Abstract
The utility model discloses a novel towards piece heat radiation structure of high-speed motor, including towards the piece casing, be provided with towards the piece groove towards the distributing type on the piece casing, there is the electromagnetic wire towards the winding of piece inslot, the electromagnetic wire sets up keeping away from towards the one end of piece groove notch to the bottom of winding back electromagnetic wire and be equipped with one section space gap as motor heat dissipation channel towards between the piece groove notch, be equipped with the slot wedge that prevents the electromagnetic wire drunkenness towards the piece groove in electromagnetic wire bottom simultaneously. The utility model discloses compare in traditional heat radiation structure, the wind channel area is showing and is increasing, direct and electromagnetic wire and rotor contact, directly take away the heat from inside, and motor heat-sinking capability has obtained very big improvement, and motor weight can alleviate, has improved the power density of motor.
Description
Technical Field
The utility model relates to a high speed motor heat radiation structure especially relates to motor speed at 10000rpm ~ 100000rpm high rotational speed and hypervelocity application scenario.
Background
The high-speed motor has very high running frequency, the electromagnetic wire generates skin effect, the resistance is increased, the copper consumption is obviously increased, and a large amount of heat can be generated; the rotor is affected by high frequency, and the eddy current loss of the rotor is obviously increased and becomes a remarkable heat source of the motor. Because the high-speed motor is fast in rotating speed and high in power density, the motor is small in size and poor in heat dissipation performance, if heat generated by the electromagnetic wire and the rotor cannot be timely dissipated, the electromagnetic wire is burnt out, the rotor magnetic steel loses magnetism, the motor fails, and serious faults are generated. At present, a liquid cooling and simple internal ventilation heat dissipation structure is generally adopted for a high-speed motor, a heat dissipation channel is small, heat dissipation efficiency is low, the effect is poor, the motor is large in size, power density is low, the using amount of product materials is large, resource waste is caused, and the requirement of national energy conservation and emission reduction is not met.
SUMMERY OF THE UTILITY MODEL
Not enough to above-mentioned prior art exists, the utility model provides a novel towards piece heat radiation structure of high-speed motor.
The utility model adopts the technical proposal that: the utility model provides a novel towards piece heat radiation structure of high-speed motor, includes towards the piece casing, it is provided with towards the piece groove to go up the distributing type towards the piece casing, has the electromagnetic wire towards the winding of piece inslot, the electromagnetic wire sets up keeping away from towards the one end of piece groove notch to be equipped with one section space gap as motor heat dissipation channel after the winding between the bottom of electromagnetic wire and the piece groove notch, be equipped with the slot wedge that prevents the electromagnetic wire drunkenness towards the piece groove in electromagnetic wire bottom simultaneously.
Furthermore, a slot insulating part or a slot insulating part layer is arranged in a punching sheet slot of the electromagnetic wire winding part.
The utility model has the advantages that: adopt the technical scheme of the utility model, wind channel area is showing the increase, and direct and electromagnetic wire and rotor contact directly take away the heat from inside, and motor heat-sinking capability has obtained very big improvement, and motor weight can alleviate, has improved the power density of motor.
The utility model discloses a thermal simulation of Ansys calculates, selects suitable fan, and for traditional structure, its heat-sinking capability has improved 50%, and its motor volume can reduce more than 30%.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
labeled as: 1. a heat dissipation channel; 2. punching a sheet shell; 3. a slot wedge; 4. a slot insulator; 5. an electromagnetic wire.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a novel punching heat radiation structure of high-speed motor, including towards piece casing 2, towards piece casing 2 go up the distributing type and be provided with towards the piece groove, it has electromagnetic wire 5 to twine towards the piece inslot, electromagnetic wire 5 sets up the one end of keeping away from towards piece groove notch to be equipped with one section space gap as motor heat dissipation channel 1 between the bottom of winding back electromagnetic wire 5 and towards piece groove notch, be equipped with slot wedge 3 that prevents electromagnetic wire 5 drunkenness at the piece groove of punching of electromagnetic wire 5 bottom simultaneously, and be equipped with slot insulation or slot insulation layer in the piece inslot that the winding part of electromagnetic wire 5 twines.
In this embodiment, through with punching a slice cell type space split, partly be used for depositing the magnet wire, partly space is as the inside heat dissipation channel of motor, simultaneously through certain structural design, puts into the magnet wire below with slot wedge 3 and fastens it, prevents its drunkenness. Wherein, the size of the heat dissipation channel can be changed according to the actual situation, and the slot wedge 3 can move up and down.
The utility model discloses compare in traditional heat radiation structure, through the method of adopting towards the piece reservation heat dissipation channel, can be rapid direct take away the heat that the heat source produced, more direct than traditional pass through such route of electromagnetic wire, casing, the radiating efficiency is higher.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the scope of the present invention in any way, and all technical solutions obtained by using equivalent substitution modes and the like fall within the scope of the present invention.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
