ABSTRACT:
A voice coil linear motor is described in which the armature is supported on a linear bearing attached to the magnet assembly. The magnet assembly comprises a permanent magnet attached to two cup-shaped members which define a gap in which the armature travels. The armature comprises a coil, capacitive position sensing means, and a spindle for a chuck or other device.
