Preferably, rotary angle transmitter has by metal or at least by being covered with the rotationally symmetric body that metallic surface is made, thus the side face of rotary angle transmitter is suitable as the sliding surface for sliding contact element。
Particularly advantageously, the sliding contact element of electric potential balancing device is placed in brush carrier as the additional brush supported movably。Sliding contact element thus can construct in the same manner as other brushes and be bearing in brush carrier, from without the component ad hoc constructed especially to realize sliding contact element。
The especially compact structure form with the brush carrier of the sliding contact element of insertion is obtained by the brush being arranged in line。
In the simplest situations, for the sliding surface of the conduction of the sliding contact element of electric potential balancing device can be the cylindrical side face of housing of rotary angle transmitter。
If rotary angle transmitter is connected with armature spindle coaxially by connecting axle, then connect the sliding surface that the side face of axle also can be directly used as the conduction of sliding contact element for electric potential balancing device。This is accomplished by connecting the contact area that axle place little can be freely close, in order to sliding contact element can be contained in the side face place connecting axle。
Connect axle and there is relatively small diameter, thus its side face and thus corresponding sliding surface have peripheral speed little accordingly when armature spindle rotates。Thus, it is kept as only small accordingly at sliding contact element place and the same abrasion at sliding surface place。
Version according to the rotary angle transmitter used, the sliding surface at rotary angle transmitter place also can relative to the axial direction of armature spindle orientation deviously。Now, sliding contact element has the contact surface of respective orientation。At this, the brush forming sliding contact element can vertically highlight from sliding surface, to obtain the optimum contact between sliding surface and brush。
Sliding surface can be formed by coating, and this coating has only small coefficient of friction relative to the contact surface abutting in this coating place of brush。Thus, significantly reduce corresponding brush place and abrasion at sliding surface place。
Sliding surface at rotary angle transmitter place also can be formed by slip ring, and slip ring is arranged on rotary angle transmitter place, for instance be arranged on its housing or it connects axle place。Thus, exactly, even if when the case material of rotary angle transmitter does not have the contact performance of optimum, it is possible to realize providing the sliding surface of contact and the sliding capability with optimum。
The sliding surface arranged for sliding contact element can be very advantageously made up of copper alloy。Combining with the traditional brush as sliding contact element, copper alloy has extraordinary contact and sliding capability。
In any case sliding contact element is not only obtaining extremely joint space-efficient electric potential balancing device as brush for the arrangement in the brush carrier required for rotor windings energising, and also achieves and directly electrically connected with the earth potential of motor by the contact element prominent at brush carrier place。Thus, in order to the grounding connection being based upon between armature spindle and ground does not need wiring measures, thus the assembly cost need not added for the contact of electric potential balancing device。
