Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, rotor punching of the present utility model and motor are further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A motor, comprises rotor (not shown), and rotor comprises the rotor core (not shown) being overrided to form by a plurality of rotor punchings.
Wherein rotor punching, as shown in Figure 1, 2, comprises punching body 1, and on the periphery of punching body 1, uniform setting is in order to be wound around the teeth groove 2 of rotor coil;
Teeth groove 2 comprises the first teeth groove portion 3 and the second teeth groove portion 4;
The first teeth groove portion 3 comprises the first trough rim 5 and the second trough rim 6 that is symmetrical arranged and is parallel to each other;
The second teeth groove portion 4 comprises that the 4th trough rim 8 of the 3rd trough rim 7 and the 4th trough rim 8, the three trough rims 7 and adjacent sheaves 2 is parallel.
Such the first teeth groove portion 3 is parallel slot structure, the second teeth groove portion 4 is parallel teeth structure, make rotor punching can have the advantage of parallel slot structure and parallel toothing concurrently, and grooved is narrow and dark, notch leakage reactance is less, and electric current is larger, form the kelvin effect of electric current, the supplementary load loss that reduced motor, have increased detent torque, and integral body has improved the performance of motor.
As a kind of embodiment, punching body 1 centre arranges endoporus 9, and punching body 9 is sleeved on motor shaft by endoporus 9, and keyway 10 is set on endoporus 9, for by key by punching body 1 and motor shaft relative positioning.The keyway corresponding with keyway 10 can be set on motor shaft, and rotor punching is located by key and motor shaft when mounted, can guarantee accuracy and the fastness of installation, thereby has guaranteed the normal operation of motor, has improved the quality of motor.
As a kind of embodiment, the length of the length of the first trough rim 5 and the second trough rim 6 and the 3rd trough rim 7 and the 4th trough rim 8, all suitable with external diameter and the internal diameter of punching body 1.
