NEMA word defines the standard frames sizes of motor according to number with it like 14, 17, 21, 23, 34 and 43 etc. When we say Nema17 means it’s a stepper motor with some specific standard size Which is approximately 1.7 inches, means the width of motor is 1.7 inches from both sides like for Nema23 its 2.3 inches. NEMA number don’t define the height of motor. Nema17 comes in various heights color and appearance.
The bipolar (one winding per phase) stepper motors have four wires to connect to the motor. A basic 4-wire stepper motor have 2 coils in it which means there are 2 starting points and 2 ending points and we usually define them as A+, A-, B+ and B- and we call them phase too as we know 4 wire stepper motor is a 2phase stepper motor so it can be phase A, phase A’, phase B and phase B’. these days mostly Chinese stepper motor drivers are for bipolar motors means 4wire but in case you have 6 wire stepper motor drivers then you can convert your 4wire motor into 6 wire motor and vise, versa. There’s no difference between 4wire stepper motor and 6 wire stepper motor they both can we used with 4 wire stepper motor drivers because the 2 extra wires in motor are the midpoint of each coil which have its own benefits if we use it with 6 wire stepper motor drivers. Now come to the applications of this motor. Nema17 stepper can be used where we need to control the speed(rpm) with accuracy like 3D printers, small CNC machines, CNC routers, PCB milling machines, medical equipment and in various student projects etc.
NEMA 17 Stepper Motor 4 wire Bipolar is very useful in various applications, especially which require low speed with high precision. Stepper Motor NEMA 17 used in many machines such as 3D Printers, CNC Router and Mills, Camera Platforms, XYZ Plotters, etc. Stepper Motor NEMA 17 4 wire Bipolar is High precision 4–wire bipolar stepper motor, size in Nema 17, 1.8 deg. step angle (200 … is one of the most parameters for the stepper motor. You can use the A4988 or drv8825 driver to run this motor.
