The OMGB Gearbox Ome Motors series consists of speed reducers characterized by high power density, reliability, modularity, compactness and an excellent performance/robust ratio.
An electric motor reducer - also called a speed reducer or speed reducer - is a mechanical system that transmits power to the shaft, modulating it as needed.

A speed reducer consists of a gearbox, i.e. a container housing a series of gears responsible for reducing the speed of rotation from an input shaft - called a fast shaft - to an output shaft - called a slow shaft. In fact, therefore, the gearbox functions as a speed and torque converter and, combined with a motor, constitutes a geared motor.

The birth of the gearbox for electric motor is due to the German entrepreneur and designer Albert Obermoser, who in the second decade of the twentieth century patented the so-called Vorlegemotor, whose basic model consisted of an electric motor combined with a simple speed reducer. Since then, of course, the basic model has been gradually improved and new models have been created.

A speed reducer for electric motors can have various types of operation. In particular it is possible to distinguish between:

• Direct current (DC) powered gearbox: it is able to convert electrical energy into mechanical energy by modifying the motor speed through the variable supply voltage;
• Alternating current (AC) gearbox: is any type of speed reducer combined with an alternating current powered motor capable of producing electrical energy functional to the lowering of speed in order to increase the power of the instrument.
