Abstract
The invention discloses a rotor punching sheet of a high-speed permanent magnet motor. The rotor punching sheet comprises punching sheet inner slots (1), punching sheet combined holes (2), lightening holes (3) and a rotor shaft hole (4), wherein the punching sheet inner slots (1) are distributed on an outer circumferential surface of the punching sheet, the lightening holes (3) are arranged around the rotor shaft hole (4) in a surrounding manner, the punching sheet combined holes (2) are arranged among the lightening holes (3), and the rotor shaft hole (4) is arranged at the center of the punching sheet. According to the rotor punching sheet of the high-speed permanent magnet motor disclosed by the invention, a permanent magnet block is embedded in the punching sheet inner slot so that the permanent magnet block can be prevented from falling off during a high-speed operation; due to an integrated punching sheet structure, a magnetic flux forms closed circulation so as to prevent the permanent magnet block from loss of excitation, and the service life of the permanent magnet motor is prolonged; and reverse installation of the punching sheet is avoided by utilizing asymmetrical webs in the punching sheet.
Description
Technical field
The present invention relates to a kind of high-speed permanent magnetic motor rotor punching slice.
Background technology
In the prior art; The punching of motor rotor is not provided with the punching inside groove; The permanent magnets of rotor is to be directly installed on the rotor outside or to pass through the baffle plate retaining in rotor periphery, and little in the very little situation of motor air gap like this, loosening permanent magnets very likely surpasses air gap; It is stuck to send a telegraph motivation, and complete machine is scrapped.
Summary of the invention
The purpose of this invention is to provide a kind of high-speed permanent magnetic motor rotor punching slice that prevents that permanent magnets from running up and coming off.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of high-speed permanent magnetic motor rotor punching slice; Comprise punching inside groove (1), punching combination bore (2), lightening hole (3) and rotor shaft hatch (4); Said punching inside groove (1) is distributed on the outer circumference surface of punching; Said lightening hole (3) is around being distributed in rotor shaft hatch (4) all around, and said punching combination bore (2) is arranged between the lightening hole (3), and rotor shaft hatch (4) is arranged on the center of punching.
Said lightening hole (3) is fan-shaped.
A kind of high-speed permanent magnetic motor rotor punching slice of the present invention, permanent magnets is installed in the punching inside groove, can prevent that permanent magnets from running up to come off; Whole punching structure; Make magnetic flux form closed cycle, stop the permanent magnets loss of excitation, prolong permanent magnet motor useful life; Utilize the inner asymmetric former of punching, avoid punching oppositely to install.
Description of drawings
Fig. 1 is the structural representation of a kind of high-speed permanent magnetic motor rotor punching slice of the present invention.
Among the figure: 1, punching inside groove; 2, punching combination bore; 3, lightening hole; 4, rotor shaft hatch.
Embodiment
As shown in Figure 1, the high-speed permanent magnetic motor rotor punching slice comprises punching inside groove 1, punching combination bore 2, lightening hole 3 and rotor shaft hatch 4; Punching inside groove 1 is distributed on the outer circumference surface of punching, and lightening hole 3 is around being distributed in around the rotor shaft hatch 4, and punching combination bore 2 is arranged between the lightening hole 3; Rotor shaft hatch 4 is arranged on the center of punching, and lightening hole 3 is fan-shaped, high-speed permanent magnetic motor rotor punching slice of the present invention; Permanent magnets is installed in the punching inside groove, can prevent that permanent magnets from running up to come off whole punching structure; Make magnetic flux form closed cycle, stop the permanent magnets loss of excitation, prolong permanent magnet motor useful life; Utilize the inner asymmetric former of punching, avoid punching oppositely to install.
Claims (2)
