Coolblue series cores

COOL BLUE® cores made of NANOPERM® nanocrystalline material are applied for reduction motor-damaging current and voltage emissions in modern high-power inverter systems operating at high switching frequencies.

Current and voltage emissions lead to an early aging and functional loss of motors and generators.

COOL BLUE

COOL BLUE

There are two configurations of filters for motor defense.

COOL BLUE

Among advantages of filters on the base of nanocrystalline COOL BLUE® cores one can note:

  • Low leakage inductance
  • Small size
  • Easy manufacture process, installation and disassembly
  • Low cost
  • Low cost for cooling process

About 3 - 4 cores are required for each electric drive. The cables of the three phases of the electric drive are passed through the COOL BLUE® nanocrystalline cores. Common (zero) wire is displayed separately. The inner diameter of required cores is determined from the diameter of the cable. If it is technically possible, it will be recommended to monitor peak current Ic values ​​before final assembly. If the current exceeds the values ​​in the table, the number of cores should be increased.

In case if a measurement of Ic is impossible, a required quantity and dimensions should be chosen by experimental method. About 3-4 cores are worn on phase cables. If cores temperature is higher the value of 120°С during operating process, the cores quantity should be doubled. If the temperature is still high and exceeds 120°С, it is necessary to choose COOL BLUE® nanocrystalline cores of large sizes.
