High Torque 20x20mm Stepper Motor

PHB20Y series hybrid stepper motors are supplied by one of the China's top stepper motor suppliers (PrimoPal Motor). These NEMA 8 square stepper motor with 1.8° step angle (200 steps/revolution) are made of high-quality cold rolled steel sheet and anti-high temperature permanent magnet. The body length of PrimoPal's NEMA 8 stepper motors ranges from 28mm to 40mm, and the holding torque could be as high as 2.4N.cm (3.40oz-in). These high-performance and high-reliability NEMA 8 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.
