Description

Motor and generator stator structure

The invention relates to a stator structure, in particular to a method for improving the groove ratio of the winding, increasing the torque, reducing the current, achieving the energy saving effect, and the mass production is simple and easy, the production efficiency is high, the cost is saved, and the The stator structure of the magnetic flux motor and generator.

There are many types of motors and generators, which are not repeated here. They are basically composed of a stator and a rotor. The stator is fixed in the casing of the motor, and the rotor is supported by a rotating shaft. And the proper distance from the stator, when the coil on the stator conducts a current, a magnetic field can be generated, and the magnetic field is mutually exclusive with the magnetic force of the magnet provided on the rotor to rotate the rotor and output power, which is the basic operation mode of the motor; When the rotor is rotated by force, the coil on the stator can be excited to generate current and output power, which is the operation mode of the generator.

At present, the stator structure of the motor and the generator is usually formed by overlapping a plurality of annular or frame-shaped silicon steel sheets to form a toroidal core (commonly called an electromagnet) having a plurality of winding-like bobbins, each winding. Between the columns is a winding groove, which is used to wind the coil. The silicon steel sheet is made by integral stamping. Because the stator composed of the silicon steel sheet has high performance, less magnetic loss and iron loss, it is quite affected by the motor. It is used by the manufacturing industry; however, because the steel sheet used to wind the coil has a T-shaped winding shape and is integrally stamped, the disadvantage is that the winding is difficult, and a special winding machine must be used. And the stamping of the steel sheet is also high in precision and expensive, so Manufacturing costs are quite high.

In addition, it is emphasized that the manufacture of a motor with high running efficiency, the manufacturing bottleneck is mostly caused by the problem of the winding of the exciting coil. Because the motor has high operating efficiency, it is necessary to strengthen the magnetic flux, increase the magnetic flux, and increase the torque. By reducing the current, the energy saving effect can be achieved, and increasing the number of windings of the winding groove in the stator structure (ie, increasing the slot ratio or saturation rate or the tank full rate) is the best way to enhance the magnetic field lines and increase the torque. Method.

Furthermore, there is also a gap in the press-fit method of the stator steel structure of the motor and the generator in the market, and the gap causes the magnetic flux to decrease.

Therefore, the stator structure of the motor and the generator is still not perfect, so the inventor continuously researches the concept of improvement and innovation based on the product, and is based on the practical experience of the product development for many years, as well as actively researching and thinking, through countless The second actual design experiment resulted in the production of the present invention.

Stator structure with generator.

Another object of the present invention is to provide a stator structure of a motor and a generator which is simple in mass production, high in production efficiency, and cost-effective.

It is still another object of the present invention to provide a stator structure for a motor and a generator that enhance magnetic flux.

For the above purposes, the present invention comprises a plurality of first component stacks and a plurality of second component stacks, wherein the first component is a silicon steel sheet material; the second component is a silicon steel sheet material. One side of the second component is movably disposed on a side of the first component, and the second component and the first component outer shape together define a plurality of bobbins and a plurality of windings between the bobbins a slot, and defining a two protrusion, the protrusion is disposed on a side of the winding slot for stopping the winding of the bobbin and the winding slot, the first component, the second component One part is overlapped and pressed.
