Design and Analysis of in-Wheel Permanent Magnet Synchronous Motor Cooling System of Mining Dump Truck

Abstract:

In-wheel motor is an important power unit of electric drive mining trucks, a variety of dynamic performance and thermal issues have important impacts on the whole vehicle performance. In this paper, a model of permanent magnet brushless DC motor (BLDC) cooling system with water-cooled stator structure of electric drive mine dump truck is built. Considering the actual cooling systems, the author modeled the bldc motor and completed the electromagnetic simulation with ansoft software to determine the motor heat source and boundary conditions. This paper simulates the cooling water jacket temperature field with fluent software, and finally validated the feasibility of the design of the motor and its cooling system by experiments.
