![]() ![]() The wiring configuration varies depending on the motor model and manufacturer. Wiring Configuration: NEMA17 stepper motors usually have four or six leads, with each lead corresponding to a coil winding. Higher torque ratings enable the motor to handle larger loads or overcome resistance more effectively.ĥ. Holding torque refers to the amount of torque the motor can exert to hold its position when not in motion. Holding Torque: NEMA17 motors come in various torque ratings, typically ranging from a few Ncm (Newton centimeters) up to several dozen Ncm. To drive a bipolar stepper motor, an H-bridge or specialized motor driver is required.Ĥ. This bipolar configuration offers better torque and control compared to unipolar stepper motors. Bipolar Configuration: NEMA17 motors are typically configured as bipolar stepper motors, meaning they have two coil windings. However, microstepping techniques can further increase the resolution by dividing each step into smaller microsteps.ģ. They commonly have step angles of 1.8 degrees per step, resulting in 200 steps per revolution (full-step mode). ![]() Step Accuracy and Resolution: NEMA17 motors are known for their high step accuracy and resolution, allowing precise control over motor movements. ![]() The motors typically have a length ranging from 1.3 to 2.4 inches (33 to 61 mm), depending on the specific model and manufacturer.Ģ. Size and Form Factor: NEMA17 motors have a standardized flange size of 1.7 x 1.7 inches (43.2 x 43.2 mm), making them relatively small and easy to integrate into different projects. Key features of NEMA17 stepper motors include:ġ. These motors are widely used in various applications, including robotics, 3D printers, CNC machines, and automation systems. The term “NEMA17” refers to the motor’s standard size and mounting pattern, as defined by the National Electrical Manufacturers Association (NEMA). NEMA17 stepper motors are a popular type of stepper motor known for their compact size and versatility.
