2.2.2 Operations
1. Preheating rotor and ring, and refrigerating shaft
• Preheat rotor and ring to 140°C-150°C. Cool the shaft less than 0°C.
• The rotor temperature must be measured directly, and the maximum temperature never exceed 150°C.
If the rotor temperature exceeds 150°C, the rotor will be damaged.
2. Shrinking fit
• Mount the ring, rotor, ring, quickly and without a break.
•
The ring has a front side and back side. The side which
has a step is the side to the rotor.
3. Figure of completion
•
Gradually cooling.
WARNING
There are several dangerous operations. Be careful for the high temperature and a heavy object. Be careful for the strong magnetic force of the rotor.
There is danger that magnetic metal (e.g. Iron) is crashed by strong magnetic force. Therefore do not bring them close to each other more than 50cm.
When the rotor is put for the preparations of work temporarily, please wind corrugated cardboard or a buffer material around rotor surface more than 30mm, and rope off the rotor,
call attention that the rotor has strong magnetic force. to keep away from a person to access the rotor.

CAUTION
The rotor has strong magnets inside. So
please be careful to its magnetic force and
influence of the magnetic field.
