The Nema-17 Stepper motor

The NEMA-17 Stepper motor

The Nema-17 motor is a widely used bipolar stepper motor that is used in various applications. It is characterized by a Nema-17 flange size, which means that it has a square housing with an edge length of 1.7 inches (42.3 mm). These motors are known for their precision and controllability and are often found in 3D printers, CNC machines, robots, and other applications where precise positioning and movement are required.

The exact specifications of a Nema 17 stepper motor can vary depending on the manufacturer and model, but here are a few typical specifications.

The motor has a step angle of 1.8 degrees per step (200 steps per revolution) and a holding torque in the range of 0.2 Nm to 0.59 Nm or more.

The current is usually between 1-2 amps per phase and the motor requires a voltage of 12 to 24 volts.

The shaft has a diameter of 5 mm and the weight is usually in the range of 200 to 300 grams.

The Nema-17 motor has the advantage that it is relatively compact and still offers sufficient power for many applications. They are also generally inexpensive and readily available, making them a popular choice for hobbyists and professional applications.

In the following, we will operate the motor with different stepper motor drivers and learn about the respective differences in application and current limitation.
