Stepper Motor: Bipolar, 200 Steps/Rev, 57×56mm, 2.5V, 2.8 A/Phase:

This high-torque hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2.8 A at 2.5 V, allowing for a holding torque of 13 kg-cm (180 oz-in). The motor has four color-coded wires terminated with bare leads: 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.

1/4″ universal mounting hub and 1/4″ scooter wheel adapter can be used to mount objects on the stepper motor’s 1/4″-diameter output shaft, and we carry a NEMA 23 steel bracket for securely mounting this stepper motor to a flat surface (the picture above shows this bracket being used with a taller NEMA 23 stepper motor).

Specifications:

• Size: 56.4 mm square × 56 mm, not including the shaft (NEMA 23)
• Weight: 0.7 kg (25 oz)
• Shaft diameter: 6.35 mm (0.25″) “D”
• Steps per revolution: 200
• Current rating: 2.8 A per coil
• Voltage rating: 2.5 V
• Resistance: 0.9 Ω per coil
• Holding torque: 13 kg-cm (180 oz-in)
• Inductance: 2.5 mH per coil
• Lead length: 30 cm (12″)
• Output shaft supported by two ball bearings

Dimensions:

The following diagram shows the stepper motor dimensions in mm. The output D-shaft has a 0.25″ (6.35 mm) diameter with a section that is flattened by 0.5 mm (note: the diagram below incorrectly lists this flattened width as 6 mm when it is really 5.85 mm). This shaft works with 1/4″ universal mounting hub and 1/4″ scooter wheel adapter.

Stepper Motor: Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase:

This small NEMA 8-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). With a weight of 60 g, this is one of the smallest stepper motors we carry.

This small hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. These leads connect to the stepper motor through a removable JST-ZHR-5 connector. The motor can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver or one of our Tic Stepper Motor Controllers. In particular, the Tics make control easy because they support six different interfaces (USB, TTL serial, I²C, RC, analog voltages, and quadrature encoder) and are configurable over USB with our free configuration utility.Our 4 mm universal mounting hub can be used to mount objects on the stepper motor’s 4 mm-diameter output shaft

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 (e.g. RepRap)
• Laser cutters
• Pick and place machines
• Linear actuators
• Hard drives
