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 below are objected to because of the following informalities:
Claim 2 recites “a length of the multiple passing slots is defined among the two flanges and the peripheral fence”. Examiner suggests “between” for clarity.
Appropriate correction is required.
Specification
The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed.
The following title is suggested: Cooling structure of rotator for axial flux motor.
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 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.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lin et al (EP4325694A1), hereinafter Lin.
Regarding Claim 1, Lin discloses (Figs 2a,4, 5a, 6) a rotator (30) for an axial flux motor (100)[Background] comprising: a core (31,33) and two permanent magnets (332 on both opposing sides) located on two end surfaces (Fig 6 axially opposite sides) of the core;
wherein the core (31 including 334) includes two circular grooves (Fig 5a, 310) defined on the two end surfaces (Fig 5a) of the core, two flanges (Fl) formed on two centers (Fig 5a) of the two end surfaces of the core, and a peripheral fence (314) formed on an outer wall (314) of the core, multiple passing slots (318) [Para 0048 discloses “In another implementation of this application, a quantity of cooling channels 318 is not limited. The cooling channel 318 is provided with a plurality of interconnected sub-channels. The sub-channels may be provided on the inner ring 312, the outer ring 314, and the rib 316”] radially formed on the two end surfaces of the core, and multiple through orifices (318) defined around the peripheral fence (314) and communicated with the multiple passing slots [0048]; and
wherein a respective one permanent magnet of the two permanent magnets is circular (Fig 6) and includes multiple N poles and multiple S poles, wherein the two permanent magnets are fitted in the two circular grooves (310) of the core and are magnetically attracted (334 and 332) on the core.
