| 简介 |
The invention relates to a magnetic rotary encoder and a method of manufacturing the same, which indicates the angular position secured on a rotating shaft a rotation angle sensor or the rotation of the shaft. Such rotary encoder are made of a magnetic material usually, based on rare earth alloys different, . Rare earth alloys different raw materials are relatively expensive and the available limited, rotary encoder from other fields for the sensors used so far to small but generate [...] materials. The invention describes a rotary encoder, the runs is made of an anisotropic hard ferrites, and from one half to the other half of the preferred direction in which an arcuate end face pointing to the sensor. Furthermore, the invention describes a method for producing such an in the resolver injection moulding process, wherein the preferred direction in the rotary encoder either by magnets or by a current conductor mounted in the injection moulding die is caused or a leader crowd. The according to the invention can be manufactured more cost-effective due to its configuration and the method described rotary encoder as the previous rotary encoder. |
