Research Water Colling System Of The Synchronous Permanent-magnet Plane Motor

High-tech manufacturing toward high-speed, precision and modular direction with the advancement of technology, it made stringent requirements for positioning accuracy and speed in the manufacturing and processing equipment. Simple planar motor has the structure, rapid response, high sensitivity, making it widely used on a two-dimensional positioning device. But the plane of the motor heating power higher heat density, to ensure their normal operation and control accuracy, it is necessary to carry out researches on the motor cooling. The traditional way of air-cooled heat sink has been increasingly unable to meet the requirements of this high heat flux, while the water-cooled heat sink has been extensively studied because of its high heat transfer coefficient and high efficiency. Based on this, the paper is directed to a moving coil and permanent magnet synchronous motor design plane produced a water cooling system. Performed for the core component of the cooling system water cooler research, and for the design of the radiator to improve performance of the radiator is important, has a practical significance for the uniformity of the temperature of the reinforcing plane of the motor.Firstly, the research carried out for the water-cooled heat sink, based on the understanding of the structure of a conventional channel water cooler performance, that is, high flow channel structure of traditional series of water-cooled radiator cooling efficiency within the flow channel pressure loss larger, higher pump requirements. The traditional parallel flow channel water cooler low pressure loss, but its thermal efficiency is low and uneven flow rate of water in the channel. According to the foregoing and experience, it sums up how to improve the performance of a radiator, In order to improve the performance of the radiator, radiator enhanced temperature uniformity, this paper puts forward the water cooler the other three new flow channel structure, namely a series-parallel flow channel structure, dual series flow path structure and spiral flow channel structure. In order to verify the performance of various heat sink, it makes the CFD simulation for the different flow channel structure heat sink through the use of simulation software ANSYS Workbench. The simulation can be a heat sink temperature distribution and flow field distribution inside the heat sink, that analysis comparing the performance of the radiator, the conclusion is that the new heat sink overall performance is better than the traditional heat sink, and average temperature is best spiral flow channel structure heat sink.Finally, the overall performance is better and uniform temperature best radiator spiral flow passage structure, used in the actual Planar Motors. At first, it analysis the application of heat sink on plane motor, and then designs and completes a set of experiments test platform structures. What,s more, it does a research on thermal efficiency of spiral-type heat sink, and through experiments it finds heat sink flow and thermal performance characteristics under different inlet velocity, which can verify the feasibility of the proposed water cooling system. Furthermore, it does a comparative analysis of the experimental results and simulation results, and shows that the two maintained a good agreement with the results tendency to verify the rationality of the numerical studies, but also for water cooler provides an experimental basis in the application of the plane of the motor.
