ANGLE SENSOR, CAPABLE OF ENHANCING THE MEASURING ACCURACY OF AN ANGLE OF A STEERING SHAFT

摘要

PURPOSE: An angle sensor is provided to reduce an error rate of a magnetic element without degradation of the magnetic field transmission detection efficiency and to increase a non-linearity of output data.;CONSTITUTION: An angle sensor comprises a main gear(20), a first sub-gear(22), and a magnetic element. The main gear formed into a ring shape rotates with a steering shaft. The first sub-gear is rotates by a rotation of the main gear and magnets(31,32) are joined in one side. The magnetic element detects a magnetic field change, thereby outputting rotation amount data. The first sub-gear rotates 4 times while the first sub-gear rotates once.;COPYRIGHT KIPO 2012
