Rotor Testing Machine For Die-Casting Aluminum Rotor Of Electric Fan

1. Test introduction

• Test object: die-casting aluminum rotor of electric fan
• Test Items: the quantity of broken bar, thin bar, the total number of conducting bar, the slot deviation angle

2. Rotor testing machine introduction

• The quality of squirrel-cage rotor affects the motor performance, and the rotor aluminum quality depends on the technology parameter, rotor iron core, the model preheating temperature, aluminum liquid temperature and chemical material.
• The problem of broken bar, thin bar and porosity are universal in the production line, which can lead to increasing the resistance, consumption, slip ratio, low efficiency and high temperature.
• The rotor testing machine mainly tests the quality of die-casting rotor, by which the fault of die-casting can be tested quickly.

5. The effect of the quality of rotor

• Low efficiency, high temperature, high slip ratio and increasing resistance are caused by the rotor porosity.
• The thin bar increase the resistance and decrease the start torque
• The porosity increases the resistance, lower efficiency, increase the temperature and slip ratio.
