar motors, but in almost all cases you're better off with a bipolar motor due to their increased power and more precise step angles. If you care about torque, large motors with high gear ratios are your best bet. If you car about speed, motors with no gearbox and high step angles are better. If you want precision, steppers without gearboxes and low step angles are best because while gearboxes do result in smaller steps, they also introduce a flat 1-3 degrees of positional error due to backlash in the gears.

This Phidget requires a power supply between 8 and 30V DC. We recommend that you use a 12V DC power supply for small steppers and a 24V DC supply for larger ones. If you're not sure, check the data sheet for your motor for the recommended power supply voltage (not to be confused with the coil voltage, which is usually much lower). For best results, we recommend getting a 5 amp supply. Select the power supply from the list below that matches your region's wall socket type.
