Description
Technical field
The utility model relates to motor fields, and in particular to a kind of large inertia motor.
Background technique
With permanent-magnet material, the development of power electronic technique, permanent-magnet servo motor more and more appears in various industry
In drive apparatus.
And with the development of industrial automation, various equipment are more and more intelligent and minimize.Therefore equipment is to servo electricity
The requirement of machine is higher and higher, such as: dynamic response is fast, power density is high etc..This requires that the volume of motor is smaller and smaller, this
Also it is as short as possible to be equivalent to motor motor axial length in the case where meeting performance indicator.
But it is different according to the load-carrying type of institute, when matching on different devices can inertia demand to motor not
Equally, some want small inertia, some want large inertia.Motor increases inertia there are mainly two types of method on the market at present:
(1) on the axis of permanent-magnet servo motor plus inertia disc, no matter this mode in shaft front end or rear end adds inertia disc,
Entire rotor length can all lengthen, and will lengthen so as to cause entire motor length；Therefore matched equipment installation space will
Become larger, bring complete equipment increased costs, and add the extended length also resulted in after inertia disc between two spring bearings, such as
When fruit motor application occasion demand revolving speed is higher, shaft degree of disturbing can become larger, and easily cause rotor and stator sweeps the risk of thorax；
(2) expand motor stator internal diameter, due to using different electromagnetic schemes, therefore each diameter of stator bore needs to set again
Meter, production and test are on probation, and the period is longer, and design cost is higher, and using after different electromagnetic schemes, need to be again to rotor
It carries out work, the higher cost such as being opened.
Utility model content
The utility model to solve the above-mentioned problems, to provide a kind of large inertia motor and its implementation.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
A kind of large inertia motor, the large inertia motor includes permanent-magnet servo motor, and the permanent-magnet servo motor is equipped with
Seperated encoder, the large inertia motor further include an inertia disc, the reflective gratings group of the inertia disc and seperated encoder
Part is cooperatively connected.
In a preferred embodiment of the utility model, the inertia disc is circular ring shape, the reflective gratings component
Including reflecting surface, the reflecting surface is equipped with connecting bracket, and the connecting bracket can be assigned into the inner hole of inertia disc.
In a preferred embodiment of the utility model, the inertia disc is equipped with Grating Film.
In a preferred embodiment of the utility model, reflective coating is pasted on the reflective gratings component.
In a preferred embodiment of the utility model, the inertia disc is wholely set with reflective gratings component
The beneficial effects of the utility model are:
While expanded motor inertia, motor axial length will not lengthen the utility model, can guarantee installation requirements, and
And make motor case, axis, stator and rotor cores etc. and can share small inertia machinery part, greatly save cost.
Detailed description of the invention

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1 to Fig. 4, large inertia motor provided by the utility model comprising permanent-magnet servo motor 100, seperated volume
Code device 200 and inertia disc 300.
The bracket and pcb component of seperated encoder 200 are mounted on permanent-magnet servo motor 100.
Inertia disc 300 is directly integrated with the installation of the reflective gratings component 210 of seperated encoder 200.
Reflective gratings component 210 specifically includes reflecting surface 211, and connecting bracket 212 is equipped on reflecting surface 211, and is used to
Amount disk 300 is circular ring shape, and connecting bracket 212 can assign into the inner hole of inertia disc 300, so that inertia disc 300 and anti-can be realized
Penetrate the detachable installation of formula grating assembly 210.
The bore depth of inertia disc 300 is specifically les than the length of connecting bracket 212, in this way, since inertia disc 300 is setting
In the connecting bracket 212 of reflective gratings component 210, in this way while expanded motor inertia, the axis of motor will not be changed
To length, and the installation of the axis of permanent-magnet servo motor 100 is not influenced also.
In addition, inertia disc 300 can also be wholely set with reflective gratings component 210, it is easily installed in this way.
It is equipped with Grating Film in inertia disc 300, reflective coating is pasted on reflective gratings component 210, can be passed through
Reflective coating reflection LED issues light source, and some light is projected by optical sensor, code device signal is generated.
The specific installation process of the application is as follows:
(1) first inertia disc 300 is first pressed into the connecting bracket 212 of reflective gratings component 210；
(2) Grating Film then is sticked in inertia disc 300；
(3) then permanent-magnet servo motor 100 is assembled, after assembling, then by the bracket and pcb of seperated encoder
Component 200 is mounted on the axis of permanent-magnet servo motor 100；
(4) then that the reflective gratings component 210 for being pressed with inertia disc 300 is axial along the axis of permanent-magnet servo motor 100
Push-in；
(5) finally encoder cover is installed.
Wherein, after the axial push-in of reflective gratings component 210, it need to guarantee reflective gratings component 210 and split type coding
The height of device 200 is corresponding.
In addition, can process on the axis of motor by the design of early period and reserve step, then inertia disc 300 will be housed
Reflective gratings component 210 is pushed into step along axial direction, is allowed to be fixed on axis, the bracket and pcb group of encoder seperated in this way
Part 200 can generate the coherent signal of encoder with reflective gratings component 210.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
