<p>In an electric linear motor the stator coils are arranged in a line, and the field they produce advances along that line driving the translator along with it. None of the known linear motors can provide all of very high speed, low force, long travel, high linearity and very low moving mass; the present invention proposes an answer in the form of a mechanism that applies motive, displacing force not primarily in the direction along with translator movement is desired but instead approximately at right angles to that direction, the translator being "squeezed" out like a cherry pip squeezed between finger and thumb. The invention suggest a linear motor comprising a linearly-extensive stator (1) supporting a translator (2), the stator providing in operation a squeezing force across the translator in a direction approximately orthogonal to the line of stator, and the translator either having along its movement direction a slightly tapered profile or being mounted on the stator by force-transmitting bearings (3) that when so squeezed deform to become slightly tapered, the effect being to produce a resultant force on the translator that is along the line of the stator. <IMAGE> <IMAGE></p> |
