Phidgets 8A Stepper Phidget STC1002_0
The STC1002 allows you to control a bipolar stepper motor ( up to 8A). This Phidget connects to your computer through a VINT Hub and requires an 8-30V DC power supply.
Features:
- Control position, velocity, and acceleration
- Current Control - Set the current limit and holding current separately
- Two Drive Modes - Step mode specifies a target position in 1/16th steps. Run mode rotates continuously at a specified Velocity.
Technical Details:
- Isolation - The VINT hub and the computer will be protected if anything goes wrong with your circuit
- Polarity Protection - The device will not turn on and will not be damaged if the power supply is connected backward
- Overcurrent Protection - Onboard fuse to protect the controller in an over-current Event
- Failsafe Protection - Set the device to turn off if automatically your program becomes unresponsive
- Power Saving - Separate control over the current limit and the holding current limit
Warning
Make sure the power supply is unplugged before attaching or removing wires from the terminal blocks. Failure to do so could cause permanent damage to the Phidget.
Connection and Compatibility
Power Guards
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.

Bipolar Stepper Motors
The STC1002 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.

Power Supplies
This Phidget requires a power supply between 10 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.
