Devices for joining the rotor
The following devices may be required depending on the joining process.
Joining with the heat process (shrink fit)
Joining with the cold process (stretch fit)
• Hot-air oven with temperature monitoring - suitable for
installation temperatures
1)
• Oven volume appropriate for the rotor type, placement of
the oven in the immediate vicinity of the workplace
• Air-conditioned room or cold chamber for tempering the
spindle shaft and rotor core
• Dewar vessel with liquid nitrogen N2 (-195.8 °C)
• For a small workspace: good ventilation
1) The temperatures for the installation can be found in the "Installation temperatures" Cable
in chapter "Mounting the rotor (Page 98)".
Hoisting gear for transporting the components
Hoisting gear, gripper, load suspension device, see figure "Examples for transporting
components"
● Carrying capacity dependent upon the rotor core weight (please refer to the rating plate
for the weights)
● Preferably with a device for quick lowering
Transport of the heated rotor core
