Abstract
The utility model relates to a rotor punching sheet with closed grooves. The rotor punching sheet comprises a rotor punching sheet body. A plurality of closed grooves are uniformly arranged on a circumference inside the rotor punching sheet body. The rotor punching sheet has a novel structure and is convenient to manufacture. The rotor punching sheet with a structure of the closed grooves uniformly arranged on the circumference inside the rotor punching sheet body enables the consumption amount of enamelled wires to be minimized. In addition, the closed grooves are low in tooth harmonic wave to allow harmonic wave loss and harmonic wave torque to be reduced, thereby minimizing stray loss.
Description
Technical field
The utility model relates to a kind of rotor punching, particularly a kind of closed slot rotor punching.
Technical background
At present traditional rotor punching majority adopts open slots, is provided with the rotor punching of this open slot, often is applied to the relatively high power motor, its enamelled wire large usage quantity, the slot ripples of open slot is relatively large, so that harmonic loss and harmonic torque are also larger, power loss is large when causing moving.
Summary of the invention
Purpose of the present invention is exactly in order to solve the weak point in the background technology, a kind of closed slot rotor punching to be provided.
For achieving the above object, the present invention adopts following technical scheme: a kind of closed slot rotor punching, comprise the rotor punching body, and be evenly equipped with some closed slots on the described rotor punching body inner rim.
For a kind of optimization of the present utility model, rotor punching body inner rim is provided with 30 groups of closed slots.
The present invention compares with background technology, and novel structure is easily manufactured, rotor punching body inner rim is evenly equipped with the closed slot of sealing, and the rotor punching of this structure can reduce the enamelled wire consumption, and the slot ripples of closed slot is less in addition, so that harmonic loss and harmonic torque can reduce, thereby reduce stray loss.
Description of drawings
Fig. 1 is the structural representation of closed slot rotor punching.
Embodiment
Embodiment 1: with reference to Fig. 1.A kind of closed slot rotor punching comprises rotor punching body 1, is evenly equipped with some closed slots 2 on described rotor punching body 1 inner rim.
On the basis of above-described embodiment, rotor punching body 1 inner rim is provided with 30 groups of closed slots 2.
Above-described only is preferred implementation of the present utility model; should be understood that; for those of ordinary skill in the art; under the prerequisite that does not break away from core technology feature of the present invention; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
