The installation dimension sheets in "Chapter 4, Dimension sheets" provide
additional instructions and recommendations about general motor assembly.
For this reason, the figures also show parts that are required but are maybe
not included in the Bosch Rexroth delivery and have to be appropriately di‐
mensioned and provided by the user. Including:
●
Motor encoder
● Spacer sleeve (for rotor assembly)
● Clamping ring and clamping plate (for rotor assembly)
We recommend to follow the steps described below for motor assembly:
1. Mount the stator to the machine.
2. Connect rotor and spacer sleeve to the clamping plate.
3. Position the rotor with spacer sleeve on the shaft and fasten it with a
clamping ring.
4. Attach the motor encoder.
5. Mount the housing lid and the encoder cover.
6. Make the electrical connection and the coolant connection.
12.7.2 Dimensioning the shaft end
Maybe the rotor is not coaxially installed in the stator, due to installation toler‐
ances of the system. During operation, radial forces may therefore act in the
motor and, thus, also on the shaft end to which the rotor is mounted.
To ensure sufficient stiffness of the drive system, the following factors must
be taken into account during dimensioning of the required shaft diameter:
●
Required minimum air gap after assembly of rotor and stator
● Radial forces acting during operation due to the permanent magnets on
the rotor (see the table below)
● Weight of the rotor and where applicable further radial forces acting de‐
pending on the particular application
the following dependencies are taken into consideration:
Therefore, the shaft diameter (see
Table 12-2 ) have to be dimensioned tak‐
ing the bending of the shaft into account, the air gap S

never falls below the
minimum value after installation between rotor and stator.
