Description
Technical field
The present invention relates to a kind of driving part of sewing device, particularly a kind of stator and rotor split for sewing machine
Formula motor.
Background technology
Electric motor structure at present, mainly have following two：
The first：Motor includes bearing, drive end bearing bracket, rear end cap, solid shafting, encoder and grating assembly.Using stator
In casing, drive end bearing bracket and rear end cap are fixed hot jacket after being coordinated by casing with screw.Casing needs in process
To be draw textured from aluminium bar, Ageing Treatment need to be also carried out in isoperibol, sandblasting is also needed before casing is made by section bar factory
Anodized；Therefore, it is necessary to consume substantial amounts of electric energy, so as to increasing the row of carbon during from aluminium bar to casing
Put；In order to ensure casing surface quality after casing shaping, the processing such as sandblasting anodic oxidation need to be also carried out on casing surface.So meeting
Surrounding environment is polluted；Also need to carry out metalworking to casing in motor manufacturing enterprise, needed when stator coordinates with casing
To use hot cover process.
Second is permanent magnet motor, it include bearing, drive end bearing bracket, rear end cap, solid shafting, encoder, grating assembly, after
Cover and control section.Wherein, positioning is fixed by the cylindrical and plane of inner stopper and stator core with rear end cap in drive end bearing bracket,
It is fixed thereafter by screw.This scheme exist temperature rise is higher, became uneven of stator silicon steel plate and cause the length of motor
Spend dimensional variations it is very big, Motor Shaft size is difficult to ensure that, and can make front and rear cover because stator core it is not parallel cause not
It is parallel；It is on the high side to also result in bearing noise.
In addition, also there is following deficiency for the existing motor of above two：
Integrally 1. the part as sewing machine, stator or rotor cannot function as single parts to motor.
2. machine spindle is that shaft coupling is coupled with motor shaft, so that the axial dimension of sewing machine is big, will take
More spaces.In addition, the rotary inertia of shaft coupling itself is big, acceleration is poor, has certain restriction to sewing speed, and sewed
Cheng Zhong, energy consumption are big.
3. motor is felt relieved by the boss and end face of drive end bearing bracket with the seam that couples set on head of sewing machine, after
Motor drive end bearing bracket is fixed on by head of sewing machine by screw.This mode, namely occur that temperature rise is higher, stator silicon steel plate
Became uneven and cause motor length dimension change it is very big, Motor Shaft size is difficult to ensure that, and can make front and rear cover because
Stator core not parallel and cause not parallel；It is on the high side to also result in bearing noise.
4. encoder, grating assembly are split part, between the two without mechanical coupling part.So, in grating assembly
Lenticular lenses can not ensure uniformity with the position in encoder optocoupler, can cause to report an error in encoder operation process.
5. the both ends of motor rotor shaft are respectively set with bearing, bearings at both ends inserts the bearing of drive end bearing bracket and rear end cap respectively
Room.So, motor meeting bearing damage caused by the life-span of bearing grease or external force etc., can make motor in long-term operation process
The reduction of service life because of the damage of bearing, while will also result in bearing noise in normal assembling process.
The content of the invention
In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a kind of for sewing machine
Stator and the split type motor of rotor, this is used for the stator of sewing machine and the split type motor of rotor, and axial dimension is small, can save sky
Between, load inertia is small, and sewing speed is fast, and energy consumption is small；Stator or rotor can be as the independent parts of sewing machine, and temperature rise is small,
