a gear unit is required to convert the torque and speed of an upstream electric motor so that they meet the technical drive requrement of an application. for that reason, the gear unit is the central component of a gear motor

based on the design, size, and gear unit stage, a gear unit transform the speed of a motor into steps up or steps down. the resulting speed ratio between the input speed and output speed is therefore one of the most importatnt characteristic values of a gear unit. how powerful a gear unit is and the loads that it can convey depends on its maximum torque, measured in the physical unit newton meters
