(28 mm) NEMA 11 PKP Series 2-Phase Bipolar Stepper Motors > Item # PKP225D15B2. STEPPER MOTOR. Also, if you want a constant speed, you might dispense with accelstepper (it's about accelerations after all), and just use the basic Arduino Stepper library. Sometimes the unipolar stepper motor is referred to as a "four-phase motor", even though it only has two phases. Stepper Motor. Some motors can be odd, and move in different amounts for each step. 8°, and accurate control is provided by pulse signals. The Arduino Motor Shield is based on the L298 (), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors.
