Abstract

The utility model discloses a variable-frequency direct-current motor, comprising a motor shaft, a shell, a rotor, a stator, a permanent magnet and a stator coil, wherein the permanent magnet is arranged on the rotor which is arranged on the motor shaft; and the stator coil is wound on the stator. The variable-frequency direct-current motor is characterized in that the stator comprises a plurality of iron cores which are installed in an embedding manner; and the stator coil is wound on the iron cores. The stator comprises twelve iron cores which are disc-shaped. The permanent magnet comprises a plurality of permanent magnet bodies which correspond to the iron core and are disc-shaped. The variable-frequency direct-current motor has the advantages of simple production technique and high generating efficiency.

Description

A kind of frequency conversion direct current machine
Technical field
The utility model relates to a kind of frequency conversion direct current machine, the frequency conversion direct current machine that specifically a kind of production technology is simple, generating efficiency is high.
Background technology
At present, direct current machine is widely used in all trades and professions, existing direct current machine mainly is made up of arbor, shell, rotor, stator, permanent magnet and stator coil, rotor, stator, permanent magnet and stator coil are positioned at shell, permanent magnet is arranged on the rotor, rotor is installed on the motor shaft, and stator coil is wrapped on the stator.There is complex manufacturing in existing direct current machine, produces and the low shortcoming of generating efficiency.How to reduce the complex manufacturing degree, improve and produce the focus that becomes the industry concern with generating efficiency.
Summary of the invention
The purpose of this utility model provides the frequency conversion direct current machine that a kind of production technology is simple, generating efficiency is high.
The purpose of this utility model is achieved through the following technical solutions.
A kind of frequency conversion direct current machine, comprise motor shaft, shell, rotor, stator, permanent magnet and stator coil, permanent magnet is arranged on the rotor, rotor is installed on the motor shaft, stator coil is wrapped on the stator, it is characterized in that: described stator comprises several iron cores, and stator coil is twined in embedded installation between iron core and the iron core on the iron core.
Described stator comprises 12 iron cores, and iron core is a plate-like.
Described permanent magnet comprises several and the corresponding permanent magnet that is plate-like of iron core.
The utility model compared with prior art has the following advantages.
Disc type stator coil in the frequency conversion direct current machine described in the utility model, adopting iron core is inserted sector structure, and the coil winding production technology is simple, and 12 windings can separate independent coiling production, are merged into an integral body then.The utility model is different from the conventional DC variable-frequency motor, stator coil and p-m rotor all adopt tray type structure, this increases the power output that the cross-section of air gap long-pending (magnetic flux area) improves the motor unit volume greatly, has the high efficiency of direct current variable frequency motor in high power density output again concurrently.The utility model can be used as wind-driven generator simultaneously and uses, and it is little to have the wind-force of startup, and high characteristics are renderd a service in generating.

Fig. 2 is the structural representation of the utility model iron core;
Fig. 3 is the structural representation of the single iron core of the utility model;
Fig. 4 is the structural representation behind the single iron core winding around of the utility model.
Fig. 5 is the structural representation of the utility model permanent magnet.
Embodiment
Below in conjunction with accompanying drawing the utility model frequency conversion direct current machine is described in further detail.
To shown in Figure 5, frequency conversion direct current machine described in the utility model mainly is made up of with stator coil 6 motor shaft 1, shell 2, rotor 3, stator 4, permanent magnet 5 as Fig. 1.Shell comprises shell and lower casing, and last shell and lower casing are connected and fixed by bolt, forms a cavity between last shell and the lower casing, and rotor, stator, permanent magnet and stator coil are positioned at cavity.Stator comprises 12 iron cores 7, and iron core is a plate-like, and embedded installation between iron core and the iron core is twined stator coil on each iron core.Because iron core adopts inserted sector structure, the coil winding production technology is simple, and each winding can separate independent coiling production, is merged into an integral body then.Rotor is installed on the motor shaft, install on the rotor eight with the corresponding permanent magnet that is plate-like of iron core.Stator coil and p-m rotor all adopt tray type structure, and this increases the power output that the cross-section of air gap long-pending (magnetic flux area) improves the motor unit volume greatly, have the high efficiency of direct current variable frequency motor in high power density output again concurrently.The utility model can be used as wind-driven generator simultaneously and uses, and it is little to have the wind-force of startup, and high characteristics are renderd a service in generating.
