Optimization design of water distribution platform for mine water-cooled permanent magnet explosion-proof motor
In order to study the effect of different channel cooling structures on the cooling performance of permanent magnet water-cooled explosion-proof motor,taking a permanent magnet water-cooled explosion-proof motor as an example,following the steps of motor design and through simulation of the motor,an axial Z shaped water channel water distributor structure is proposed to optimize the water circuit of the permanent magnet water-cooled explosion-proof motor.The 3D model of the initial motor model is established,and the temperature distribution of the motor under the rated load is obtained by finite element multi-physical field calculation.Based on heat transfer and fluid mechanics,the location,proportion and quantity of the water separating platform of the axial Z shaped waterway are studied.Through the CFD simulation of the motor and the finite element analysis,the temperature distribution maps of the motor under different conditions are obtained.Based on the actual situation and economic situation,the optimal solution for the cooling structure is obtained when the number of motor water distribution stations is 2.
