Line Reactors and Output Filter In applications with a
variable frequency drive or servo-motor, the need arises to reduce
harmonic distortion on the power line side and the over-voltages
generated on the output side, which are potentially harmful to motors.
For this reason, Enerdoor has created several series of line and load
inductances with common-mode and differential mode applications. These
series are able to reduce harmonic distortion and protect the motor.
To
reduce the PWM effect, Enerdoor offers the sinus wave filter series,
which converts the PWM into a sine wave and reduces the dV/dt. The sine
wave FIN915SF series is used with fundamental frequencies up to 2 kHz.
The
high frequency inductance FIN960F is a specific product used for
synchronous motor spindles. Various combinations of current and
inductance values are available. Custom inductances are available upon
request.
