EP comments

JP thanks the WG for examining the Proposal. For each issue mentioned in the
WG Decision for which comments are invited, JP comments are presented
below.
(1) whether the references to H02K 1/00 and H02K 3/00 in subclass H02K
are really limiting:
JP, taking into consideration of the WG Decision, shall delete description of
references pointing to H02K 1/00 and H02K 3/00. Because H02K 1/ and H02K
3/ are major categories in H02K, if they are not limiting references, keeping them
as informative references is unnecessary.
H02K11/00
Structural association of dynamo-electric machines with electric
components or with devices for shielding, monitoring or protection
(casings, enclosures or supports H02K 5/00 )
(2) to assess the proposal by Germany in Annex 2 in relation to group
H02K 11/044:
Considering the ANNEX 2, JP proposes to reorganize H02K 11/044-048 into
following groups from the aspect of arrangement of rectifier.
Based on the EP comment, hierarchy of 11/044 and 11/046 as per the ANNEX
19 shall remain the same. As for H02K 11/048, JP proposes to upgrade the
hierarchy by one-dot and change the aspect as follows. In other words, its
aspect should be unified with H02K 11/042 to arrangement.
H02K11/044 ・・arrengement of magnetic circuit with stator
H02K11/046 ・・arrengement of windings with stator
H02K11/048 ・・arrengement of casings, enclosures or supports with stator
H02K11/33
・・Drive circuits, e.g. power electronics
(H02K 11/38 take precedence)
(3) whether the references to H02K 29/06 and H02K 29/14 in group H02K
11/21 are really limiting:
These references are limiting references.
For the purpose of facilitating search activities, JP deemed it better to
concentrate non-mechanical commutating devices into H02K29.
(4) whether the “using machine windings as detecting coil, i.e., sensorless
position control” in group H02K 11/225 fits in this main group:
JP is of the opinion that sensorless position control per se is not covered by this
main group.
Instead, “control” aspect should be covered by H02P.
Also, if it is sensorless, then there is no coil devoted exclusively for detection.
Thus, it shall not be provided for by H02K11.
JP proposes to delete the “e.g. and subsequent phrase” from the H02K 11/225
title.
H02K11/225
・・・Detecting coils
(5) whether the approved titles of groups H02K 11/24 to H02K 11/27 reflect
the intended scope:
As JP sees it, the intended scope is “sensing or actuated thereby”.
The term “responsive” is inadequate because its scope is unclear.
Therefore, JP proposes to use expressions which GB proposed in the ANNEX
15. This goes the same for H02K11/21.
What measures torque by detecting current should be classified in H02K11/27.
Therefore, a precedence reference pointing to H02K11/27 should be added in
H02K11/24.
H02K11/21
H02K11/24
H02K11/25
H02K11/26
H02K11/27
・・ Devices for sensing speed or position, or actuated thereby
(specially adapted for machines having non-mechanical
commutating devices H02K 29/06, H02K 29/14)
・・Devices for sensing torque, or actuated thereby
(H02K 11/27 takes precedence)
・・Devices for sensing temperature, or actuated thereby
・・Devices for sensing voltage, or actuated thereby
e.g. over-voltage protection devices
・・Devices for sensing current, or actuated thereby
(overcurrent protection relate to temperature H02K 11/25)
(6) the role of “gear motors” in group H02K 11/38 with respect to the drive
circuits covered by the head group:
According to EP, gear motors refer to special combination of gear box and
motor.
Only that mere structural association of electric motor and gear box is classified
in H02K7/116.
H02K11/3, then, must cover structural association of gear box and drive circuit
or control circuit.
Therefore, the informative reference should be included in H02K11/38.
(7) Concerning to EP comments:
As per of H02K, H02K11 is not required to describe limiting references to
H02K16/00-99/00.
But it does preclude H02K11 from carrying informative references in the
definition.
Therefore, the informative references shall be added in H02K11/00.
