Choosing a Stepper Motor Power Supply

Some people may consider the stepper motor to be a bit more complex than a standard DC motor. This may be true to a degree, however stepper motors offer many more advantages compared to the DC motors. Some examples of these advantages include; easy control by computer, precise control of rotation, and high torque at low speeds.

When constructing a robot, or other system that uses stepper motors, you’ll need to have a DC power supply that can run the stepper motor. Stepper motors will run better when the voltages is several times higher than their rated voltage.

The first thing you will need to do when choosing a stepper motor power supply is to addStepper Motor Power Supply - Circuit Specialists up the voltage for your stepper motors. Determine the number of stepper motors in your system that have the same voltage requirements. Add their current ratings and this will help you determine which total current you will need. If you have four stepper motors and each needs ½ amp of current, your total needed current will be 2 amps.

Next you will need to examine the stepper motor specifications to determine the voltage rating. choose a power supply with a voltage at least double that voltage, and this will give you the voltage the power supply needs to run the stepper motors.

Now it is time to start browsing a power supply website to find a source for your stepper motors. The Circuit Specialists website offers a complete section dedicated to stepper motor power supplies. This makes browsing for the proper power source quick and easy. The final step in this process is to begin on your project.
