Description
Technical field
The present invention relates to technical field of motors, specifically a kind of novel permanent magnetic synchronous motor structure.
Background technique
Both permanent magnet synchronous motor collection alternating current generator and direct current generator better than one, and volume can be readily implemented
Small, operational efficiency is high, and power density is big, and system is stablized, and is just increasingly obtaining in the numerous areas of industrial development and daily life
It is widely applied.But traditional magneto, output torque is small, and loss will appear leakage field greatly and at the inner surface of rotor
Phenomenon, these disadvantages will limit the development of permanent magnet synchronous motor.
Summary of the invention
It is an object of the present invention to provide a kind of novel permanent magnetic synchronous motor structures, are turned with solving existing permanent magnet synchronous motor output
Square is small and rotor inner surface at the problem of will appear magnetic flux leakage.
In order to achieve the above objectives the technical scheme adopted by the invention is that: a kind of novel permanent magnetic synchronous motor structure, it is special
Sign is that motor body includes stator, adjustable magnetic iron block, rotor, permanent magnet；The adjustable magnetic iron block is combined with motor stator to be made
It becomes stator tooth, magnetic bridge between using between the rotor and armature spindle, and the rotor uses permanent magnet tangential on board
Formula rotor.
In above-mentioned technical proposal, the adjustable magnetic iron block is combined with motor stator becomes stator tooth.
In above-mentioned technical proposal, magnetic bridge between being used between the rotor and armature spindle.
In above-mentioned technical proposal, the rotor uses permanent magnet tangential on board formula rotor.
By using above-mentioned technical proposal, permanent magnet synchronous motor obtains good operation characteristic, increases adjustable magnetic in motor
Iron block makes traditional mechanical gear be converted into magnetic gear the vibration noise of motor is become smaller, and torque density is got higher, then will adjust
Magnet block combines with motor stator and becomes stator tooth, reduces one layer of air gap and simplifies electric machine structure；Rotor and rotor
Magnetic bridge between being used between axis so that introduced in leakage field circuit high magnetic resistance every magnetic air gap, the leakage magnetic flux of rotor inner radius can be with
Effectively inhibited；Rotor uses permanent magnet tangential on board formula rotor, so that the anti-demagnetization capability of magnet is become strong, torque output range
Become larger, facilitates weak magnetic control.
Detailed description of the invention
Attached drawing 1 is a kind of structural schematic diagram of permanent magnetic synchronous motor structure；
In figure: 1, stator, 2, winding, 3, adjustable magnetic iron block, 4, rotor, 5, permanent magnet, 6, magnetic bridge

Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Referring to Figure of description 1, a kind of novel permanent magnetic synchronous motor structure, which is characterized in that motor body include stator,
Adjustable magnetic iron block, rotor, permanent magnet；The stator uses low-loss silicon steel material, and the rotor uses solid rotor, institute
The permanent magnet tangential on board stated is in rotor.
The adjustable magnetic iron block is combined with motor stator becomes stator tooth.
Magnetic bridge between being used between the rotor and armature spindle.
The rotor uses permanent magnet tangential on board formula rotor.
By using above-mentioned technical proposal, permanent magnet synchronous motor obtains good operation characteristic, increases adjustable magnetic in motor
Iron block makes traditional mechanical gear be converted into magnetic gear the vibration noise of motor is become smaller, and torque density is got higher, then will adjust
Magnet block combines with motor stator and becomes stator tooth, reduces one layer of air gap and simplifies electric machine structure；Rotor and rotor
Magnetic bridge between being used between axis so that introduced in leakage field circuit high magnetic resistance every magnetic air gap, the leakage magnetic flux of rotor inner radius can be with
Effectively inhibited；Rotor uses permanent magnet tangential on board formula rotor, so that the anti-demagnetization capability of magnet is become strong, torque output range
Become larger, facilitates weak magnetic control.
This embodiment is just an exemplary description of this patent, does not limit its protection scope, those skilled in the art
Member can also be changed its part, as long as it does not exceed the essence of this patent, within the protection scope of the present patent.
