4.1. Choosing the power supply, Tic, and stepper motor
The information in this section can help you select a power supply [https://www.pololu.com/category/
84/regulators-and-power-supplies], a Tic controller, and a stepper motor [https://www.pololu.com/category/87/
stepper-motors] that will work well together.
Stepper motor configurations
There are different types of stepper motors. The Tic is designed to work with two-phase stepper motors
that can be connected in a bipolar configuration. The following diagram shows examples of such
stepper motors:
The Tic works with two-phase stepper motors that can be controlled in a bipolar
configuration.
Your stepper motor should have one of the configurations shown above, or else it might not work with
the Tic. The next section [https://www.pololu.com/docs/0J71/4.2] explains how to connect these stepper
motors to your Tic.
Voltage and current ratings
When selecting your power supply, Tic controller, and stepper motor, you must consider the voltage
and current ratings of each.
The voltage range of your power supply is the range of voltages you expect your power supply to
produce while operating. There is usually some variation in the output voltage so you should treat it as
a range instead of just a single number. In particular, keep in mind that a fully-charged battery might
have a voltage that is significantly higher than its nominal voltage.
The current limit of a power supply is how much current the power supply can provide. Note that the
power supply will not force this amount of current through your system; the properties of the system
and the voltage of the power supply determine how much current will flow, but there is a limit to how
much current the power supply can provide.
