KEB Sine filters provide a perfect sinusoid waveform to the motor. This reduces motor heating and is advantageous for installations where the drive and motor are separated by extreme distances.

Sine Wave Filters
Product Details
KEB Sine Filters are low-pass filters that filter out the switching frequency from the pulse width modulation (PWM) from the output of an inverter. The filter then provides a sinusoidal motor current.
When a KEB Sine Filter is used, the allowable motor cable length can be up to 500 meters. The sinusoidal output voltages reduce discharge currents driven by pulse frequency.
The sinusoidal voltage between phases reduces motor noise.
Customers can also expect to see a reduction in high-frequency transient emissions and improve the entire EMC load on the equipment.
