Description
The objective of this project was to create, model and simulate in Comsol a linear motor (LIM) driven by a frequency converter with voltage control applied to the motor. A final speed of 100 m / s is established as a goal, so the maximum frequency and the voltage applied to frequencies higher than the nominal one must be recalculated (originally we created the motor for 40 m / s).
The power delivered by the motor varies from 50 to 30 KW at the point of maximum efficiency between 40 and 100 m / s, with maximum powers reaching 80 KW.
The maximum pushing force is between 1800 and 2000 Newton and the efficiency is between 90% and 95%
