A NEMA 17 stepper motor with a torque rating of 450mN.m (millinewton meters) and a ball screw mechanism is a suitable choice for various applications that require moderate torque and precise linear motion control.

A torque rating of 450mN.m indicates the motor's ability to provide rotational force. This level of torque can handle moderate loads and is commonly used in applications such as small CNC machines, 3D printers, automation equipment, and other systems that require accurate positioning and controlled linear motion.
