Description
Technical Field
The utility model relates to the technical field of electric machines, specifically a single double-deck accurate sinusoidal winding structure of concentric type.
Background
The sine of the motor stator winding is one direction pursued by a motor designer, and the sine winding can greatly reduce the harmonic content, so that the harmonic loss is reduced, and the sine winding motor is very beneficial to improving the motor efficiency and reducing the vibration and noise of the motor. At present, energy conservation and emission reduction are advocated in China, high-efficiency energy-saving motors are widely popularized, and the motor industry strives to apply sinusoidal windings to the design and production of ultrahigh-efficiency motors so as to achieve the purposes of improving the motor efficiency and reducing the vibration and noise of the motors.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model aims at providing a single double-deck accurate sinusoidal winding structure of concentric type, the distribution value of each coil turn when changing the coil coiling just can realize the accurate sinusoidal distribution of every utmost point every looks turn number behind the winding rule.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a single double-deck concentric formula quasi-sinusoidal winding structure, when with every utmost point every phase slot number q =4, the half phase belt number of turns is adjusted during the wire winding, and the ratio distributes according to 1.
Through the setting, the utility model discloses a novel motor of producing not only can reduce motor vibrations and noise, can also improve the efficiency index of motor, and this kind of single double-deck concentric type accurate sinusoidal winding has very good application prospect among the design and the production of energy-efficient motor.
Drawings
The present invention will now be further described with reference to the accompanying drawings.
Fig. 1 is a schematic winding diagram of a stator winding according to the present invention;
fig. 2 is a schematic diagram of the stator winding inserting line of the present invention.
In the figure: the ratio of the number of conductors in each phase slot of each pole is 1.
Detailed Description
As shown in fig. 1 and fig. 2, a single-double layer concentric quasi-sinusoidal winding structure, when the number of slots per pole per phase q =4, illustrates the winding and winding principle of this novel winding through the attached drawings of the specification, and it can be seen from the schematic diagram that, when winding, the number of turns of a half-phase band is adjusted (i.e. coil No. 1, coil No. 2, coil No. 3 in fig. 2), the ratio is distributed according to 1.
The utility model has the characteristics of it is following:
1. when the stator coil is wound, the half-phase belt turn number distribution ratio is distributed according to the following steps of 1;
2. the distribution rule of the number of turns per pole per phase after wire insertion is 1.
The above description is only illustrative of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
