Stop!
ƒ The motor will be destroyed when the maximum motor speed is exceeded
ƒ Do not exceed the maximum torques specified in Tab. 2!
– Torques as high as indicated can be reached through appropriate
motor−controller combinations.
– Excessive torques might result in a break of the motor shaft!
)
Note!
ƒ Excessive axial and radial forces reduce the bearing service life.
– Observe the permissible forces to Tab. 2!
– Calculation basis:
Bearing service life L

The permissible continuous power is calculated as follows:
P ’ = k υ
