Stepper Motor: Bipolar, 200 Steps/Rev, 35×26mm, 7.4V, 0.28 A/Pha

Description

This hybrid bipolar stepper motor has a step angle of 1.8° (200 steps/revolution). Each phase draws 280 mA at 7.4 V, allowing a holding torque of 650 g-cm (9 OZ-in). The motor has four colored wires terminated with bare conductors: black and green connect to one coil, red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver. Specifications Size: 35 mm square × 26 mm, not including the shaft (NEMA 14) Weight: 130 g (4.5 oz) Shaft diameter: 5 mm Steps per revolution: 200 Current rating: 280 mA per coil Voltage rating: 7.4 V Resistance: 26 Ohm per coil Holding torque: 650 g-cm (9 oz-in) Inductance: 19.2 mH per coil Lead length: 12 in Dimensions The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 26 mm. The output shaft has a length of 21 mm and a diameter of 5 mm. Though not shown in the diagram, the output is a D-shaft with a section that is flattened by 0.5 mm. Stepper Motor Applications Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted. Here are a few applications where stepper motors are often found: Printers CNC machines 3D printer/prototyping machines Laser cutters Pick and place machines Linear actuators Hard drives Bipolar stepper motors; from left to right: 20×30, 28×32, 28×45, 35×26, 35×28, 35×36mm.
