FIELD: engines and pumps. ^ SUBSTANCE: linear electric motor includes inductor coil (1) with constant magnets (2), which is installed on base (3), housing with armature (4), which is installed on supports (5) with possibility of linear movement along magnetic system of inductor coil (1). Housing with armature (4) is connected to cardboard (6) on which there installed are Hall sensors (7) located in the coverage area of magnetic field of inductor coil (1), end sensors (8) and sensor of zero marker zone (9) in the form of Hall sensors. On end sensors (8) and sensor of zero marker zone (9) there arranged are non-magnetic gaskets (10) on which there arranged are constant magnets of initial installation (11), which have magnetisation vector across active Hall sensor surface (8, 9). On the base, beyond coverage area of inductor coil (1) magnet field there installed are magnets (12) with magnetisation vector opposite to that of magnets of initial installation (11). Magnets (12) are installed so that when the housing with armature (4) is moved, end sensors (8) and sensor of zero marker zone (9), which are installed on cardboard (6), turn out to be located above magnets (12) and interact with the above magnets. ^ EFFECT: enlarging functional capabilities for precision control in zero marker zone and end positions, simplifying the design, increasing interference resistance, reliable operation, and providing more compact arrangement of sensors. ^ 2 cl, 2 dwg |
