17HS8401S NEMA17 Stepper Motor (48mm):

The 17HS8401S NEMA17 stepper motor with a 48mm body length is a widely used stepper motor known for its versatility and compatibility with various applications. Here's a breakdown of its specifications and features:

1. Size and Mounting: The NEMA17 designation refers to its standardized dimensions established by the National Electrical Manufacturers Association. The "17" denotes the faceplate size, which is approximately 42mm x 42mm. This motor has a body length of 48mm, which specifies its overall length from the mounting face to the rear end.
2. Step Angle: This stepper motor typically has a step angle of 1.8 degrees per step, which means it requires 200 steps for a full revolution (360 degrees). This level of precision allows for accurate positioning and control.
3. Holding Torque: The holding torque of the 17HS8401S varies depending on the specific model and configuration. However, it's typically in the range of 40-60 N.cm (Newton centimeters). Holding torque refers to the amount of torque the motor can generate when stationary, providing resistance against external forces.
4. Bipolar Configuration: The 17HS8401S is a bipolar stepper motor, meaning it has two coils (or windings) per phase. It requires a bipolar stepper motor driver to control its operation effectively.
5. Voltage and Current Ratings: The voltage and current ratings of the motor determine the electrical parameters needed for proper operation. The voltage rating typically ranges from 2-5 volts per phase, and the current rating can vary from 0.4A to 1.5A per phase, depending on the specific model.
6. Applications: This stepper motor is suitable for a wide range of applications, including 3D printers, CNC machines, robotics, camera sliders, automated equipment, and more. Its compact size, moderate torque, and precise control make it versatile for various projects.
7. Compatibility: The 17HS8401S stepper motor is compatible with most NEMA17 mounting brackets, couplers, and other accessories, making it easy to integrate into existing designs or systems.
