Experimental Validation of a Simple Multiphysics Model for Drum Roller Driven by Induction Motor

This paper presents an efficient multiphysics analysis (electromechanics coupled with thermal) of a drum roller that is driven by a 3-phase induction motor. The drum roller performance at variable load can be accurately predicted using a simple non-linear equivalent electric circuit coupled with a customized load profile and a reduced thermal network. The multiphysics analysis is focused on the main problems related to the drum roller operation: stator current variation when a random load level is present and heat extraction via the drum shell and conveyor belt.
