Abstract
A novel groove shape of a generator stator. The generator stator silicon steel sheet comprises a generator stator silicon steel sheet 1, wherein the generator stator silicon steel sheet is provided with an inner groove 2, the shape of the inner groove is that a top end arc line is parallel to an outer arc of the stator silicon steel sheet, and a winding coil wire is arranged in the inner groove. The utility model is used for two kinds of generators of single-phase or three-phase excitation and permanent magnetism.
Description
The technical field is as follows:
the utility model relates to a novel flute profile of generator stator.
Background art:
when the generator continuously operates for a long time, the surface temperature of the generator body can generate heat, thereby causing energy waste. In order to find the reason of the temperature rise of the generator, a large amount of analysis and optimization are carried out on the structure of the generator stator silicon steel sheet, and the reason of the generator fever is finally found: the stator induction magnetic field is not uniformly distributed, so that the heating phenomenon is generated, and the energy waste is caused.
The invention content is as follows:
the utility model aims at providing a novel flute profile of generator stator that original generator can save energy by more than 3%.
The above purpose is realized by the following technical scheme:
the novel groove shape of the generator stator comprises a generator stator silicon steel sheet, wherein the generator stator silicon steel sheet is provided with an inner groove, the inner groove is in a shape that a top end arc line is parallel to an outer arc of the stator silicon steel sheet, and a winding coil wire is arranged in the inner groove.
The novel groove shape of the generator stator is characterized in that the conducting wires on the outer edge of the winding coil are equidistant from the shell.
The novel groove shape of the generator stator, the groove comprises an opening, the opening is distributed around the circumference, the opening is connected with a left arc groove line, the left arc groove line is connected with a left groove line, the opening is connected with a right arc groove line, the right arc groove line is connected with a right groove line, the left groove line is connected with the right groove line through an arc flat line, and a group of excircle positioning grooves are formed in the excircle of the generator stator silicon steel sheet around the circumference.
The novel groove shape of the generator stator is characterized in that the outer circle positioning groove and the inner groove are arranged in a staggered mode.
Has the advantages that:
1. the utility model has the advantages that through the application of the shape of the stator silicon steel sheet and the rearrangement of the winding, the induction magnetic field of the generator stator is uniform on the premise of not increasing the cost; the temperature of the machine body can be reduced by 5-8 ℃; the full slot rate of the generator winding can be improved; compared with the original generator, the energy is saved by more than 3%.
2. The utility model discloses can be used for single-phase or three-phase excitation and two kinds of generators of permanent magnetism, application scope is wide.
3. The utility model discloses the flute profile can make the full flute rate of stator winding high, and the generator generated energy increases to some extent under the same condition.
Description of the drawings:
fig. 1 is a schematic structural diagram of the product.
Fig. 2 is a schematic structural diagram of a generator stator silicon steel sheet in the prior art.
The specific implementation mode is as follows:
the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.
Example 1:
a novel groove shape of a generator stator comprises a generator stator silicon steel sheet 1, wherein the generator stator silicon steel sheet is provided with an inner groove 2, the inner groove is in a shape that a top end arc line is parallel to an outer arc of the stator silicon steel sheet, and a winding coil wire is arranged in the inner groove.
And the conducting wires at the outer edge of the winding coil are equidistant from the shell.
Example 2:
embodiment 1 a novel flute profile of generator stator, the groove include opening 3, the opening distribute around the circumference, the opening connect left arc slotline 4, left arc slotline connect left slotline 5, the opening connect right arc slotline 6, right arc slotline connect right slotline 7, left slotline with right slotline between connect through arc flat line 8, the excircle of generator stator silicon steel sheet open around the circumference and have a set of excircle constant head tank 9.
The excircle positioning groove and the inner groove are arranged in a staggered mode.
Example 3:
according to the novel groove shape of the generator stator, the groove-shaped top end of the silicon steel sheet of the conventional generator stator is generally in a circular or oval shape 10, so that the shape of the groove body enables the top end of a winding coil to be closer to a motor shell, and the generator shell and the stator are easy to generate heat under an alternating induction magnetic field, thereby causing energy waste; the generator stator silicon steel sheet groove-shaped top end arc line and the edge line of the stator excircle are in parallel shapes, the defects are well overcome, and the following good effects can be produced:
the top arc of the slot shape of the generator stator silicon steel sheet is parallel to the edge line of the excircle of the stator, so the slot shape can lead the top end of the winding coil to be far away from the shell of the motor, and the coil conducting wire is equidistant from the shell.
