Embodiment 1

[0028] Such as figure 2 As shown, the present invention discloses a cast aluminum rotor alveolar structure, including an alveolar body, an insulating partition 12 is arranged in the cavity of the alveolar body; The wall 111 is connected or contacted, and the first end surface 121 extends to the second end surface 122 along the length direction of the alveolar body; the second end surface 122 is connected or contacted with the other end wall 112 of the alveolar body, and the bottom of the insulating partition 12 is in contact with the other end wall 112 of the alveolar body. The bottom wall 113 of the alveolar body is connected.

[0029] The present invention compares with figure 1 In the prior art shown, the width of the alveolar body is reduced by arranging an insulating partition 12 inside the alveolar body, according to the Ampere loop theorem It is known that under the condition of constant rotor current, by shortening r, the magnetic induction intensity is increased, ...

Embodiment 2

[0032] Such as figure 2 , 3 As shown, the present invention discloses a cast aluminum rotor alveolar structure, including an alveolar body, an insulating partition 12 is arranged in the cavity of the alveolar body; The wall 111 is connected or contacted, and the first end surface 121 extends to the second end surface 122 along the length direction of the alveolar body; the second end surface 122 is connected or contacted with the other end wall 112 of the alveolar body, and the bottom of the insulating partition 12 is in contact with the other end wall 112 of the alveolar body. The bottom wall 113 of the alveolar body is connected. The number of insulating partitions 12 is an odd number, and several insulating partitions 12 are equidistantly distributed. The central axis of the middlemost insulating partition 12 coincides with the central axis of the alveolar body.

[0033] The electromagnetic torque of the initial non-segmented cast aluminum groove is set to an index of 1...

Embodiment 3

[0039] Such as figure 2 , 3 As shown, the present invention discloses a cast aluminum rotor alveolar structure, including an alveolar body, an insulating partition 12 is arranged in the cavity of the alveolar body; The wall 111 is connected or contacted, and the first end surface 121 extends to the second end surface 122 along the length direction of the alveolar body; the second end surface 122 is connected or contacted with the other end wall 112 of the alveolar body, and the bottom of the insulating partition 12 is in contact with the other end wall 112 of the alveolar body. The bottom wall 113 of the alveolar body is connected.

[0040] The bottom wall 113 of the alveolar body is provided with a slot (not shown in the figure), and the bottom of the insulating partition 12 is engaged in the slot or the bottom wall 113 of the alveolar body is bonded to the bottom of the insulating partition 12 by an adhesive. combine.

[0041] The insulation partition 12 is pre-positione...

Abstract

The invention discloses a cast-aluminum rotor gullet structure, which comprises a gullet body. Insulating separator plates are arranged in a cavity of the gullet body. The first transverse plane of each insulating separator plate is connected or contacted with one end wall of the gullet body, and extends in a length direction of the gullet body to the second transverse plane. The second transverse plane of each insulating separator plate is connected or contacted with the other end wall of the gullet body. The bottom of each insulating separator plate is connected with the bottom wall of the gullet body. The advantages are that in a condition with the same electric magnetic torque, currents of a rotor are reduced, currents of a corresponding stator are reduced, and thus the efficiency of a motor is increased.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a cast aluminum rotor tooth slot structure. Background technique [0002] High Efficiency Motor (High Efficiency Motor) refers to a motor with high efficiency, and its efficiency should meet the relevant energy efficiency level requirements. Starting from saving energy and protecting the environment, high-efficiency motors are the current international development trend, and the United States, Canada, and Europe have successively promulgated relevant laws and regulations. According to the running time of the electric motor, the European CEMEP standard divides the efficiency into three levels: eff1 (highest), eff2, and eff3 (lowest), which will be implemented step by step from 2003 to 2006. The latest IEC60034-30 standard divides motor efficiency into four levels: IE1 (corresponding to eff2), IE2 (corresponding to eff1), IE3, and IE4 (the highest). Our country promises t...
