separate them. The step interference fit loosens at diameter D1 first.
The o-ring keeps the oil from escaping.
After assembly, the rotor is balanced to the necessary vibration severity
grade (EN 60034-14:2004). To achieve equilibrium of the rotor, threaded
pins are radial screwed into the circumference of the balancing ring and
secured using glue.

Fig. 9-34: Stator installation principles
The stator is made up of an iron core with end windings located on the
front, two stator flanges and an integrated cooling system.
Construct the mounting bore in the spindle housing according to the
dimension sheets of the corresponding motor in chapter 5, “Dimension
Sheets”.
The stator is axially mounted on the corresponding side of the motor
spindle; it is then secured against movement. For this purpose, threads
for axial attachment have been provided on both ends in the stator
flange.
Note: It can be mounted to either the A or B side of the stator, but
not on both!
There must be a clearance of at least 1 mm between the stator and the
spindle housing on the end opposite of where the stator is attached so
that the stator can expand in length. The longitudinal expansion is
caused by the stator heating up while the motor spindle is operating
