Iron output reactors for AC operating mechanisms

Output reactors are used on the load side of frequency converters and motor currents flow through them.

Output reactors compensate capacitive charge-reversal currents with long cables and, in the case of long motor cables, limit the dv/dt at the motor terminals. This enables the use of longer motor supply cables:

• 200В m shielded motor cable
• 300В m unshielded motor cable

Use of iron-core output reactors:

• Operating mechanisms with standard and trans-standard asynchronous motors and a rated motor frequency (field weakening frequency) of up to 87 Hz and a maximum frequency of 200 Hz.
• Operating mechanisms with reluctance or permanently excited synchronous motors with a maximum frequency of 120 Hz.

Note on the versions Standard (Catalog LVВ 60):

The following generic parameters apply, which must not be exceeded:

• Maximum motor cable length 200 m, shielded cable
• Maximum motor cable length 300 m, unshielded cable
• Maximum motor cable cross-sections for performance class:
  • up to 2.2В kW/1.5В mmВІ
  • >В 2.2В kW ≤ 7.5В kW/2.5В mmВІ
  • >В 7.5В kW ≤ 11В kW/4В mmВІ
  • >В 11В kW ≤ 22В kW/10 mmВІ
  • >В 22В kW ≤ 30В kW/16В mmВІ
  • >В 30В kW ≤ 37В kW/25 mmВІ
  • >В 37В kW ≤ 50В kW/35В mmВІ
  • >В 50В kW ≤ 75В kW/70 mmВІ
• Maximum clock frequency 8В kHz
• Maximum motor frequency of output reactor 200В Hz
• Maximum motor frequency of sinewave filter 100В Hz
• UN 3В ACВ 500В V В±5В %.

If these do not meet your requirements, versions in Standard modified or customized solutions are available. For more information contact "mdexx GmbH" in Bremen.
