Experimental Measuring And Numerical Simulation Of Cooling Fans For Large Scale Electrical Motor

At present, domestic air cooling electrical motor has excellence of oversimplified structure and convenience of manufacture, but compare with overseas high efficiency electrical motor there are some disparities. The causation of the disparity is large power dissipation of cooling fans of electrical motor.Cooling fans are the indispensable parts for ensuring the tranquilization and standing working of electrical motor. The function of cooling fans for electrical motor is ensure the air continual fan the part of electrical motor and make the heat apart from it. The air must conquer the resistance from electrical motor itself, cooler and vent-pipe, therefore the electrical motor can be secure and effective operation at defined temperature.We will conduct a series of wind tunnel experiment on a ventilator...
