Abstract:
A surgical tool with an electric motor. The motor rotor includes a bore in which a number of magnets are disposed. Each magnet has an outer surface and two inner surfaces that extend inwardly towards a corner. One pole of each magnet is along the outer surface; the opposed pole is at the corner. The magnets are disposed in the rotor bore so that the corners of arcuately adjacent magnets have opposed magnetic polarities.
