Motor assembly

6.1 Motor assembly

The following should be observed when routing and connecting up motor supply cables:

The minimum bending radii (see "Electrical connections") for moving power cables must be observed (see catalog NC 60).

The cables may not chafe anywhere.

The cables should be permanently routed and fastened at 200 mm intervals.

When PELV cables with open cable ends are connected, the requirements of electrical separation (to EN 61800-5-1) must be taken into account.

6.1.4Checking the work carried out

Checking the installation work

Once installation has been carried out, make sure that the rotor can move without hindrance. Before doing so, remove all tools and objects from the area of the rotor and air gap.

DANGER

Electrical shock hazard!

Before the motor is rotated, the power connections must be properly connected and insulated.

The mounted rotary axes must always be able to move without hindrance. Examples of axes that cannot necessarily be checked by hand:

Large axes with a high friction torque

Blocking in a current-free state

Uneven weight forces

DANGER

Risk if axes moves in an uncontrolled manner.

Take care when removing a block or releasing a brake when the motor when is disconnected from the power supply and in an uncontrolled state.

All supply cables must be routed and secured in such a way that they cannot be bent, damaged, or pressed against rotating parts.

Coolant supply ducts must be easily accessible and the coolant must be allowed to flow freely.
