Field of the Invention This invention relates to an AC motor stator, particularly to one provided with a plurality of wire grooves and magnetomotive forces generated by wires of a coil wound around each section between every two neighboring wire grooves of the stator are continuative to one another, so the power of the motor may be upgraded. 2. Description of the Prior Art A conventional AC motor stator 30 shown in Figs. 1, 2 and 3 is made of plural thin silicon steel plates 31 laminated, and the thin silicon steel plates 31 are respectively provided with a center hole 32 for receiving a rotor 40 therein, and a plurality of wire grooves 33 are axially formed spaced apart equidistantly around the wall defining the center hole 32, and wires of a coil are wound around each section between two every neighboring wire grooves 33. having respectively an opening 330 communicating with the center hole 3 2. When the coil is electrified, the wires of the coil wound around each section between every two neighboring wire grooves 33 may generate magnetomotive force to force the rotor 40 to rotate. As the wire grooves 33 of the conventional AC motor stator 30 are formed axial, so the magnetomotive force generated by each section between every two neighboring wire grooves 33 is feeble, causing the whole magnetomotive force not distributed evenly and not continuative, so the power of the motor is affected.

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an AC motor stator,
particularly to one provided with a plurality of wire
grooves and magnetomotive forces generated by wires of
a coil wound around each section between every two
neighboring wire grooves of the stator are continuative
to one another, so the power of the motor may be
upgraded.
2. Description of the Prior Art
A conventional AC motor stator 30 shown in Figs.
1, 2 and 3 is made of plural thin silicon steel plates 31
laminated, and the thin silicon steel plates 31 are
respectively provided with a center hole 32 for receiving
a rotor 40 therein, and a plurality of wire grooves 33 are
axially formed spaced apart equidistantly around the
wall defining the center hole 32, and wires of a coil are
wound around each section between two every
neighboring wire grooves 33. having respectively an
opening 330 communicating with the center hole 3 2.
When the coil is electrified, the wires of the coil wound
around each section between every two neighboring wire
grooves 33 may generate magnetomotive force to force
the rotor 40 to rotate. As the wire grooves 33 of the
conventional AC motor stator 30 are formed axial, so the

magnetomotive force generated by each section between
every two neighboring wire grooves 33 is feeble, causing
the whole magnetomotive force not distributed evenly
and not continuative, so the power of the motor is
affected.
SUMMARY OF THE INVENTION
This invention has been devised to offer an AC
motor stator generating the magnetomotive force evenly
distributed and each magnetomotive force generated by
each section of wires of the coil in each wire groove
continues with one another to boost the power of the
motor.
The feature of the AC motor stator in the invention
is wire grooves of the stator are formed to incline for a
certain angle to the outer surface of the stator in the
same direction, enabling the magnetomotive force
generated by the wires of the coil in each section evenly
distributed and continue to one another,

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT
A preferred embodiment of an AC motor stator in
the present invention, as shown in Figs. 4, 5, 6 and 7,
includes a plurality of thin silicon steel plates 11

respectively provided with a center hole 12 for receiving
a rotor 20 therein, and a plurality of wire grooves 13
spaced apart equidist antly around the wall defining the
center hole 12 for each part of wires of a coil to be
received therein. Each wire groove 13 has a narrow
opening 130 communicating with the center hole 1.
The wires grooves 13 of the stator 10 are formed
inclined in a certain angle to the surface of the stator 10,
and positioned in parallel with one another. So when the
coil is electrified, the magnetomotive forces generated
by the sections between every each two neighboring wire
grooves 13 are continuative with one another to boost

the power of the motor. Further, the openings 130 of the wire grooves 13 are
also formed to incline as are the wire grooves 13 themselves, and the inclined
direction of the wire grooves 13 of the stator is made to be opposite to that of
the grooves 21 of a rotor 20, which are formed also inclined for an angle and
also parallel to one another, as shown in figs. 4 and 7.
It is quite important that the wire grooves 13 of the stator of an AC
motor are formed not straight but inclined at an angle to the surface of the
stator, so the sections between every two neighbouring wire grooves 13 may
have the magnetomoving force generated as continuative to each other so as to
upgrade the power of the AC motor and permitting the rotor 20 to rotate
smoothly.
Thus according to the present invention there is provided An AC motor
stator comprising a plurality of thin laminated silicon steel plates, said silicon
steel plates having a center hole for receiving a rotor therein and a plurality of
wire grooves spaced apart equidistantly around the wall defining the said center
hole, each formed wire groove having a narrow opening communicating with
the said center hole, said wire grooves are inclined at an angle to an outer
surface of said stator and is parallel to one another and the said rotor having a
plurality of grooves spaced apart equidistantly around the outer circular
circumference, and the said grooves are inclined at an angle to the outer surface
of said rotor, and the inclined direction of said grooves of said rotor is opposite
to that of said stator.
Further according to the present invention, openings of the wire grooves
of the stator are also inclined as the wire grooves are.

made therein and the appended claims are intended to cover all such
modifications that may fall within the spirit and scope of the invention.

communicating with the said center hole, said wire grooves are
inclined at an angle to an outer surface of said stator and is
parallel to one another and the said rotor having a plurality of
grooves spaced apart equidistantly around the outer circular
circumference, and the said grooves are inclined at an angle to
the outer surface of said rotor, and the inclined direction of said
grooves of said rotor is opposite to that of said stator.
2. The AC motor stator as claimed in claim 1, wherein said
openings of said wire grooves of said stator are also inclined as
said wire grooves are.
