Patent ID: 7808133

Claim:
A motor comprising: a magnet assembly having two rows of magnets arranged along a first axis, the two rows of magnets being separated by a gap for generating magnetic flux lines between the rows of magnets; a coil bracket which is located within the gap between the two rows of magnets, the coil bracket further including a first set of coils arranged along the first axis that are operative to drive movement of the coil bracket relative to the magnet assembly along the first axis and a second set of coils arranged along the first axis that are operative to drive movement of the coil bracket relative to the magnet assembly along a second axis which is orthogonal to the first axis, the coil bracket being movable between a first end position and a second end position along the second axis; wherein the first set of coils is configured to be fully located within the flux lines generated by the magnet assembly at both the first and second end positions of the coil bracket and the second set of coils is configured to be located at least partially outside the flux lines generated by the magnet assembly at the second end position of the coil bracket.
