Churning losses and thermal rating

• A mounting position where the first gear unit stage is fully immersed in the lubricant. The corresponding mounting positions of the gear units are marked with an * in the "MOVIMOT^® advanced.." catalog > Chapter "Mounting positions of MOVIMOT^®advanced gearmotors".
• A high mean input speed and consequently a high circumferential speed of the gear wheels of the input gear stage.

If one or both conditions apply, determine the requirements from the application and the corresponding operating conditions (see chapter Data for calculating the thermal rating) and contact SEW‑EURODRIVE. SEW‑EURODRIVE can calculate the thermal rating based on the actual operating conditions. The thermal rating of the gear unit can be increased by appropriate measures, such as by using a synthetic lubricant with higher thermal endurance properties.

INFORMATION

To keep churning losses to a minimum, use the gear unit preferably in mounting position M1.
