Patent ID: 8849482

Claim:
A passenger transportation system comprising: at least one rail extending along a path; a trolley movable along the at least one rail; an actuating device including a linear electric motor having: at least one slide fitted to the trolley, and a linear stator extending at least partly along the path, said linear stator including an elongated body and a plurality of power windings embedded in the elongated body, wherein said plurality of power windings generate a first magnetic field by passage of current in said power windings, and said plurality of power windings includes: at least a first coil wound about a first axis in a first winding direction, and a second coil wound about a second axis in a second, opposite winding direction, the first coil and the second coil being connected to each other; and a plurality of sensors fitted to the elongated body and including a control winding associated with the power windings, said control winding located at least partly between the first coil and the second coil to define a region enclosed by the control winding and traversed by the first magnetic field at the first coil and the second coil such that a total magnetic flux of the first magnetic field of the power windings associated with the control winding is nil, said plurality of sensors configured to sense a position of the trolley and transmit at least one signal utilized to control the position of the trolley.
