Temperatures evaluation in an integrated motor drive for traction applications

The integrated propulsion motor is a drive designed for an individual self-driven container rail-platform wagon developed in the ldquointegrated standard transport unitrdquo research and development project, supported by the European commission. This paper presents the study of the motor and the converter temperatures at rated and overload working conditions. The problem is afforded by combining the simulation (finite-element method and lumped-parameter models) and the experimental approaches. For this purpose, a dedicated experimental setup has been designed and realized.
