Motor chokes 1 phase
TM Motor Chockes are used in drive motors with
frequency converters. They are connected to the frequency converter's
output if the cables between the converter and the regulated motor are
long. They suppress adverse effects of capacitance represented by long
cables.The capacitive component of the cable impedance, with respect to
the power transistors switching frequency of the converter, may cause
overload on the converter output, failing to supply the nominal current
to the load. In addition to suppression of these effects, at the same
time it will reduce the radiation of EMI voltage both: on converter
output and on supply network direction. Insertion of motor chokes
prescribes to the manufacturer of converters for motor cable lengths
greater than 20-50 m depending on the type converter. Motor chokes are
designed so that their voltage drop is not higher than 2% of output
nominal voltage with the frequency 50Hz and with output voltage of
converter 3x400V/230 V. For standard realization the limit modulation
frequency of the converter is 3kHz. In case of requirement the higher modulation frequencies, please contact
the
manufacturer. One-phase motor chokes are normaly applied when specific dimensions are required where three-phase motor chokes can't be used.
