If you're looking for a compact solution for controlling a medium-sized stepper motor, the STC1001 is an affordable and convenient option. You can control the position, velocity, and acceleration of the motor by sending commands from your program. This Phidget connects to a VINT Hub; for a list of options see the "Compatible Products" tab.

Safety Features

The STC1001 comes equipped with a heatsink to prevent the board from overheating during use. The power terminals on this device are polarity protected: if you happen to hook up the power supply backwards, the device simply won't power up and won't be damaged. A 5-amp automotive-style fuse is also included to protect the board from current spikes from the motor's back-EMF. This Phidget is isolated from input to output, so your VINT hub and computer will be protected if anything goes wrong.

Power Saving Options

For power-conscious users, we also allow for separate control over the current limit and the holding current limit. If you know your motor will be stationary for long periods of time, but still needs a small amount of holding torque to maintain its position, you can set the holding current appropriately without interfering with the running current limit.

  1. Connect the STC1001 to the VINT Hub using the Phidget cable.
  2. Connect the stepper motor to the Phidget's output terminals. See your motor's data sheet or product page for wiring instructions.
  3. Connect the VINT Hub to your computer with a USB cable.
  4. Connect the power supply to the power terminals on the STC1001.

Now that you have everything together, let's start using the STC1001!

Using the STC1001

Phidget Control Panel

In order to demonstrate the functionality of the STC1001, the Phidget Control Panel running on a Windows machine will be used.

The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:

Linux users can follow the getting started with Linux guide and continue reading here for more information about the STC1001.

First Look

After plugging the STC1001 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Stepper Motor

Double-click on the Stepper object, labelled Stepper Phidget, in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Toggle the Engage button to provide power to the motor coils.
  • By default, motor position, velocity, and acceleration are measured in sixteenths of a step. If you want to use different units, change the value in the Rescale Factor textbox.
  • Use the Target Position slider to set a new target position. Change the Acceleration and Velocity sliders to speed up or slow down the STC1001's approach.
  • Select the Velocity (Continuous) Control tab for continuous rotation instead of specifiying a position.
