Learn how to combat the mechanical losses and parasites that the electric motor shows
The electric motor suffers from four different losses that are classified as electrical losses, magnetic losses, mechanical losses and parasitic losses.
The electric motor mechanical losses occur when there is friction procedures, losses due to air opposition, and also ventilation. For this electric motor of the problem is reduced it is necessary to increase the iron section of both the rotor and in the stator and it changes when procedures with low friction and when the ventilation system is perfected.
When the parasitic losses occur, they are also called stray losses and occur due to the leakage flux, the current distribution is not uniform, mechanical imperfections in the openings for air flow and also when there are irregularities in the airflow density and to be drained through the openings.
This problem can be combated with the optimization of electric motor design.
