Industrial Gear Motors
NORDBLOC Industrial Gear Unit - Modular system for
more flexibility
NORD industrial gear units have been developed according to the
tried-and-tested unicase housing principle. The unicase is a one-piece
housing, into which all the bearings are integrated. The finishing of this
unicase is carried out with in unique jig, on state-of -the-art CNC
machines. The unicase concept features highest levels of precision, rigidity
and strength. There are no dividing seams between the drive and the gear
unit housing which are subjected to transverse forces or torque. The unicase
principle allows the shaft axes to be staggered, resulting in a more compact
design which allows the use of larger roller bearings to guarantee a long
operating life.

IE2 MOTORS
Energy consumption of electric drive units
In industrial applications, electric drive units are responsible for between
30% and 40% of all electrical energy generated. Optimisation of efficiency
for the entire drive system including the application/process is a
significant factor – the potential is typically about 30% to 60%.
|
|
|
|
Energy saving
IE2 have a greater efficiency than the previous EFF2
motors.
- IE2 motors produce less waste heat
- IE2 motors have a longer operating life than previous normal motors.
- IE2 motors help to reduce operating costs
- IE2 motors allow the use of smaller sizes due to greater efficiency.
- IE2 motors enable "safety reserves" to be dispensed with due to the shift
of the operating range or the safety range above the nominal rating.
Exception for high switching cycles (S4/S5) as due to the greater inertia of
the rotor, more energy is required for start-up.
|
|
EFFICENCY-OPTIMISED IE2 MOTORS
The efficiencies required by the new standards can only
be achieved by the increased use of materials and more sophisticated
production techniques, as the manufacturing optimisation of the sheet metal
stampings is largely exhausted.
NORD uses a 3-Point concept:
- Use of more active material
- Use of higher quality sheet metal with less losses
- Increase of the copper filling factors with simultaneous reduction in size
of the winding heads through optimised production processes
This results in increased efficiency of the motors, less production of waste
heat and an increase in the operating life of the motors. In addition,
economic benefits may result (e.g. though the use of a smaller motor).
|
|
IE3 ENERGY-SAVING MOTOR
By using copper as the conductor material for the
squirrel cage instead of aluminium, rotor losses are considerably reduced.
This results in the following differences compared with the aluminium motor:
The slip under load, which is proportional to the rotor losses, is
considerably less. The torque curve in the operating region is considerably
steeper. The breakdown torque is attained with a lower slip. The starting
torque, which is proportional to the rotor losses, is considerably lower.
Compared to the aluminium motor, in the energy-saving motor with a copper
rotor, an increase in the amount of iron is only necessary to a moderate
extent, or can be dispensed with entirely. However, the sole use of copper
is not sufficient. Stampings with lower specific core losses, larger
conductor cross-sections in the windings and flux-optimised windings, and
smaller winding heads are also important components of this design.
