Maintenance work

Performing maintenance work on the motor
Note
It is essential that you observe the safety information provided in this documentation.
As a result of their inherent principle of operation, the motors are always wear-free.
To ensure that the motor functions properly and remains free of wear, the following
maintenance work needs to be carried out:
• Regularly check that the rotary axis is free to rotate.
• Ensure perfect operation and that the power losses are adequately dissipated.
– Keep the air gap free of metal chips and particles.
– Keep pollution and dirt away from the motor space, e.g. metal chips and oil.
– Clean the motor, depending on local degree of pollution.
• Regularly check the general condition of the motor components.
• Check the current drawn in the previously defined test cycle.
• Check the cables to ensure that they are not damaged and are not worn. Never use
electrical devices and equipment with damaged cables.
• Make sure that the cable glands are secure.
Intervals between maintenance
Since operating conditions differ greatly, it is not possible to specify intervals between
maintenance work.
Indications that maintenance work is required
• Dirt in the motor cabinet
• Distinctive changes in the behavior of the machine
• Unusual sounds emitted by the machine
• Problems with positioning accuracy
• Higher current consumption
