Abstract:
1. A non-contacting torque sensor comprising: a magnetic flux generating rotor disposed axially between a first stator and a second stator; and a magnetic flux detecting probe; the magnetic flux generating rotor having a radially outboard surface and plurality of N pole magnets and S pole magnets alternatingly disposed proximate the radially outboard surface; each stator having a plurality of stator teeth, with each one of said plurality of stator teeth corresponding to a unique one of said plurality of N pole magnets and S pole magnets; the magnetic flux detecting probe disposed at a distance from the radially outboard surface and configured for detecting variations in magnetic flux produced by the magnetic flux generating rotor to detect a change of a relative twist between the magnetic flux generating rotor and the first stator and second stator; wherein the plurality of N pole magnets and S pole magnets is injection molded.
