“…Switched reluctance linear launcher has also the well applied foreground for electromagnetic launcher with its high reliability and high fault tolerant capability [6]- [10]. The electromagnetic loss causes the temperature rise in switched reluctance motor [11], and the power losses of power transistors and freewheeling diode including switching losses and on-state losses causes the temperature rise in power converter. The power converter is the weakest part of the drive system.…”

This paper presents a temperature rise simulation model of power converter for switched reluctance linear launcher. The accuracy of the model is verified by comparing experimental results with simulation data. Furthermore, three types of power switches arrangements and two PWM chopping schemes are studied with the present model for reduction of the maximum temperature rise. It is shown that the PWM chopping alternately scheme, the upper row power switches and lower row power switches installed on the two sides of midline of the heat sink contributes to the decrease of the maximum temperature rise of the power converter.

“…Many studies about thermal analysis have been carried out for rotating motors such as rotating induction motors [8]- [10], rotating reluctance motors [11] and rotating permanent magnet motors [12]- [14]. However, the thermal analysis of PMLMs is more difficult and poorly documented, primarily due to their special open structure, large modeling area (at least half of the entire PMLM), and complex working patterns (reciprocating acceleration/ deceleration running, short-time duty, intermittent duty, etc.).…”

For permanent magnet linear motors (PMLMs), large temperature rise can damage their performance and limit their output. Water-cooling system can be designed to reduce temperature rise and to improve thrust density. In order to study the thermal performance of a water-cooled, 14-pole, 12-slot PMLM, the finite element model and the thermal network model are erected. For water-cooled type PMLM, the modeling difficulties are solved. Under continuous duty, the temperature distribution of this PMLM is investigated based on the two models, which is validated by experimental results. The effect of water-cooling system and the impact of its parameters on temperature rise are investigated. And, the influence of temperature rise on motor thrust force, and efficiency is studied. Finally, based on the finite element model, thermal characteristics of this PMLM under shorttime duty and intermittent duty are studied, which find the relationship of running time and the maximum allowed short-time current, and the impact of load sustained rate.
