Abstract

The invention discloses a punching sheet magnetic pole permanent magnet motor rotor which comprises a rotor sheet, wherein the rotor sheet is formed by punching an inner circular sheet retained by punching a stator sheet and is provided with a shaft hole; a main shaft is installed in the shaft hole; and a permanent magnet is fixed outside the rotor sheet. By punching the rotor sheet through utilizing the inner circular sheet retained by punching the stator sheet, the punching sheet magnetic pole permanent magnet motor rotor can fully utilize a silicon steel sheet material and simultaneously utilize simple and easy punching process instead of troublesome and difficult finish machining process of various machine tools, thereby reducing the production cost and being convenient for mass production.

Description

A kind of punching sheet magnetic pole permanent magnet motor rotor
Technical field
The present invention relates to a kind of permanent magnet machine rotor.
Background technology
Developing rapidly of magneto, its rotor structure be variation also.In the prior art, be processed into the magneto of magnetic pole with magnet steel, the interior disk that stays behind its punching out stator piece will be made other purposes, and utilance is not high.Be processed into magnetic pole with magnet steel, need in its course of processing with multiple lathe (for example sawing machine, forging and pressing bed, lathe, planer, milling machine, grinding machine or machining center etc.), employing the skilled worker carries out hard to tackle work flow, and production efficiency is not high.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of permanent magnet machine rotor that utilizes the interior disk punching out rotor sheet that stays behind the punching out stator piece, and material is fully used.
In order to solve the problems of the technologies described above, a kind of punching sheet magnetic pole permanent magnet motor rotor of the present invention comprises rotor sheet, described rotor sheet is formed by the remaining interior disk punching out of punching out stator piece, have axis hole in the rotor sheet, main shaft is installed in the axis hole, the rotor sheet outside is fixed with permanent magnet.
As improvement of the technical scheme, the described shaft hole inner wall and the main shaft outside are respectively arranged with first, second keyway, in this first, second keyway flat key are installed.
As improvement of the technical scheme, the arranged outside of described rotor sheet has cavity, and described permanent magnet is inlaid in this cavity; Have the through hole that runs through two end face on the described rotor sheet, two end faces of rotor sheet are respectively arranged with first, second pressing plate, and the locating pin of fixing first, second pressing plate is installed in the described through hole.
The invention has the beneficial effects as follows: this punching sheet magnetic pole permanent magnet motor rotor is owing to adopt said structure, utilize the remaining interior disk punching out rotor sheet of punching out stator piece, can make full use of silicon steel material, simultaneously can utilize easy punching production flow process, replace the Precision Machining production procedure of hard to tackle multiple lathe, thereby reduce production costs, be convenient to produce in batches.
