ROTATION ANGLE SENSOR |
摘要 |
To make it possible for a rotation angle sensor to be manufactured and assembled more easily and more accurately, the part components of a stator element (21) made of a ferritic material are held in a sintered stator body, made by a sintering technique, by at least one holding element in a holding recess of a base element made of a non-magnetizable material. A magnetic holding device (26, 27) is a holding element made by a metal injection moulding (MIM) technique with an at least partly formed magnetic isolation zone and at least one recess. An annular magnetic element (24) is attached inside the MIM holding device by means of at least one slit-shaped recess and at least one compatible linking element, and positioned at a given angle ( alpha ) in relation to a gap, between the sintered stator bodies. |
