The Pacific Scientific POWERMAX II M Series motors with SIGMAX technology represent some of the most powerful steppers available. These 2-phase NEMA 23 sized hybrid stepper motors offer high torque per motor size, ranging from 0.67 to 1.79 N-m (95 to 253 oz-in) nominal holding torque, and speeds up to 3,000 rpm. They feature a polymer encapsulated stator for excellent thermal dissipation and a polymer end bell with threaded inserts, enhancing cooling efficiency and providing flexibility for mounting encoders and brakes. Exposed laminations further improve thermal dissipation, contributing to longer motor life.
