The Pololu Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 57×56mm, 3.6V, 2 A/Phase is a versatile NEMA 23-size hybrid stepping motor suitable for both unipolar and bipolar configurations. It features a precise 1.8° step angle, translating to 200 steps per revolution, which ensures accurate positioning and smooth operation. The motor is designed to draw 2 A per phase at a voltage of 3.6 V, providing a robust holding torque of 9 kg-cm.

This motor is equipped with six color-coded wires with bare leads, facilitating easy integration with various stepper motor drivers. In unipolar mode, all six leads are utilized, while in bipolar mode, the center-tap wires can be left disconnected, allowing for flexible control options. The motor’s construction includes a 56.4 mm square frame and a 56 mm length, with a shaft diameter of 6.35 mm, supported by two ball bearings for enhanced durability and performance.

For optimal performance, it is recommended to operate this motor in bipolar mode using a high-power stepper motor driver. This configuration maximizes the motor’s capabilities, ensuring efficient and reliable operation in demanding applications.
