Passenger transportation system and relative control method

摘要

A passenger transportation system having at least one rail extending along a path; at least one trolley movable along the rail; an actuating device having a linear electric motor, in turn having at least one slide fitted to the trolley, and a linear stator extending at least partly along the path, and having an elongated body, and a quantity of power windings embedded in the elongated body; and a quantity of sensors configured to control the position of the trolley, the sensors being fitted to the elongated body and so positioned as to minimize noise generated by the power windings on the sensors.

1. 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, anda 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, anda 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.
