Get moving with this powerful Bipolar Stepper Phidget. With a maximum power supply of 30V, it can provide up to 4A of current to each stepper coil. The result is that you can control the position, velocity and acceleration of one large bipolar stepper using a port on your VINT Hub (See the Comaptible Products tab for a list of hubs). Steppers are especially popular in applications where accurate positioning is important.

Safety and Protection

The Stepper Phidget comes with a number of safety features, since motors have a reputation of damaging unprotected circuits with current spikes when a motor stalls or changes direction under heavy load. There's a fuse socket with a 5A automotive fuse to protect your Phidget in just such an occasion, and the power terminals are polarity protected in case the power supply gets wired up backwards. The VINT port on this Phidget is isolated from the power circuit, so you don't have to worry about damaging your hub or computer if something goes wrong. Ensure that this Phidget is in a well-ventilated area if you plan on running it close to maximum specifications.

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.


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.

Getting Started

Welcome to the STC1000 user guide! In order to get started, make sure you have the following hardware on hand:

Next, you will need to connect the pieces:

STC1000 Functional.jpeg
  1. Connect the STC1000 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.

Now that you have everything together, let's start using the STC1000!

Using the STC1000

Phidget Control Panel

In order to demonstrate the functionality of the STC1000, 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 STC1000.

First Look

After plugging the STC1000 into your computer and opening the Phidget Control Panel, you will see something like this:

STC1000 Panel.jpg

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:

STC1000 Stepper Example.jpg

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 STC1000's approach.
  • Select the Velocity (Continuous) Control tab for continuous rotation instead of specifiying a position.

Technical Details

Rescale Factor

Power Consumption

The quiescent (idle) power consumption of the STC1000 varies depending on the amount of voltage it's supplied.

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 STC1000 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.

Phidget Cables

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

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.
