The Pololu Stepper Motor: Bipolar, 200 Steps/Rev, 57×76mm, 3.2V, 2.8 A/Phase is a robust NEMA 23-size hybrid bipolar stepping motor designed for applications requiring precise position control. It features a 1.8° step angle, translating to 200 steps per revolution, which ensures high accuracy in movement. Each phase of the motor draws 2.8 A at 3.2 V, providing a substantial holding torque of 19 kg-cm (270 oz-in), making it suitable for demanding tasks.
The motor is equipped with four color-coded wires terminated with bare leads, facilitating easy integration into various systems. It can be effectively controlled using a pair of H-bridges or a powerful bipolar stepper motor driver. The motor's versatility is further enhanced by its compatibility with multiple interfaces, including USB, TTL serial, I²C, RC, analog voltages, and quadrature encoder, when used with a suitable controller.
This stepper motor is ideal for a wide range of applications such as printers, CNC machines, 3D printers, laser cutters, pick and place machines, linear actuators, and hard drives. Its design allows for secure mounting using a NEMA 23 steel bracket, and it can accommodate additional components via a 1/4″ universal mounting hub or scooter wheel adapter. The motor's precision and reliability make it an excellent choice for projects where feedback control systems are not feasible.
