Abstract
The utility model discloses a kind of motor heat dissipation structure, it comprises stator punching (1), stator coil (2) and rotor punching (5), the upper one end near rotor punching (5) of stator punching (1) is provided with stator punching groove (6), the height of stator punching groove (6) exceeds the height of stator punching (1) and rotor punching (5), makes to be formed between stator inner circle and rotor outer circle and stator punching groove (6) the same number of air duct.It is simple that the utility model has structure, easily produces in batches, can effectively increase stator yoke magnetic close, the feature that punching utilance is high.
Description
Technical field
The utility model relates to a kind of electronic radiator structure, belongs to electric motor structure design field.
Background technology
In design motor procedure, heat radiation is one of major issue needing to solve.At present, traditional squirrel-cage motor by opening air holes or stator punching outside employing reinforcing rib structure formation air duct on stator and rotor punching, then carries out outside air circulation through forced air cooling device, reaches cooling effect.The motor of similar structure, air gap between rotor punching and stator punching is less, rotor punching is comparatively closed, air circulation is carried out by means of only air gap and ventilation hole and the external world, take away internal rotor heat as shown in Fig. 1 tradition squirrel-cage motor structure, but its effect can not show a candle to stator, the temperature of rotor still remains on higher level.Therefore in most cases, the temperature rise of the temperature rise ratio stator of rotor.
In order to the problem of electric machine temperature rise can better be solved, increase rotor core heat-sinking capability, need to extend the better electric motor structure of a kind of heat dispersion from traditional squirrel-cage motor structure.
Utility model content
The purpose of this utility model is to provide a kind of motor heat dissipation structure, solves the problem of motor stator and rotor dispersing thermal unbalance in prior art, decreases the windage of motor interior, enhance the heat radiation of motor interior, especially the heat radiation of rotor.
The purpose of this utility model is achieved through the following technical solutions: a kind of motor heat dissipation structure, it comprises stator punching (1), stator coil (2) and rotor punching (5), the upper one end near rotor punching (5) of stator punching (1) is provided with stator punching groove (6), the height of stator punching groove (6) exceeds the height of stator punching (1) and rotor punching (5), makes to be formed between stator inner circle and rotor outer circle and stator punching groove (6) the same number of air duct.
Described stator punching groove (6) is connected with stator coil (2) by slot wedge (3).
The height that described stator punching groove (6) increases is directly proportional to the difference of rotor temperature rise and stator temperature rise, and the heat can taken away needed for rotor determines the height that stator punching groove (6) increases.
The utility model has following beneficial effect:
1, by increasing the height of stator punching groove, making between motor stator and rotor, to form effective air duct, reducing motor interior windage, increase motor interior radiating efficiency, the especially radiating efficiency of rotor;
2, the height that stator punching groove increases is directly proportional to the difference of rotor temperature rise and stator temperature rise, therefore the heat taken away can be needed to determine the height that stator punching notch increases according to rotor, and the height that namely punching notch increases easily obtains;
3, the utility model has structure simply, easily produces in batches, can effectively increase stator yoke magnetic close, the advantage that punching utilance is high.
figure of description
Fig. 1 is traditional squirrel-cage motor structure;
Fig. 2 is the utility model electric motor structure;
Wherein, 1-stator punching, 2-stator coil, 3-slot wedge, 4-air gap, 5-rotor punching, 6-stator punching groove.
Embodiment
Be described in further detail the utility model below in conjunction with the drawings and specific embodiments, protection range of the present utility model is not limited to the following stated.
According to Fig. 2: a kind of motor heat dissipation structure, it comprises stator punching (1), stator coil (2) and rotor punching (5), the upper one end near rotor punching (5) of stator punching (1) is provided with stator punching groove (6), the height of stator punching groove (6) exceeds the height of stator punching (1) and rotor punching (5), makes to be formed between stator inner circle and rotor outer circle and stator punching groove (6) the same number of air duct; Described stator punching groove (6) is connected with stator coil (2) by slot wedge (3).
In addition, the height that stator punching groove (6) increases is directly proportional to the difference of rotor temperature rise and stator temperature rise, and the heat can taken away needed for rotor determines the height that stator punching groove (6) increases.
Claims (2)
