According to the rotor structure of the permanent magnet iron-core-free motor, the assembled motor is small in axial size, low in motor operating noise and high in work efficiency.
Description
Technical field
The invention belongs to permanent magnetic brushless field, particularly relate to a kind of rotor of permanent magnet iron coreless motor and the mounting structure of stator.
Background technology
At present, operationally, the efficiency of electrified wire effective cutting magnetic field in rotor field is not high for existing iron core motor; Because winding is cored, produce magnetic hysteresis loss and eddy current loss and residual loss in electric machine rotation process, cause electric motor starting electric current comparatively large, the low energy-saving effect of efficiency is poor.By motor structural limitations, bulking value is comparatively large, consumes a large amount of silicon steel sheet.
Summary of the invention
In order to solve the problems of the prior art, the object of this invention is to provide a kind of rotor of permanent magnet iron coreless motor and the mounting structure of stator.
In order to realize technique scheme, the present invention adopts technical scheme as described below:
The rotor of permanent magnet iron coreless motor and a mounting structure for stator, it comprises rotor and stator, and described stator is made up of the armature winding dish of iron-core-free structure, and described rotor is made up of the yoke that two are provided with some magnets; Two yokes and armature winding dish are disk-like structure, and two yokes lay respectively at the arranged on left and right sides of armature winding dish on main shaft, and two yokes are parallel with the card of armature winding dish, and in the air gap between armature winding dish and the yoke of its both sides, magnetic density is equal; On the magnet that magnet in two yokes is relative, adjacent one by one each other, pole polarity is contrary, forms axial magnetic field between the magnet in two yokes, and the some magnets in each yoke to be arranged in yoke according to N pole, S pole are alternately uniform and surround circle.
Further, described stator is superposed by the single-phase winding dish of ground floor single-phase winding dish, the second layer single-phase winding dish and third layer to connect to form, and three layers of single-phase winding dish adopt star connection.
Further, described magnet is sector structure.
Owing to adopting technique scheme, the present invention has following superiority:
What the present invention was formed is axial magnetic field, thus reduces the axial dimension of motor, reduces the weight of motor, the occasion making motor be applicable to bulk to be restricted; Stator adopts iron-core-free structure, and eliminate the magnetic hysteresis loss of the magnetic material that cogging torque and iron core bring, eddy current loss and residual loss, therefore, this motor rotation noise is little, and operating efficiency is high.
