Abstract
The utility model discloses an explosion-proof motor comprising a stator punching sheet body and a rotor punching sheet body which are matched with each other, wherein the stator punching sheet body is provided with a stator slot, the rotor punching sheet body is provided with a rotor slot, the diameter of an excircle of the stator punching sheet body is the same as the diameter of the excircle of the stator punching sheet body of a motor with a higher model, and the diameter of the excircle of the rotor punching sheet body is the same as the diameter of the excircle of the rotor punching sheet body of the motor with the higher model. In the utility model, the diameter of the excircle of the stator punching sheet body and the diameter of the excircle of the rotor punching sheet body with the higher models are adopted on the explosion-proof motor, and the stator slot and the rotor slot are also enlarged, so that more electromagnetic materials can be utilized as much as possible for optimizing the electromagnetic scheme so as to reduce various losses of the motor and more effectively improve the efficiency of the motor.
Description
Technical field
The utility model relates to fire-proof motor, relates in particular to the fire-proof motor of a kind of stator, rotor punching structural change.
Background technology
Like Fig. 1, shown in Figure 2, the stator of traditional fire-proof motor, rotor punching structure comprise stator punching body 1 and the rotor punching body 3 that cooperatively interacts, and stator punching body 1 is provided with stator slot 2, and establishing son on the rotor punching body 3 has rotor 4.In the fire-proof motor industry standard; Fire-proof motor is divided model with the motor center height; The stator punching body of the fire-proof motor of different height of center models and the outside diameter of rotor punching body are all inequality; As shown in table 1, be that the motor of YBXn225-2 is an example with the model, the outside diameter a1 of stator punching body is 368mm; The outside diameter b1 of rotor punching body 3 is 210mm, is that the motor model of the high height of center of motor of YBXn225-2 is YB3E250-2 than model, and the outside diameter of its stator punching body is 400mm; The outside diameter of rotor punching body is 225mm.In order to improve efficiency of motor, traditional scheme is for adding long stator and rotor core, thereby increases the use amount of electromagnetic material, reduce the wastage, and raise the efficiency, but this scheme effect is limited, and strengthened the manufacture difficulty of motor stator, rotor.
The utility model content
The purpose of the utility model provides a kind of fire-proof motor, can reduce the loss of electric machine, improves electric efficiency.
The utility model adopts following technical proposals: a kind of fire-proof motor; Comprise the stator punching body and the rotor punching body that cooperatively interact; The stator punching body is provided with stator slot; Establishing son on the rotor punching body has rotor, and the outside diameter of described stator punching body is identical with the outside diameter of the stator punching body of the fire-proof motor of a high height of center model, and the outside diameter of rotor punching body is identical with the outside diameter of the rotor punching body of the fire-proof motor of a high height of center model.
