An Electrical Linear Motor having a number of electrical windings with long linear sections arranged parallel to the linear path of the motor. A row of equidistant magnets parallel to the linear path and having alternating magnetic field direction perpendicular to the linear path of the motor is provided. A number of magnetic circuits each enclose some of the long linear winding sections, further referred as “set of long linear sections”. Any two of these magnetic circuits enclose a different set of long linear sections. Each magnetic circuit is provided with an opening receiving the magnet row. The magnet row and the magnetic circuits slide along the linear path relatively to each other to vary working force. A required force value is obtained by controlling the current in the windings for each position of the moving row relative to the magnetic circuits.
