Before recycling the individual materials must be separated. Most important components are grey cast iron
(housing), steel (shaft, stator and rotor sheets, consumables), aluminium (rotor), copper (windings) and plas-
tics (insulation materials like for example Polyamide, Polypropylene and others). Electronic components like
printed circuit boards (inverter, encoder, etc.) must be recycled separately.
Terminal board connections
In standard design surface cooled motors are adapted for both rotational directions.
The connections U1, V1, W1 at phases L1, L2, L3 (in alphabetical or natural order) result always in clock-
wise rotation. The sense of rotation can be reversed at direct starting if two main connections at the terminal
board are changed.
For a machine with only one shaft end or with two shaft ends that have different diameters, the sense of
rotation is that rotational direction which is seen, if a person looks at the front end of the only or thicker shaft
end.
For each motor the correct connection diagram is attached. The connection must be done
accordingly. For the connection of auxiliary circuits please see the additional connection dia-
gram, which is also attached.
