Rotor Testing Machine For Die-casting Aluminum Rotor Of Washing Machine

1. Test Introduction

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

2. Rotor 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 and slip ratio, low efficiency and high temperature.

3. Technical specification

4. Defection analysis of die-casting aluminum rotor

• Sand hole: the die-casting rotor was filled with sand hole internally or surfacely.

• Porosity: all size of porosity locates everywhere in the inner or surface of the die-casting model, the porosity is a spherical or almost spherical hole with smooth wall generally.
