<p>The mine shaft conveyance system makes use of a synchronous linear motor to drive mine conveyances up and down a shaft. The system includes spaced parallel winding support members which carry stator windings and between which a reaction member is located so as to be driven in the required direction by electromagnetic forces when current is supplied to the windings. The reaction member is flexible about at least one axis transverse to the length of the winding members.</p> |
