Description
Three-phase motor choke 15A, 380V, 5.5 kW, 0.94 mH OCL-0015-0M47-0.4SC is installed at the output of a frequency converter to filter the current supplied to three-phase electric motors 380 V. The purpose of the output choke coil is as follows:
- Creating inductive resistance that limits the motor supply current, thus preventing overload and damage;
- Preventing sharp current spikes during motor startup that may fail equipment;
- Cleaning the current sine wave from unwanted high harmonics (high-frequency noises) that occur in the drive.
Use the AC output choke in the circuit between the converter and the asynchronous electric motor to improve the quality of power supply to the drive and ensure safe and long-term operation of the equipment.
