Patent abstract
A sensor includes a stator having four or more magnetic pole teeth and concentric with a stationary-side raceway member, and excitation coils and detection coils wound around the respective magnetic pole teeth. Signals generated in the detection coils according to distances between the magnetic pole teeth and a rotation-side raceway member are taken out for the respective magnetic pole teeth. The load acting on a rolling bearing is obtained in processing means from these signals.
