Sine-wave filters

Function

Pulse Width Modulation is a great method to control electric motor operation, but has negative impact on its lifespan. EF3LC filter converts rectangular PWM voltage into sinusoidal thus eliminates harmful side effects of transistors switching. Application of LC filter on inverter output will protect motor against high voltage peaks, bearing currents, overheating and cable ringing, which cause premature insulation and armature damage. Due to compact design, filter can be easily integrated with existing system and is ready to use right after installation.

Benefits	Application
Prolonged motor lifetime Extended motor cable length Cheaper, unshielded cables can be used Reduction of service costs Lower motor noise	Motors with PWM drives Submersible pumps Drives with long cable routes Motors in explosive atmospheres High power drives for critical applications Mining & Minerals Oil & Gas Chemical industry
