Intelligent Thermal Motor Protection with the Basler BE1-11m Motor Protection System
The largest contributing factor to motor failure is excessive motor heating. The life of the motor is shortened if the winding temperatures are allowed to exceed their insulation class levels for a significant amount of time. It is usually assumed that, for every 10°C above the design temperature limit, life of the motor is reduced by a factor of two. Therefore, aggressive application of intelligent thermal motor protection must be implemented to get maximum return on these very large and very critical capital investments.
Basler's newest Application Note - PC-11m focuses on the benefits of BE1-11m's excellent thermal overload protection and maximum setting flexibility. The Basler BE1-11m thermal model implementation has two unique features:
o The ability to tailor the 49 thermal model with the "overload" setting.
o The ability to set the thermal capacity at which the motor will perform an emergency start.
