Stepper Motor Nema 17 4500g-cm

Stepper motors a type of DC motors that move in increments or steps, they move at a known interval for each pulse of power. These pulses of power are provided by a motor driver and is referred to as a step. As each step moves a known distance it makes them handy devices for repeatable positioning. Stepper motors are usually used on CNC Machines such as 3D Printers, Laser Cutters, CNC Routers.

To utilize the full power of a stepper motor you will need a dedicated stepper motor driver such as DRV8825.

Applications

These 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 they are often found:

• Printers
• CNC machines
• 3D printer/prototyping machines (e.g. RepRap)
• Laser cutters
• Pick and place machines
• Linear actuators
• Hard drives
