Sine Wave Filter

Sine Wave Filter

Category:

Features:

The sine wave filter transforms the PWM Output signal of the electro motor into a smooth sine wave of the low residual ripple voltage so as to prevent the damaged to the winding insulation of the motor. It also reduces the occurrence of the distributed capacitance cause by the over-length of cable and the phenomenon of resonances which is resulted from distributed inductance . Besides .It eliminates the over-voltage of the motor caused by high dv/dt, spares the damage of the motor in advance resulted from the eddy-current loss .the sine wave filter also reduces the perceivable noise of the electro motor.

This sine wave filter adopts the foil winding structure and the copper bar leading-out .It is featured with DC resistance . Strong resistance to electromagnetism and excellent overload ability in short time .The usage of F or above grade composite insulating materials with high performance allows for the reliable performance of the equipment under harsh working conditions .Its strong insulating strength makes it possible to bear ultra high voltage shock . The vacuum pressure impregnation process adopted in this sine wave filter reduces the perceivable noise to a low degree.
