V&T EcoDriveCN® sinus filters (sine-wave filters) reduce motor insulation stress and eliminate switching acoustic noise from the motor. Bearing currents are also reduced, especially in larger motors above 50 kW.

Features:

• Reduces voltage peaks in motor;


• Diminishes over voltages and voltage spikes caused by cable reflections;


• It could be paralleled connected, no capacity limited;


• Reduces du/dt stresses;


• Lowers the magnetic interference propagation on surrounding cables and equipment;


• Eliminates acoustic noise in motor;


• Reduces high frequent losses in motor;

The sinus filters output is providing the motor with a nearly ideal voltage signal, thereby increasing motor reliability and extending motor life.

Benefits:

• Prevents flashover in motor windings;


• Protects the motor insulation against premature aging;


• Increases motor service interval;


• Trouble-free operation;


• Noiseless motor operation;


• Prolongs service interval of motor;
