Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 57x41mm, 5.7V, 1 A/PhasePololu
Ab Warenkorbwert 50€ ein Aufkleber gratis!
This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 5.7 V, allowing for a holding torque of 3.9 kg-cm (54 oz-in). The motor has six color-coded wires terminated with bare leads that allow it to be controlled by both unipolar and 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 it as a bipolar stepper motor.

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:
- CNC machines
- 3D printer/prototyping machines
- Laser cutters
- Pick and place machines
- Linear actuators
- Hard drives
