Sorry, missed your follow up. Just changed my newsreader characteristics and it surfaced. Look at:-
Globalspec Engineering search Engine Show all Linear Motors companies Quote <Linear motors generate force only in the direction of travel. A linear motor applies thrust directly to a load, and does not require any intermediate mechanism to convert rotary motion into linear motion. Linear motors are capable of extremely high speeds, quick acceleration, and accurate positioning.
Choices for linear motors include moving coil, moving magnet, AC switched reluctance design, AC synchronous design, AC induction or traction design, linear stepping design, DC brushed design, and DC brushless design.........> Unquote

I think Keith's point was that linear motors can be brushless but this doesn't mean all brushless motors are linear.
