SineFormer

With its new SineFormer® EPCOS is introducing a fully new output filter technology for frequency converters. In contrast to conventional filter topologies the new SineFormer simultaneously converts the phase-to-phase voltages into a sinusoidal signal, damps the common mode currents and also forms the conductor-to-ground voltage to sine-shaped voltage.

SineFormer from EPCOS is the cornerstone of the best possible output filter solution – a compact concept that is unique in the market.

Technical arguments

• Increased motor lifetime, reduced noise, bearing currents and eddy current losses
• No forced ventilation, no maintenance necessary
• No feedback to the DC link, meaning reduction of probable radiation sources due to mounting errors

Simpler, easier installation

• Unshielded cables are lighter and more flexible

Logistic benefits

• Unshielded cables are standard products

Economic benefits

• Automatic system cost savings for motor cables ≥ 100 m
