3. Introduction
- The rotor testing machine mainly test the quality die casting of
rotor, which is rapid to test the failure of die casting rotor, for
example: broken bar, thin bar, porosity, leakage, squirrel cage
eccentricity, slot deviation, remanence, low quality of aluminum
alloy.
- The rotor testing machine is applicable to both laboratory and
production line, which can avoid the unqualified rotor produce and
outflow according to the test of die casting rotor. And it can
improve the production efficiency and product quality.

4. The influence of the rotor thin bar
The low efficiency, high temperature rise, high slip ratio and the
increasing resistance are caused by the thin bar of rotor.
5. Reason of thin bar
- Slot bottom conducting bar is not full of die casting due to the
high speed of centrifuge
- Aluminum water flow slowly caused by the small slot (in this
condition, the iron core preheating temperature need to be
improved).
- Wrong rotor lamination, slot line is not in a line, which block the
aluminum water flow.
- The iron core preheating temperature is low, and the fluidity
become bad when the aluminum water poured in.
