1209 – Stepper Motor: Bipolar, 200 Steps/Rev, 35x36mm, 2.7V, 100

This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1000 mA at 2.7 V, allowing for a holding torque of 1400 g-cm (20 oz-in). The motor has four 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: 35 mm square x 36 mm, not including the shaft (NEMA 14) Weight: 180 g (6 oz) Shaft diameter: 5 mm Steps per revolution: 200 Current rating: 1000 mA per coil Voltage rating: 2.7 V Resistance: 2.7 Ohm per coil Holding torque: 1400 g-cm (20 oz-in) Inductance: 4.3 mH per coil Lead length: 12 in Datasheet Dimensions The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 36 mm. The output shaft has a length of 21 mm and a diameter of 5 mm.
