DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Objections
Claims 1 and 10 are objected to because of the following informalities:
Claim 1 is objected to, as the claim ends with the word “and”, making the claim incomplete. Appropriate corrections are required; and
in claim 10, please remove the period in the middle of the claim (the period appears right before the limitation stating “the stator core is sleeved on the rotor...”).
Appropriate correction is required.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 7 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Saint-Michel et al. as applied to claims 1 and 10 above, and further in view of Shiah (US Patent Application Pub. No.: US 2004/0020027 A1).
For claim 7, Saint-Michel et al. disclose the claimed invention except for each group of second silicon steel sheets comprising one or more second silicon steel sheets, and the one or more second silicon steel sheets in each group of second silicon steel sheets being connected end to end to form a ring-shaped structure.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the one or more second silicon steel sheets forming a ring-shaped structure as disclosed by Shiah for the second silicon steel sheets of Saint-Michel et al. for predictably providing desirable configuration for facilitating the assembly of the device.
For claim 16, Saint-Michel et al. disclose the claimed invention except for each group of second silicon steel sheets comprising one or more second silicon steel sheets connected end to end to form a ring-shaped structure. Shiah discloses one or more second silicon steel sheets (reference numeral 58, see figures 10, 11) connected end to end to form a ring-shaped structure (see figures 10, 11), and it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the one or more second silicon steel sheets connected end to end to form a ring-shaped structure as disclosed by Shiah for the second silicon steel sheets of Saint-Michel et al. for predictably providing desirable configuration for facilitating the assembly of the device.
Claim(s) 8 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Saint-Michel et al. as applied to claims 1 and 10 above, and further in view of Kamo (Japanese Patent Document No.: JP 2011125176 A).
For claim 8, Saint-Michel et al. disclose the claimed invention except for a material of the first silicon steel sheet being different from a material of the second silicon steel sheet; or the material of the second silicon steel sheet being non-oriented silicon steel, the material of the first silicon steel sheet being oriented silicon steel, and an orientation of the oriented silicon steel being parallel to the radial direction of the stator core.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the non-oriented silicon steel for the second silicon steel sheet and to have the oriented silicon steel for the first silicon steel sheet as disclosed by Kamo for the first and second silicon steel sheets of Saint-Michel et al. for predictably providing desirable configuration for facilitating the assembly of the device.
For claim 17, Saint-Michel et al. disclose the claimed invention except for at least one of: a material of the first silicon steel sheet being different from a material of the second silicon steel sheet; the material of the second silicon steel sheet being non-oriented silicon steel, the material of the first silicon steel sheet being oriented silicon steel, and an orientation of the oriented silicon steel being parallel to the radial direction of the stator core.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the non-oriented silicon steel for the second silicon steel sheet and to have the oriented silicon steel for the first silicon steel sheet as disclosed by Kamo for the first and second silicon steel sheets of Saint-Michel et al. for predictably providing desirable configuration for facilitating the assembly of the device.
Claim(s) 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Saint-Michel et al. as applied to claim 19 above, and further in view of Xia et al. (Foreign Patent Document No.: CN 114142635 A).
For claim 20, Saint-Michel et al. disclose the claimed invention except for mounting the stator winding into the stator slot from the outer side of the plurality of groups of the first silicon steel sheets further comprising: pre-winding the stator winding into a centralized winding; and then mounting the centralized winding into the stator slot from the outer side of the plurality of groups of first silicon steel sheets; or forming the stator winding into a continuous wave winding; and then mounting the continuous wave winding into the stator slot from the outer side of the plurality of groups of first silicon steel sheets. Xia et al. disclose forming the stator winding into a continuous wave winding (see translation of Xia et al., third page, third paragraph under “Disclosure of Invention”); and then mounting the continuous wave winding into the stator slot from the outer side of the plurality of groups of first silicon steel sheets (i.e. translation of Xia et al. discloses the continuous wave winding being mounted from an outer side of the winding groove, see translation of Xia et al., third page, third paragraph under “Disclosure of Invention”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the continuous wave winding mounted onto the silicon steel sheets as disclosed by Xia et al. for the stator winding of Saint-Michel et al. for predictably providing desirable configuration for facilitating the assembly of the device.
