Pololu Stepper Motor Bipolar, 200 Steps/Rev, 2.8V, 1.7 A/Phase

This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm. The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other.
