1200 – Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 42x48mm,

This hybrid stepping motor can be used as a unipolar or bipolar stepper motor and has a 1.8° step angle (200 steps/revolution). Each phase draws 1200 mA at 4 V, allowing for a holding torque of 3.17 kg-cm (44 oz-in). The motor has six color-coded wires terminated with bare leads. Our 5mm universal mounting hub (see related products) can be used to mount objects on the stepper motor’s 5mm-diameter output shaft. Specifications Size: 42.3 mm square x 48 mm, not including the shaft (NEMA 17) Weight: 350 g (13 oz) Shaft diameter: 5 mm Steps per revolution: 200 Current rating: 1200 mA per coil Voltage rating: 4 V Resistance: 3.3 Ohm per coil Holding torque: 3.17 kg-cm (44 oz-in) Inductance: 2.8 mH per coil Lead length: 12 in Connections This stepper motor can be controlled by unipolar or bipolar stepper motor drivers. When used with a unipolar stepper motor driver, all six leads are used. When used with a bipolar stepper motor driver, the center-tap yellow and white wires can be left disconnected (the red-blue pair gives access to one coil and the black-green pair gives access to the other coil). We recommend using this as a bipolar stepper motor if you have a bipolar driver. Dimensions The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 48 mm. The output shaft has a length of 24 mm and a diameter of 5 mm.
