Abstract
The utility model discloses a permanent magnet positioning device in a permanent-magnet rectilinear synchronous motor, comprising a positioning plate body on which cavities for inserting permanent magnets are arranged. The structure of the utility model is reasonable, and thus the relative positions and the positioning accuracy between each permanent magnet can be sufficiently ensured. The flatness is favorable, and thus the stationarity of the propulsion of the permanent-magnet linear synchronous motor is favorable.
Description
Technical field:
The utility model relates to a kind of auxiliary of permanent-magnet linear motor.
Background technology:
The permanent-magnet linear synchronous machine has obtained more and more widely application as linear drive system in Digit Control Machine Tool, in other mechanisms, also begin to be applied.In the permanent-magnet linear synchronous machine (or claiming permanent magnetic synchronous electrical motor), permanent magnet is important part, and its quantity is more, how arranges the positioning accuracy degree, directly influences motor thrust stationary performance.Main by manual one by one that permanent magnet is gluing fixing in permanent magnet assembling in the past, because the magnetic field intensity of permanent magnet is very high, active force between adjacent is very big, make relative position and positioning accuracy between each permanent magnet be difficult to be guaranteed like this, evenness is relatively poor, has influenced the stationarity of permanent-magnet linear synchronous machine thrust.
Summary of the invention:
The purpose of this utility model is to provide a kind of relative position and positioning accuracy that can fully guarantee between each permanent magnet, evenness is good, thereby makes the permanent magnet positioner in the good permanent-magnet linear synchronous machine of the stationarity of permanent-magnet linear synchronous machine thrust.
Technical solution of the present utility model is:
Permanent magnet positioner in a kind of permanent-magnet linear synchronous machine is characterized in that: the location plate body is arranged, the cavity of setting-in permanent magnet is set on the plate body of location.
The cavity is a plurality of parallelogram forms that are arranged parallel to each other.Each cavity is and is combined into by adjacent two parallelogram in the left and right sides
Font, and be parallel to each other between the cavity up and down.
The utility model is rational in infrastructure, can fully guarantee relative position and positioning accuracy between each permanent magnet, and evenness is good, thereby makes the stationarity of permanent-magnet linear synchronous machine thrust good.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of embodiment 1.
Fig. 2 is the configuration diagram of embodiment 2.
Embodiment:
Permanent magnet positioner in a kind of permanent-magnet linear synchronous machine has polyethylene location plate body 1, and the cavity 2 of setting-in permanent magnet is set on the plate body 1 of polyethylene location.The cavity is a plurality of parallelogram forms that are arranged parallel to each other.
Embodiment 2:
Permanent magnet positioner in a kind of permanent-magnet linear synchronous machine has polyethylene location plate body 3, and the cavity 4 of setting-in permanent magnet is set on the plate body 3 of polyethylene location.Each cavity is and is combined into by adjacent two parallelogram in the left and right sides
Font, and be parallel to each other between the cavity up and down.
Claims (3)
1, the permanent magnet positioner in a kind of permanent-magnet linear synchronous machine is characterized in that: the location plate body is arranged, the cavity of setting-in permanent magnet is set on the plate body of location.
