Abstract
The utility model discloses a kind of rotor structure of permanent magnet iron coreless motor, it comprises the yoke that two are provided with some magnets, two yokes are the disk-like structure which is provided with centre bore, the card of two yokes is parallel to each other, on the magnet that magnet in two yokes is relative, adjacent one by one each other, pole polarity is contrary, form axial magnetic field between magnet in two yokes, the some magnets in each yoke to be arranged in yoke according to N pole, S pole are alternately uniform and surround circle.Adopt the motor that the utility model is assembled into, axial dimension is little, and motor rotation noise is little, and operating efficiency is high.
Description
Technical field
The utility model belongs to permanent magnetic brushless field, particularly relates to a kind of rotor structure of permanent magnet iron coreless motor.
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 purpose of this utility model is to provide a kind of rotor structure of permanent magnet iron coreless motor.
In order to realize technique scheme, the utility model adopts technical scheme as described below:
A kind of rotor structure of permanent magnet iron coreless motor, it comprises the yoke that two are provided with some magnets, two yokes are the disk-like structure which is provided with centre bore, the card of two yokes is parallel to each other, on the magnet that magnet in two yokes is relative, adjacent one by one each other, pole polarity is contrary, form axial magnetic field between magnet in two yokes, 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 magnet is sector structure.
Owing to adopting technique scheme, the utility model has following superiority:
When assembling motor, two yokes are sleeved on main shaft, and the stator of an iron-core-free structure to be arranged on main shaft and between two yokes, owing to forming axial magnetic field between two yokes, electrified wire perpendicular cuts magnetic induction line in rotor field can make motor rotation noise little, and operating efficiency is high; In addition, this rotor structure can make the motor after assembling be axial stacked structure and stator iron-core-free, thus reduces the axial dimension of motor, reduces the weight of motor, the occasion making motor be applicable to bulk to be restricted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-yoke; 2-magnet; 3-main shaft.
Embodiment
As shown in Figure 1, a kind of rotor structure of permanent magnet iron coreless motor, it comprises the yoke 1 that two are provided with some magnets 2, two yokes 1 are the disk-like structure which is provided with centre bore, the card of two yokes is parallel to each other, on the magnet 2 that magnet in two yokes is relative, adjacent one by one each other, pole polarity is contrary, forms axial magnetic field between the magnet 2 in two yokes 1, and the some magnets in each yoke 1 to be arranged in yoke according to N pole, S pole are alternately uniform and surround circle.
When adopting rotor structure assembling motor of the present utility model, two yokes are sleeved on main shaft 3, and the stator of an iron-core-free structure to be arranged on main shaft and between two yokes, owing to forming axial magnetic field between two yokes, electrified wire perpendicular cuts magnetic induction line in rotor field can make motor rotation noise little, and operating efficiency is high; In addition, this rotor structure can make the motor after assembling be axial stacked structure and stator iron-core-free, thus reduces the axial dimension of motor, reduces the weight of motor, the occasion making motor be applicable to bulk to be restricted.
