This is a 57mm ultra-thin pancake stepper motor (low profile flat stepping motor), 2-phase bipolar type with 1.8° step angle. Thanks to its slim pancake structure and light weight of just 75g, it is specially designed for equipment with limited installation height. Low rotor inertia enables fast response, smooth rotation and high positioning accuracy.
