Abstract
The utility model relates to a motor rotor structure and especially relates to a ventilation slot board structure of a motor rotor. The ventilation slot board structure comprises a rotor shaft, a rotor core, ventilation slot boards and welding ribs, wherein the rotor shaft is sheathed in a through hole of the rotor core, the welding ribs are evenly distributed and fixed on the rotor shaft, the ventilation slot boards are evenly distributed on the rotor core, and the distance between each ventilation slot board corresponding to a welding rib and the welding rib on the rotor core is 17mm. The ventilation slot board structure of the motor rotor, provided by the utility model, has a good ventilation effect and can be adopted to greatly improve the ventilation quality of the rotor core and effectively control the temperature rise of the rotor.
Description
Technical field
The utility model relates to a kind of motor rotor construction, particularly relates to a kind of rotor ventilation channel plate structure.
Background technology
The motor internal cooling air passes through internal fan, wherein a part enters the rotor ventilation hole by axis hole again, usually on rotor axis of electric, the weldering muscle is arranged, ventilation channel plate over against the weldering muscle is very near apart from the weldering muscle, cause like this part that ventilation channel plate is corresponding with the weldering muscle substantially very close to each other, cause ventilating and be obstructed, more serious causing is substantially stuffy, cause the temperature of rotor to raise, affect the cooling effect of rotor core.
Summary of the invention
The utility model, in order to address the above problem, provides a kind of ventilation effect good, can be very large improve rotor core ventilation quality, effectively control a kind of rotor ventilation channel plate structure that rotor heats up.
The technical solution of the utility model is:
A kind of rotor ventilation channel plate structure, comprise armature spindle, rotor core, ventilation channel plate and weldering muscle, described rotor axle sleeve is connected in the through hole of rotor core, the weldering muscle is uniformly distributed and is fixed on armature spindle, ventilation channel plate is evenly distributed on rotor core, and ventilation channel plate corresponding with the weldering muscle on described rotor core is 17mm with the distance of weldering muscle.
The described number that is uniformly distributed and is fixed on the weldering muscle on armature spindle is 6.
Useful good effect of the present utility model is:
Ventilation channel plate corresponding with the weldering muscle on the utility model rotor core adopts short frid, be that distance between the outer wall of the bottom of ventilation channel plate and weldering muscle is for 17mm, distance between remaining ventilation channel plate bottom and weldering muscle outer wall is 7mm, effectively improve the ventilation quality of motor, reduce the temperature of rotor core, avoid rotor to break down because of excess Temperature in running.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Figure 1, the meaning of number in the figure representative is: 1 ventilation channel plate, 2 weldering muscle, 3 armature spindles, 4 rotor cores.
A kind of rotor ventilation channel plate structure, comprise armature spindle 3, rotor core 4, ventilation channel plate 1 and weldering muscle 2, described rotor axle sleeve is connected in the through hole of rotor core, the weldering muscle is uniformly distributed and is fixed on armature spindle, ventilation channel plate is evenly distributed on rotor core, and ventilation channel plate corresponding with the weldering muscle on described rotor core is 17mm with the distance of weldering muscle.
The described number that is uniformly distributed and is fixed on the weldering muscle 2 on armature spindle is 6.
Claims (2)
1. a rotor ventilation channel plate structure, comprise armature spindle, rotor core, ventilation channel plate and weldering muscle, described rotor axle sleeve is connected in the through hole of rotor core, the weldering muscle is uniformly distributed and is fixed on armature spindle, ventilation channel plate is evenly distributed on rotor core, it is characterized in that: ventilation channel plate corresponding with the weldering muscle on described rotor core is 17mm with the distance of weldering muscle.
