Motor damage due to penetration of liquids!
If motors are attached according to IM V3, fluid present at the output shaft
over a prolonged time may penetrate and cause damage to the motors.
Ensure that fluid cannot be present at the output shaft.
3.5 Installation space
Self-cooling of the motor should not be prevented due to the installation situa‐
tion.
3.6 Output shaft
Smooth shaft
MSM motors offer a non-positive shaft-hub connection without play with ex‐
cellent running smoothness. Use clamping sets, clamping sleeves or tension‐
ing elements to couple the machine elements to be driven.

Shaft with keyway
MSM motors with keyway allow form-locking transmission of torques with
constant direction and low requirements on the shaft-hub connection. The
keyway is not in the scope of delivery.
