[When indicating a maximum surface temperature: for zone 2 (gas):
total surface including rotor and windings; for zone 21, 22 (dust): outer surface (enclosure, shaft)!]
Motors with double identifi cation are only
intended for use in gas or dust explosive
atmospheres. Use in hybrid mixtures must
be checked and approved separately.
Generally notes for operating motors driven by
frequency converters
Commissioning of explosion-proof asynchronous motors
driven by frequency converters is only allowed if the mo-
tors are specially designed, produced, tested, certifi ed
and marked for this purpose. Especially attention has to
be payed to the notes of the producer. A suitable choice
of the frequency converter and/or the use of fi lters have
to secure that the maximum allowable pulse voltage at
the motor terminals will not be exceeded.
The following values of the maximum pulse voltage
have to keep according to series and options:
Series K11./K10./K12./K21./K20./K4.R/W.1R/W.2R
Size 56-132T 1) Û ≤ 1000 V
Size 56-132T 1) acc. to Sp.2945 Û ≤ 1350 V
Size 132 [K20. 112] up to 400 Û ≤ 1350 V
Series KU1./KU0./KU2./WU1R/WU2R 2)
Size 56-132T 1) acc. to Sp.9382 Û ≤ 1560 V
Size 132 [KU0. 112] up to 400 Û ≤ 1800 V
Series KV1./KV4./KV0./KV2./WV1R/WV2R 2)
Size 132 [KV0., KV4. 112] up to 400 Û ≤ 2500 V
1)
132T… Size 132 produced by VEM motors Thurm GmbH
2)
The marking of the series K11./K10./K12./K21./K20./K4.R/
W.1R/W.2R with suffi xed TU or TV is possible with certain
designs.
It has to be guaranteed that the supply voltage at the
motor terminals (keep into attention the voltage drop
over the used fi lters) in any case has to be equal to the
data at the name plate of the motor.
If the voltage at the terminals of the motor is smaller
than the rated voltage at the name plate because of
voltage drops at the frequency converter, the cables,
reactor coils or fi lters the rated frequency has to be
lowered in relation with the voltage drop. This measure
results in a smaller variable speed range.
