Title:
ELECTRIC DRIVE METHOD FOR LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2013/188940
Kind Code:
A3
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.
