Abstract
The utility model provides a novel inner magnetic rotor for a DC brushless motor, wherein the front end and the rear end of the inner magnetic rotor are respectively sheathed with a rotor core, and an inner magnetic conduction ring is bonded on the outer wall of inner magnetic steel of the inner magnetic rotor. According to the utility model, the inner magnetic conduction ring is bonded on the outer wall of the inner magnetic steel of the inner magnetic rotor, which increases the magnetic field intensity greatly, thereby being capable of reducing stator windings dramatically, reducing heat produced by the windings, and enabling the motor to keep running with a high speed for a long time. The operation is stable and the efficiency is high. Meanwhile, the amount of copper wires used is reduced, thereby being energy saving, environmental friendly and low in power consumption.
Description
[technical field]
The utility model relates to machine field, particularly a kind of novel interior magnet rotor for dc brushless motor.
[background technology]
Existing dc brushless motor is when work; owing to will reach and run up; have to improve motor speed by increasing stator winding; this has just increased the consumption of power consumption and copper, and motor generally all is in the state that runs up for a long time, increases stator winding and must strengthen heat dissipation capacity; thereby cause motor temperature high; be out of order easily, must could work by intermittently shutting down heat radiation, this has just affected operating efficiency greatly.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of novel interior magnet rotor for dc brushless motor, and it has solved for a long time high-speed cruising problem of existing dc brushless motor.
The utility model is achieved in that
Be used for the novel interior magnet rotor of dc brushless motor, the front-end and back-end of described interior magnet rotor are a sheathed rotor core respectively, the outer wall of the interior magnet steel of the described interior magnet rotor interior magnetic conductance magnet ring that bonds.
Further, described interior magnetic conductance magnet ring is the rare earth ring.
The utility model has the advantage of: by the interior magnetic conductance magnet ring that bonds of the outer wall at the interior magnet steel of interior magnet rotor, it has increased magnetic field intensity greatly, thereby can significantly reduce stator winding, thereby reduced the caloric value of winding, make motor keep for a long time running up, stable working efficient is high, reduces simultaneously the use of copper cash, energy-conserving and environment-protective and low in energy consumption.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
[embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
The novel interior magnet rotor 1 that is used for dc brushless motor, the front-end and back-end of described interior magnet rotor 1 respectively among sheathed rotor core 11(Fig. 1 the rotor core 11 of rear end fixed by a fixture), the outer wall of the interior magnet steel 12 of the described interior magnet rotor interior magnetic conductance magnet ring 13 that bonds.Described interior magnetic conductance magnet ring 13 is the rare earth ring.
By the interior magnetic conductance magnet ring 13 that bonds of the outer wall at the interior magnet steel 12 of interior magnet rotor 1, it has increased magnetic field intensity greatly, thereby can significantly reduce stator winding, thereby reduced the caloric value of winding, make motor keep for a long time running up, and stable working is also increased work efficiency, and reduces simultaneously the use of copper cash, energy-conserving and environment-protective and low in energy consumption.
The above, it only is the utility model preferred embodiment, so can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
