Abstract
The utility model discloses a kind of Halbach type array permanent magnetism non-gullet motors, it is characterized by comprising stator cores and rotor fixed plate, the stator core is anodontia groove structure design, it is arranged with slotless stator coil on the stator core, is equipped with the permanent magnet of Halbach type array composition in the fixed plate towards stator core side.This practical application for having the advantages that the series of advantages such as no torque ripple, light-weight, high-efficient, being suitble to some requirements more special, particularly suitable for wind-force, hydroelectric generation and wind-light complementary system；It more can be used for the Electric Traction or automobile-used of low rotation speed large torque.
Description
Technical field
The utility model relates to technical field of motors, in particular to a kind of Halbach type array permanent magnetism non-gullet motors.
Background technique
Single tray type structure is the structure occurred early stage, and structure is simple, but there is also the unbalanced problems of axial force, need
Carefully to design bearing arrangement.Their torque density is not very greatly that application is not especially more.Center roller structure is band
The rotor disk of magnet steel, is mounted on middle, and stator ferrite core is arranged in both ends.Motor just has two air gaps in this way, not only turns
Square density rises, and rotor disk can be cancelled out each other by the magnetic pull of left and right sides iron core, so just solve
The problem of uneven axial force.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technical problem, provides a kind of high efficiency, energy conservation, multi-purpose
The Halbach type array permanent magnetism non-gullet motor on way.
In order to solve the above technical problems, technical solution provided by the utility model be a kind of Halbach type array permanent magnetism without
Tooth socket motor, it is characterised in that: including stator core and rotor fixed plate, the stator core is anodontia groove structure design, institute
It states and is arranged with slotless stator coil on stator core, be equipped with Halbach type towards stator core side in the fixed plate
The permanent magnet of array composition.
Preferably, the stator core and rotor fixed plate are disc, and equity is placed in motor, can be attempted
Generate axial air-gap field.
Preferably, the permanent magnet is mutually fixed by magnet adhesive special with rotor fixed plate, in space radially
Distribution.
Preferably, the slotless stator coil is the disk as made of reinforcing fiber resin encapsulating.
The utility model has the advantages that no torque ripple, light-weight, high-efficient etc. are a series of compared with prior art
Advantage, the application for being suitble to some requirements more special, particularly suitable for wind-force, hydroelectric generation and wind-light complementary system；
It more can be used for the Electric Traction or automobile-used of low rotation speed large torque.
Detailed description of the invention
Fig. 1 is a kind of Halbach type array permanent magnetism non-gullet motor structural schematic diagram of the utility model.
It is as shown in the figure: 1, stator core, 2, rotor fixed plate, 3, slotless stator coil, 4, permanent magnet.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of Halbach type array permanent magnetism non-gullet motor, it is characterised in that: including stator core 1 and turn
Sub- fixed plate 2, the stator core 1 are anodontia groove structure design, are arranged with slotless stator coil 3 on the stator core 1,
The permanent magnet 4 of Halbach type array composition is equipped in the fixed plate 2 towards 1 side of stator core.
The stator core 1 and rotor fixed plate 2 are disc, and equity is placed in motor.
The permanent magnet 4 is fixed by magnet adhesive special and 2 phase of rotor fixed plate.
The slotless stator coil 3 is the disk as made of reinforcing fiber resin encapsulating.
The common NS arrangement of magnet is changed to Halbach array by the utility model, conventional iron core slot is removed, in this way
Magnet dosage can not only be reduced, the anodontia effect of grooves, efficiency also can be improved, and vibrate, noise substantially reduces and compact-sized,
Can also polydisc combination and realize different power, coil unit is identical.Using possessing the permanent-magnet material of high-coercive force as magnetic
Pole, and common arrangement mode is replaced using Halbach type array, iron core is manufactured by the way of not tooth punching into Halbach type
Array gearless motor, this structure can obtain higher because there is magnet accumulating cap that the dosage sine of magnet can be greatly reduced
Air gap flux density and power density, efficiency can greatly improve and motor is made to possess better electromagnetic performance and electric property.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
