18.1 Skilled Technical Personnel
Any work on the system and on the drives or in their vicinity may only be
carried out by appropriately trained technical personnel. The owner of the
system must ensure that all persons carrying out
• installation work,
• maintenance measures, or
• operation activities
on the system are adequately familiar with the contents of this
documentation as well as with all warnings and precautionary measures
contained therein. Qualified technical personnel must have been trained
and instructed and are authorized to activate and deactivate, ground and
mark electric circuits and equipment according to the safety rules and
regulations. Qualified technical personnel must possess the appropriate
safety equipment and have been trained in first aid.
18.2 Mounting the Motor
Observe all warnings and safety advice mentioned in Chapter 3. This
minimizes the risk of accidents and damage to the system or the motor.
Execute all handling instructions very carefully. This ensures correct
mounting and dismounting of the components.
MHD motors comply with design B5 in accordance with DIN 42950, Part
1, ed. 08.77. Please refer to the dimensional sheets in Chapters 6 to 13
for all relevant dimensional details.
Before mounting:
1. Procure tools, auxiliary materials, measuring and test equipment.
2. Check all components for cleanliness.
3. Check the components for visible damage. Defective components
may not be mounted.
4. Ensure that mounting can be done in a dry and clean environment.
5. Ensure that the holder for the motor flange is without burrs.
6. Check whether the motor holding brake reaches the holding torque
specified in the data sheet. Should the brake fail to reach the torque
specified, first grind in the holding brake as described under the
“Holding Brake” section in Chapter 19. Then proceed as follows:
7. If you intend to use a liquid-cooled motor, establish the liquid
connection and check the coolant lines for tightness by exerting a
pressure of 5 bar. Also ensure that the flow volume required flows
through the motor.
Mounting the MHD motors:
Mount the motor. All of the measures and tolerances specified in the
dimensional sheets must be kept.
To fix the flange, we recommend to use the screws and tightening
torques listed in the table below.
