![]() Internally to control the stepper motor we will have to use the green and black pair. ![]() To make the movement we need to magnetize the coil. In NEMA 17 all pins are connected internally with the coil. The time required to make the coil fully magnetic depends on the induction of the coil. ![]() The rotation of the motor requires the magnetic field to make a single step. Actually, the torque depends on multiple factors, which are applying current, voltages and the third factor is the induction of coil within the motor. NEMA 17 torque-speed is changeable by applying the different operating speeds. In low-speed devices which require smart rotatory movement at a specific speed without missing any single step can use the NEMA 17. It is suitable for 3d printers, CNC Machines, Engraving Machines, Robot Arms, etc. They are commonly used in CNC machines, Robotics, 2D and 3D printers.įor this guide, we will use a NEMA 17 stepper motor and control it through a DRV8825 Driver Module. That means a complete revolution of a stepper motor is divided into a discrete number of steps. Unlike other DC motors, they provide a precise position control according to the number of steps per revolution for which the motor is designed. They rotate in discrete steps of predefined values and are able to rotate both clockwise and anticlockwise. ![]() Stepper motors are DC brushless and synchronous motors.
