9.9 Design of Rotor and Assembly Principle of Rotor/Spindle
Shaft
The rotor and the spindle shaft are connected to one another with a
shrink fit. The rotor can be designed in two ways:
• rotor with smooth bore (type code designation 1N)
• rotor with step interference fit (type code designation 2N)
The following descriptions provide an approximate overview of the
required assembly steps for connecting the rotor to the spindle shaft.
You can find detailed information regarding the assembly of IndraDyn H
motors in chapter 11, “Assembly Instructions”.
