Geared motors with fractional power

Leroy-Somer's extensive experience in all areas of "industrial" power and drive transmission has led it to develop a highly comprehensive range of geared motors for "fractional" power. These products must provide the user with the same level of satisfaction (i.e. reliability, performance, etc.) as the "industrial" products. whilst still meeting the specific needs of the "fractional" market. Specialised units from the Leroy-Somer group have therefore been set up to design and manufacture these products (motors and gearboxes). All the gearboxes shown in this catalogue have components that...

Apart from the basic choices regarding the slow speed, output torque, motor supply type, it is important to know accurately its exact use and operating type in advance. The selection of a gearbox or a geared motor should take account of the application: The usage class is defined by the daily operating time and the type of application, according to the table below: Application class ALL RAPID SELECTION CHARTS IN THIS CATALOGUE ARE SET UP FOR OPERATING IN CLASS I (KP > 1 - equivalent to the Agma I class). The table below summarises the relationship between the “Agma” class and the duty...
