PHB42E series hybrid stepper motors are supplied by one of the China's top stepper motor suppliers (PrimoPal Motor). These NEMA 17 square stepper motor with 3.6° step angle (100 steps/revolution) are made of high-quality cold rolled steel sheet and anti-high temperature permanent magnet. The body length of PrimoPal's standard-verion NEMA 17 stepper motors is 34mm, and the holding torque could be as high as 12N.cm (17.0oz-in). These high-performance and high-reliability NEMA 17 stepper motors are terminated with four or six flying ended lead wires, and could be easily connected to the constant current or chopper drive controllers.
