With the popularization of permanent magnet linear synchronous motor (PMLSM) in recent year, the problem of temperature rise has attracted more and more attention since excessive heat generated in the windings could deteriorate the electromagnetic performance and limit thrust density. Thus, thermal analysis is an essential step of motor design. In order to solve this problem, a suitable method is...
For permanent-magnet linear motors (PMLMs), high-temperature rise can deteriorate their electromagnetic performance and limit their thrust output. A water-cooling system can be employed to reduce the temperature rise and to improve the thrust density. In order to study the thermal performance of a water-cooled, 14-pole, and 12-slot PMLM, a finite-element model and thermal network model are developed...
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...
In this paper thermal behavior of a 600kW 4200r/min interior permanent magnet synchronous motor (PMSM) with forced ventilation in the stator was analyzed using Fluent. Due to its high power density and compact structure, accurate thermal analysis of PMSM traction machine is of great importance in designing and optimizing. Different structures of stator ventilation are evaluated and the square ventilation...
