PNG media_image1.png 608 548 media_image1.png Greyscale However Balling et al. teaches the claimed limitation as discussed above except wherein the holding member has a first leg portion, a second leg portion, and a web portion connecting the leg portions, wherein the leg portions for arranging the sensor device on a winding head of the stator device are elastically deformable in such a manner that they radially embrace the winding head and exert a restoring force on the latter. Fippl teaches the claimed limitation as discussed above except wherein the holding member (7) has a first leg portion (8), a second leg portion (8), and a web portion (7a) connecting the leg portions (8), wherein the leg portions (8) for arranging the sensor device (5) on a winding head (2) of the stator device (1) are elastically deformable in such a manner that they radially embrace the winding head (2) and exert a restoring force on the latter as shown in figures 1 ad 2, for the advantageous benefit of providing an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Wu by using the holding member has a first leg portion, a second leg portion, and a web portion connecting the leg portions, wherein the leg portions for arranging the sensor device on a winding head of the stator device are elastically deformable in such a manner that they radially embrace the winding head and exert a restoring force on the latter, as taught by Fippl, to provide an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. As to claim 2/1, Balling et al. in view of Fippl teaches the claimed limitation as discussed above except wherein the leg portions at their ends facing away from the web portion are widened in a direction pointing away from one another. However Fippl teaches the leg portions (8) at their ends facing away from the web portion (7a) are widened in a direction pointing away from one another as shown in figure 2, for the advantageous benefit of providing an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Balling et al. in view of Fippl by using the leg portions at their ends facing away from the web portion are widened in a direction pointing away from one another, as taught by Fippl, to provide an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. As to claim 3/1, Balling et al. teaches wherein the holding member (see annotated figure 3) has a spacer (see annotated figure 3) by which the holding member (see annotated figure 3) is fastened to the bearing shield and which spaces apart the web portion (18) from the bearing shield (43) as shown in figure 3. As to claim 7/1, Balling et al. in view of Fippl teaches the claimed limitation as discussed above except wherein the sensor device has a temperature sensor arranged on the web portion. However Fippl teaches the sensor device (5) has a temperature sensor arranged on the web portion (7a) as shown in figure 2, for the advantageous benefit of providing an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Balling et al. in view of Fippl by using the leg portions at their ends facing away from the web portion are widened in a direction pointing away from one another, as taught by Fippl, to provide an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. As to claim 10/1, Balling et al. teaches wherein the sensor device has a temperature sensor (27) arranged on the first leg portion and/or a temperature sensor (29) arranged on the second leg portion as shown in figure 3. As to claim 13/1, Ballling et al. teaches stator device for an electric machine (see title) , having: a stator (41) which has a winding head (45), and a stator housing (43) having a housing casing and a bearing shield device (see figure 3) fastened to the housing casing (43), and the at least one temperature sensor (27, 29) rests on the winding head (45) as shown in figure 3. However Balling et al. teaches the claimed limitation as discussed above except wherein the leg portions embrace the winding head and exert the restoring force on the latter. Fippl teaches the leg portions (8) embrace the winding head (2) and exert the restoring force on the latter as shown in figure 2, for the advantageous benefit of providing an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Balling et al. in view of Fippl by using the leg portions embrace the winding head and exert the restoring force on the latter, as taught by Fippl, to provide an alternative arrangement with respect to the prior art for contacting a temperature sensor on a winding head of an electric machine, which is effort minimized. As to claim 14/1, Balling et al. teaches for producing a stator device (see figure 3), comprising the following steps: providing a stator (41) which has a winding head (45) and is arranged in a housing casing (43); providing a bearing shield device see figure 3) arranging the bearing shield device (see figure 3) on the housing casing (43) and the temperature sensor (27, 29) rests on the winding head (45); and fastening the bearing shield device to the housing casing (43) as shown in figure 3.
