PHB57M series hybrid stepper motors are supplied by one of the China's top stepper motor suppliers (PrimoPal Motor). These NEMA 23 square stepper motor with 0.9° step angle (400 steps/revolution) are made of high-quality cold rolled steel sheet and anti-high temperature permanent magnet. The body length of PrimoPal's NEMA 23 stepper motors ranges from 41mm to 76mm, and the holding torque could be as high as 150N.cm (212oz-in). These high-performance and high-reliability NEMA 23 square stepper motors are terminated with four, six or eight flying ended lead wires, and could be easily connected to the constant current or chopper drive controllers.
