Introduction
General technical specifications
VIK design
■
Overview
On request, three-phase motors of the LOHER CHEMSTAR 1PS
and SIMOTICS XP 1MD5 series can be designed in accordance
with VIK guidelines ("Verband der Industriellen Energie- und
Kraftwirtschaft e. V.", the Association of the Industrial Energy and
Power Industry). VIK motors have the same power as the motors
of this list, but also satisfy the VIK recommendation both
mechanically and electrically. The most important points of the
minimum design to the VIK recommendation of March 2011 are
outlined in the table below.
VIK recommendation
Execution 1PS. or 1MD5
Motor enclosure and terminal box in cast-iron,
steel is permitted for frame size 355 and above
LOHER CHEMSTAR in cast-iron as standard
LOHER VARIO in steel as standard
Standard temperature range -20 to +40 °C
Standard
Paint finish suitable for industrial climates with corrosive gases and
vapors
Paint system N14A or higher quality
Fan covers must be designed with corrosion protection
Fan cover of zinc-plated sheet steel or increased wall thickness
The motor compartment must be protected to prevent any
small parts entering through the terminal box
Flexible implementation for 1PS0 and 1PS1. For 1PS5 and 1MD5 this
separation is standard due to the Ex type of protection.
Terminal box of minimum size and rotatable 4
90°, observe derating
factors regarding the load on cables and wires
The required size and conductor cross-sections as well as rotation
capability correspond to the standard design of 1PS and 1MD5, wire
cross-sections are adapted
Nominal bearing lifetime 40000 h for coupling drive, the grease lifetime
can be different or use of relubrication device
Standard for 1PS and 1MD5
Flat grease nipples are used with relubrication device
Efficiency at least IE2 also for explosion-proof motors
Standard
Defined noise emission limits
Standard
Motors in explosion-proof enclosures and optionally selected
PTC thermistors must be designed for sole protection
1PS5 and 1MD5 with PTC thermistors (
A11
) are designed for VIK (
K30
)
with sole protection (no converter rating plates).
In larger industrial motors, sole protection is only provided and stamped
as such for converter operation.
For converter operation, the bearing at NDE must be insulated in frame
size 315 and above
Options for converter operation are not included in the VIK options
and must be ordered separately. If line-operated motors with
explosion-proof enclosures and PTC thermistors are subsequently used
for converter operation, insulated bearings must be retrofitted by the
customer.
Motors in type of protection Ex d must be constructed with Ex e terminal
boxes and must fulfill IIC type of protection in frame size 315 and below
Standard
Minimum requirements for the documentation
Documentation is not included with the VIK design (
K30
or
W09
) and
must be ordered separately
