Abstract

The utility model discloses a novel ventilation slot board structure for a motor rotor. The structure comprises a rotor end plate (1) and a tooth support (2) welded on the rotor end plate (1); the tooth support (2) adopts a ventilation channel; rectangular open slots (3) are formed in the axial direction of the tooth support (2); and convex slots (4) matched with the open slots (3) on a tooth pressure strip are formed at the tooth part and the yoke part of the rotor end plate (1). Due to adoption of the structure, the stacking factor of a rotor core is improved, the iron loss of a rotor is reduced, the running temperature of the rotor core is decreased, and the efficiency of a motor is increased. As the structure that the open slots on the tooth pressure strip are matched with the convex slots on the rotor end plate is adopted, the scratch to the coil of the rotor core caused by the tooth pressure strip which falls off is avoided.

Description

New-type electric machine rotor ventilation frid structure

Technical field

The utility model relates to a kind of motor rotor construction, relates in particular to a kind of New-type electric machine rotor ventilation frid structure.

Background technology

At present, for the current structure that adopts of rotor ventilation channel plate is to be cut into the wide steel plate bar of 10mm as the tooth pressure bar with sheet metal, be welded with the rotor end plates of the thick steel plate conduct of 1mm, the main problem that exists is: 1, because the contact area of tooth pressure bar and end plate welding is smaller, cause the welding deformation of end plate easily, reduce the stacking factor of rotor core, rotor iron loss rises, the rotor core heating.Electric efficiency reduces.2, because the tooth pressure bar is that steel plate processes, and its width dimensions is difficult to be consistent, the boss size Control that cooperates with end plate of tooth pressure bar is bad in addition, in the middle of the motor operation, cause tooth pressure bar obscission easily, the tooth pressure bar flies out, scratch stator and rotor cores coil, even cause scrapping of complete machine.

Summary of the invention

The purpose of this utility model provides a kind of stacking factor that can improve rotor core, and can prevent the New-type electric machine rotor ventilation frid structure that the tooth pressure bar comes off.

The problem of the required solution of the utility model realizes by the following technical solutions: it comprises rotor end plates and welding tooth support thereon, described tooth support adopts the ventilation channel-section steel, tooth support is provided with rectangular open slot at axial direction, and rotor end plates is provided with the concave slot that matches with tooth pressure bar open slot in tooth portion and yoke portion.

The said structure that the utility model adopts, because the tooth support width broadens, the contact area of itself and rotor end plates is big, the deformation ratio of some postwelding rotor is less, can improve the stacking factor of rotor core, and rotor iron loss descends, the operating temperature of rotor core descends, thereby improves efficiency of motor; Owing to adopted tooth pressure bar open slot and rotor end plates concave slot fit structure, can prevent the tooth pressure bar scratch stator and rotor cores coil that comes off.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Figure 1 shows that structural representation of the present utility model

Figure 2 shows that the left view of Fig. 1

Embodiment

By accompanying drawing as can be known, this New-type electric machine rotor ventilation frid structure comprises rotor end plates 1 and welding tooth support 2 thereon, described tooth support 2 adopts the ventilation channel-section steel, the thickness of ventilation channel-section steel is thicker than the steel plate that existing structure adopts, it is big that width when point is welded on the rotor end plates just becomes, increase the contact area with rotor end plates, can reduce the distortion of rotor.Tooth support 2 has rectangular open slot 3 at axial direction, and rotor end plates 1 is gone out the concave slot 4 that matches with tooth pressure bar open slot 3 in tooth portion and yoke portion, and open slot 3 matches with the concave slot 4 of projection can prevent tooth pressure sheet play radially.

Claims (1)

1. New-type electric machine rotor ventilation frid structure, comprise rotor end plates and welding tooth support thereon, it is characterized in that: described tooth support adopts the ventilation channel-section steel, tooth support is provided with rectangular open slot at axial direction, and rotor end plates is provided with the concave slot that matches with tooth pressure bar open slot in tooth portion and yoke portion.
