Description
Technical field
The utility model relates to technical field of generators, specially a kind of rotor structure for generator.
Background technique
Generator is that electromotive force, the device to convert mechanical energy to electric energy are generated by electromagnetic induction, generator output
The size of voltage is adjusted by the revolving speed of rotor again, all has the coil being wrapped about on general rotor, it will be understood that
To be the watt level for determining generator by the coil amount wound on rotor, wound on existing rotor it is mostly be by circular copper wire
The coil being wound, but on the identical winding space of rotor, have air gap between circular copper wire and circular copper wire, can not only lead
The reduction of uniform space utilization rate reduces the power of motor, and can also improve cost.
Summary of the invention
For the coils being wound by circular copper wire being wound around on existing rotor, and deposited between circular copper wire and circular copper wire more
The problem of having air gap, not only result in the reduction of space utilization rate, reducing the power of motor, and can also improve cost, this is practical
It is novel to provide a kind of rotor structure for generator, can effectively improve space utilization rate, increase power of motor, reduce at
This.
Its technical solution is such that it includes rotor core, and the edge on the rotor core along its circumferencial direction is set
It is equipped with magnetic tooth, notch is formed between the adjacent magnetic tooth, is wound with copper wire on the magnetic tooth, it is characterised in that: the copper wire is adopted
With flat type copper wire, and lamination is wound on each magnetic tooth, and the magnetic tooth is in I-shaped.
It is further characterized by:
It is equipped with mounting hole at the rotor core center, is provided with positioning recess in the side inner wall of the mounting hole, it is described
There are multiple heat release holes along its circumferential directions on rotor core；
The notch between the adjacent magnetic tooth is equipped with bracket, and the bracket is in 7 fonts, the both ends point of the bracket
It is not fixed on the magnetic tooth of adjacent two；
The both ends end of the bracket is equipped with latch, and the magnetic tooth of the corresponding latch is equipped with corresponding bayonet, institute
The bottom end that bayonet is set to the magnetic tooth is stated, the bracket and the rotor core are surrounded by ventilation hole.
The utility model has the beneficial effects that being wound with flat type copper wire, and magnetic tooth by the magnetic tooth superimposed layer in rotor core
In I-shaped, then the sectional area of the coil formed on magnetic tooth by flat type copper wire can be effectively increased, the temperature rise of generator can be substantially reduced,
The calorific value for reducing copper wire not only increases space utilization rate in the same class of insulation, and increases the function of generator
Rate reduces costs.

Fig. 2 is the partial structural diagram of rotor core；
Fig. 3 is enlarged structure schematic diagram at the I of Fig. 1.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model includes rotor core 1, along the side of its circumferencial direction on rotor core 1
Edge is provided with magnetic tooth 2, and notch 3 is formed between adjacent magnetic tooth 2, and copper wire 4 is wound on magnetic tooth 2, and copper wire 4 uses flat type copper wire, and folded
Layer is wound on each magnetic tooth 2, and magnetic tooth 2 can be convenient for copper wire coiling in I-shaped.
It is equipped with mounting hole 5 at 1 center of rotor core, positioning recess 6 is provided in the side inner wall of mounting hole 5, is easily installed
It positions, has multiple heat release holes 7 along its circumferential directions on rotor core 1；Notch 3 between adjacent magnetic tooth 2 is equipped with bracket
8, bracket 8 is in 7 fonts, and the both ends of bracket 8 are individually fixed on two adjacent magnetic teeth 2；The both ends end of bracket 8 is equipped with latch
9, the magnetic tooth 2 of corresponding latch 9 is equipped with corresponding bayonet 10, and bayonet 10 is set to the bottom end of magnetic tooth 2, bracket 8 and rotor core 1
It is surrounded by ventilation hole 11.
