GRMOT's two-phase brake-equipped stepper motors feature high torque, low noise and precise positioning, combining the advantages of permanent magnet and variable reluctance technologies. The matching stepper motor drivers support microstepping control and strong anti-interference performance, and are compatible with pulse signal speed regulation. Working in synergy, the motor-driver combinations are widely used in industrial scenarios such as 3D printing, numerical control (NC) equipment and automated production lines, ensuring efficient and stable operation of the equipment.
