Product Details
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.
