Abstract
A polyphase linear induction motor including a movable primary member (100), the primary member (100) including a magnetic material (110), a polyphase winding (120) arranged around the magnetic material, and a stationary longitudinally-extending secondary member (150) separated from the primary member (100) by a gap, the secondary member (150) including an electrically-conductive reaction plate (200) and a backing magnetic material (300), wherein the secondary member includes a middle section (205) and two outer sections (210.1, 210.2), the middle section (205) and the two outer sections (210.1, 210.2) arranged next to each other in parallel to an axis of longitudinal extension of the reaction plate (200).

A polyphase linear induction motor comprising:
- a movable primary member (100), the primary member (100) including a magnetic material (110), a polyphase winding (120) arranged around the magnetic material;
- and
- a stationary longitudinally-extending secondary member (150) separated from the primary member (100) by a controlled gap, the secondary member (150) including an electrically-conductive reaction plate (200) and a backing magnetic material (300),
- wherein the electrically-conductive reaction plate (200) includes a middle section (205) and two outer sections (210.1, 210.2) having an increased electric conductivity as compared to an electric conductivity of the middle section (205) wherein at least one winding of the polyphase winding (120) of the movable primary member (100) includes windings arranged to support the operation of the primary member in a trapezoidal shape;
- and
- wherein an angle of inclination between the outer sections (210.1, 210.2) and the middle section (205) is different at a first section and a second section along the axis of longitudinal extension of the reaction plate (200), the first section being located at a different location than the second section.
A polyphase linear induction motor comprising:
