Electrical window raiser contains the electrical motor connected with the holder of glass and the rack, electrical motor executed in the form of nonreversible piezoelectric engine, rotor and stator of which is frictionally connected together with the help of elastic plates - pushers. Rotor is motionlessly connected with the stator of similar piezoelectric engine with opposite direction of rotation, rotor of which with the help of the gear is connected with the rack. Piezoelectric engines are connected to the control unit, which connects one piezoelectric engine at lifting, and other - during lowering of glass. Furthermore, the control unit is connected to the position detector of glass.
