Abstract
The utility model relates to a motor provided with an overspeed switch and an encoder. The motor includes a motor body, a stator, a rotor, and a bearing rear cover. The bearing rear cover is connected with the tail of the motor body. The motor is characterized in that the bearing rear cover is provided with the overspeed switch; the overspeed switch is connected with a main shaft of the motor via a small shaft of the overspeed switch; a second shaft extension part of the overspeed switch is provided with the encoder; the overspeed switch is a double-shaft overspeed switch. The advantages are that the installation mode of the overspeed switch and the encoder of the motor are easy and reliable, the coaxiality of the motor, the overspeed switch, and the encoder is guaranteed, and the operability is strong; the speed of the motor can be limited, and the safety hidden trouble caused by the slide hook of a main lifting motor of a crane is prevented.
Description
Technical field
The utility model belongs to the motor technology field, particularly relates to a kind of motor with overspeed switch and encoder.
Background technology
At present, along with social industrial expansion, the control of motor seems more and more important.Encoder is the most frequently used a kind of control element in Electric Machine Control.In the operational environment that has, also need the speed of motor is limited, when hanging motor as being used for the crane master, in order to prevent the main motor slide hook that hangs, therefore need to adopt overspeed switch to prevent the hypervelocity of motor speed, it is very difficult that encoder and two control elements of overspeed switch are installed on the motor simultaneously.
Summary of the invention
The utility model provides a kind of motor with overspeed switch and encoder for solving the technical problem that exists in the known technology, and this motor can be installed overspeed switch and encoder simultaneously.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of motor with overspeed switch and encoder, comprise motor body, stator, rotor and bearing bonnet, the bearing bonnet is connected to the afterbody of motor body, it is characterized in that: on the described bearing bonnet overspeed switch is installed, overspeed switch links to each other with electric machine main shaft by the little axle of overspeed switch, the second shaft extension at overspeed switch is equipped with encoder, and described overspeed switch is the twin shaft overspeed switch.
The utility model can also adopt following technical scheme:
Described overspeed switch, encoder and motor shaft are the axiality structure.
Advantage and the good effect that the utlity model has are:
After the utility model has adopted above technical scheme, the second shaft extension place of Double shaft-extension overspeed switch dress encoder, overspeed switch is installed in motor bearings and covers outward, and the little axle of overspeed switch connects overspeed switch axle and electric machine main shaft.This kind structure mounting means is easy, reliable, not only can guarantee the axiality of motor, overspeed switch, encoder, has very strong operability; But also can carry out speed limit to motor, slip the potential safety hazard that hook and the hook that slips cause to prevent the main motor that hangs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, motor body; 2, bearing bonnet; 3, the little axle of overspeed switch; 4, overspeed switch; 5, encoder.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of motor with overspeed switch and encoder, comprise motor body 1, stator, rotor and bearing bonnet 2, the bearing bonnet is connected to the afterbody of motor body, on the described bearing bonnet 2 overspeed switch is installed, overspeed switch 4 links to each other with electric machine main shaft by the little axle 3 of overspeed switch, and encoder 5 is installed on the second shaft extension of overspeed switch 4, in the present embodiment, described overspeed switch 4 is the twin shaft overspeed switch.
Operating principle of the present utility model is:
The second shaft extension place dress encoder of twin shaft overspeed switch, overspeed switch is installed on the motor bearings bonnet, and the little axle of overspeed switch connects overspeed switch axle and electric machine main shaft.This mounting means is easy, reliable, can guarantee the axiality of motor, overspeed switch, encoder, has very strong operability.
By above-mentioned mounting means, can realize that overspeed switch and encoder are installed on the motor simultaneously, in order to can better control motor.
Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model has been done all belong to the category of the technical solution of the utility model.
