Abstract
The utility model relates to an overload control device for a motor, comprising a rotor and a motor end cover, wherein a shaft rod is connected between the rotor and the motor end cover; one end of the shaft rod penetrates through the motor end cover; a centrifugal piece, a centrifugal transversing device and a switch board are sheathed in sequence from the left to the right on the shaft rod between the rotor and the motor end cover; the switch board is fixed on the motor end cover; and the centrifugal piece is fixed on the shaft rod by a centrifugal piece spring. The overload control device has the advantages that the structure is simple and the installation and the maintenance are convenient, the defects of low sensitivity and poor stability of the traditional motor protector are changed, and the overload control device can play a protecting role in high-frequency faults such as overload, short circuit and default phase and the like of the motor.
Description
Technical field:
The utility model relates to a kind of overload control device that is used for motor.
Background technology:
At present,, require again to reduce volume, make the thermal capacity of New-type electric machine more and more littler because the continuous development of insulation technology had both required to increase in the design of motor and exerted oneself, capability of overload more and more a little less than; Because the raising of production automation degree; require motor often to operate in multiple modes such as frequent starting, braking, rotating and varying duty; electric motor protective device is had higher requirement; traditional electric motor protective device; electrical equipment sensitivity is low, error big, poor stability, and it is unreliable to protect.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, motor overload control device a kind of simple in structure, easy for installation to be provided.
The purpose of this utility model is achieved through the following technical solutions: comprise rotor and electric motor end cap, between rotor and electric motor end cap, be connected with axostylus axostyle, and an end of axostylus axostyle is through electric motor end cap, between rotor and electric motor end cap, on axostylus axostyle, be with centrifugal film, centrifugal traversing gear, switchboard from left to right successively, and switchboard is fixed on the electric motor end cap, and centrifugal film is fixed on the axostylus axostyle by the centrifugal film spring.
The utility model compared with prior art has the following advantages:
Have simple in structure, installation and maintenance advantage easily, changed low, the poor stability of sensitivity of conventional motors protector, more reliable protection motor.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: 1-rotor, 2-axostylus axostyle, 3-centrifugal film, 4-centrifugal film spring, the centrifugal traversing gear of 5-, 6-switchboard, 7-End cover for motor.
Embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection range.
As Fig. 1; 2 show a kind of overload control device that is used for motor of the utility model; comprise rotor 1 and electric motor end cap 7; between rotor 1 and electric motor end cap 7, be connected with axostylus axostyle 2; and an end of axostylus axostyle 2 is through electric motor end cap 7; between rotor 1 and electric motor end cap 7, on axostylus axostyle 2, be with centrifugal film 3 from left to right successively; centrifugal traversing gear 5; switchboard 6; and switchboard 6 is fixed on the electric motor end cap 7; centrifugal film 3 is fixed on the axostylus axostyle 2 by centrifugal film spring 4; on switchboard 6, draw A; two lines of B are led; when using this device on threephase motor; with A; B two node strings are received on the self-sustaining node; when motor overload turns round; centrifugal film 3 inertia of centrifugal force reduce and by centrifugal film spring 4 move to centrifugal film 3 and the position on; centrifugal traversing gear 5 actions; make A; B disconnects, thereby plays motor overload; short circuit; the protective effect of high-frequency faults such as phase shortage.
