Abstract

The present invention refers to a new electric drive method for linear motor, and, more specifically, an electric drive method essentially based on the sinusoidal pulse width modulation technique, in which electric voltage (31 ) of electric signal comprises at least a wave segment of quadratic spectrum and an electric current (32) of electric signal comprises at least a wave segment of essentially sinusoidal spectrum.
