Sinus filters are used to filter out the high frequency componnets of the PWM generated voltage waveshape at the output of motor drives. They are especially useful for applications where data cables are installed close to pwoer cables of a drive. By filtering out high frequency components, they prevent electromagnetic interference from causing unwanted signals to occur in the system. Moreover, a sinusoidal shaped voltage at the terminals will increase lifetime expectancy of motors.

Additionaly, motor drives with a sinus filter can be used to supply different types of loads than motors.
By installing a sinus filter to a system, ringing effects due to long cable lengths will also be prevented. Sinus filters can be used for a variety of applications, not limited to motor drives only.
