3.3 Service life
The service life of the motors when operated correctly is limited primarily
by the bearing service life.
The following operating conditions can significantly reduce the service
life:
• Installation altitude more than 1000 m above m.s.l.
• Continuous operating temperatures greater than 80 °C
• Movements of less than 100 °
• Operation with very high angular acceleration
• Operation under vibration load greater than 20 m/s

• High cycle frequencies
• Allowing sealing rings to run dry
• Contact of the motor with aggressive media
• Condensation and icing
• Exceeding the permissible shaft load
