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.
More specifications are available in the datasheet (352k pdf).
