Abstract
The linear motor conveyance system is intended to power conveyance in shafts, typically mine shafts. The system includes spaced apart, parallel winding support members 10 carrying stator windings and extending in the direction of the shaft. A reaction member 16 is located between the winding support members 10 so as to be driven along the shaft by electromagnetic forces. The reaction member 16 is composed of a number of reaction elements, typically permanent magnets 18, which are arranged in groups 20. The groups are articulated to one another to take account of shaft inaccuracies.
