Overview
With the longest lifetime and highest reliability
Working to serve you
The frame and end shields are manufactured out of gray cast
iron. Advanced design methods result in a compact and rigid
frame with excellent damping characteristics. The gray cast-iron
frame in conjunction with highquality anti-corrosion protection
protect the motors against the effects of the weather over many
years.
The aluminum die-cast technology, which is used for the rotor
manufacturing, has the benefit of being extremely rugged due to
the form-fit connection between the rotor bars and laminated
core. Where mechanically necessary the proven design with
copper bars is used.
Proven technology
Well-proven MICALASTIC VPI insulation
A-compact PLUS motors have the MICALASTIC insulating sys-
tem that has proven itself over many years in high-rating, high-
voltage motors – and that worldwide. An important component
of this insulating system is the VPI technique (Vacuum Pressure
Impregnation) that is harmonized with the insulation design. This
insulation technique fulfills every requirement regarding:
•
Motors can either be fed directly from the line supply or a drive
converter
•
High switching and reversing strength due to the high stiffness
of the winding overhangs
•
Excellent corona shielding
•
In conjunction with the extraordinary mechanical strength and
thermal endurance, these factors ensure an extremely long
winding lifetime - even under tough environmental conditions.
Bearings with the highest reliability
The bearings of our A-compact PLUS motors are precisely
aligned to the speed, load and other operating conditions. The
motors are equipped with anti-friction bearings, or when techni-
cally required with sleeve bearings. They are well sealed to
make the motors insensitive to external environmental effects –
therefore playing a role in achieving the high degree of availabil-
ity and increasing the productivity of the overall plant or system.
The low maintenance costs also have a positive impact on the
operating costs.
Continuous monitoring
Even the most sophisticated motor can be exposed to opera-
tional conditions for which it was not originally designed.
Sensors and monitoring devices can continually sense the elec-
trical, thermal and mechanical operating data.
Terminal box
Overview of generally used main terminal boxes
Connection options
Auxiliary terminal box
•
The monitoring elements are connected-up in auxiliary termi-
nal boxes.
•
The auxiliary box is integrated into the motor frame.
•
The plate for connection will be sealed with a plate of steel, ac-
cording to IP55.
•
The position as standard is on the right hand side. Left or right
side is possible, independent of main terminal box.
•
2 openings for cable glands size M25 x 1,5 are standard, they
are closed with plugs.
