🔧 What is a Nidec Speed Reducer?
A Nidec speed reducer is a mechanical device designed to reduce the rotational speed of a motor while increasing its torque. Nidec is a well-known Japanese company that manufactures high-quality motors and gearboxes, including speed reducers, under several subsidiaries like Nidec-Shimpo, Nidec-Graessner, and Nidec Drive Technology.
Speed reducers are commonly used in automation, robotics, conveyors, and other motion control systems.
