Abstract:
A non-contacting torque sensor comprises a magnetic flux generating rotor and a magnetic flux detecting probe. The magnetic flux generating rotor is disposed axially between a first stator and a second stator and has a radially outboard surface and plurality of N pole magnets and S pole magnets alternatingly disposed proximate the radially outboard surface. Each stator has 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 is 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. The N pole magnets and S pole magnets are injection molded.
