product overview:
Installed at the output end of the frequency converter, it is used to limit the capacitive charging current of the cable connecting the frequency converter and the motor. The PWM wave filtering and shaping output by the frequency converter improves efficiency. When the length of the motor cable exceeds a certain value, it is recommended to connect a reactor between the frequency converter and the motor. Used to compensate for the recharging current of capacitors in long wires. The maximum length depends on the rated value of the frequency converter and the type of motor cable.
Recommended for use in the following situations:
1. Limit dv/dt to 500V/us.
2. Limit the overvoltage on the motor terminals to 1000V to 400V~(rms value) and 1150V to 460V~(rms value).
3. Suppress high-frequency interference from the frequency converter.
4. Reduce the ground leakage current of the motor.
