Title:
ANTIFRICTION BEARING EQUIPPED WITH A SENSOR AND ELECTRICAL MOTOR EQUIPPED THEREWITH
Document Type and Number:
WIPO Patent Application WO2004005937
Kind Code:
A3
Abstract:
The invention concerns an instrumented ball-bearing, comprising a rotating part, a non-rotating part, and an assembly for detecting rotation parameters including an encoder (8) and a sensor (7) integral with said non-rotating part and provided with a sensor unit (10), and with at least a microcoil having substantially planar winding, arranged on a support of an integrated circuit arranged in the sensor unit (10) of the non-rotating part such that the microcoil is urged to be axially opposite the encoder (8).
