This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). It offers a holding torque of 1 kg-cm (14 oz-in), and each phase draws 1 A at 4.5 V. This stepper motor’s flat profile (16 mm including the shaft) allows it to be used in places where more traditional stepper motors would be too bulky.
