Drive Choke

DRIVE CHOKE

A choke is inductor which blocks higher frequency alternating current in electric circuit.  A choke is nothing but a coil of insulated wire wound on a magnetic core. Drive choke is used to reduce the impact of harmonics in variable frequency drive. As variable frequency drive is a non linear load creates harmonics which increases heating of the transformer and reduces capacity of cable and transformer. Input choke is a filter for variable frequency drive and output choke is used for the long cable.

Applications:
Choke is used for the protection against overvoltage on the line supply. It reduces harmonic distortion of the current produced by the drive. Choke also reduces short circuit current.

  • Protects drive.
  • Reduces Harmonics.
  • Reduces Short circuit current.
