Reduce the motor insulation stress and bearing currents.
VLT® Sine-wave Filter MCC 101 output filters are low-pass filters that suppress the switching frequency component from the drive and smooth out the phase-to-phase output voltage of the drive to become sinusoidal.
Overview
VLT® Sine-wave Filter MCC 101 output filters are differential-mode low-pass filters that suppress the switching frequency component from the drive and smooth out the phase-to-phase output voltage of the drive to become sinusoidal. This reduces the motor insulation stress and bearing currents.
By supplying the motor with a sinusoidal voltage waveform, the switching acoustic noise from the motor is also eliminated.
Features & Benefits
• Supplies the motor with a sinusoidal voltage waveform
• Eliminates over-voltages and voltage spikes caused by cable reflections
• Reduces electromagnetic interference by eliminating pulse reflection caused by current ringing in the motor cable. This allows the use of unshielded motor cables in some applications
• Eliminates acoustic noise in motor
• Reduces high frequent losses in motor
