specific Embodiment approach 1

[0007] Specific Embodiment 1: Refer to FIG. 1 to illustrate this embodiment. A two-sided flat three-phase linear permanent magnet synchronous motor of this embodiment is composed of a casing 5, an armature component and a permanent magnet excitation component, the casing 5 is made of a magnetically conductive material, and the permanent magnet excitation Parts are made up of two groups of flat permanent magnets 3, the number of poles formed by the permanent magnets 3 is P=2k, and the two groups of flat permanent magnets 3 are respectively fixed on the two-sided flat casing 5, and the two groups of permanent magnets The magnetization directions of the permanent magnets on the corresponding positions of the magnets 3 are opposite, that is, the polarities of the directions facing the armature components are the same, and the magnetization directions of adjacent permanent magnets 3 in the same group of permanent magnets are opposite, and the armature components are composed of arma...

specific Embodiment approach 2

[0009] Specific Embodiment 2: Refer to FIG. 2 to illustrate this embodiment. The difference between this embodiment and the two-sided flat three-phase linear permanent magnet synchronous motor described in Embodiment 1 is that the permanent magnet excitation part also includes a flat permanent magnet yoke 4, and the permanent magnet yoke 4 is fixed between the permanent magnet 3 and the casing 5, and the casing 5 in this embodiment may be made of non-magnetic materials.

specific Embodiment approach 3

[0010] Specific Embodiment Three: Refer to FIG. 3 and FIG. 4 to illustrate this embodiment. The difference between this embodiment and the two-sided flat three-phase linear permanent magnet synchronous motor described in the second embodiment is that the permanent magnet 3 is embedded in the permanent magnet yoke 4 and arranged at intervals with the permanent magnet yoke, so The permanent magnets 3 are magnetized in parallel, the magnetization direction is parallel to the direction of motion, the magnetization direction of the adjacent permanent magnets 3 is opposite, and the magnetization directions of the permanent magnets at the corresponding positions of the two sets of permanent magnets 3 respectively fixed on the double-sided casing 5 same.

[0011] When the casing 5 of the double-sided flat motor of this embodiment is made of magnetically permeable material, a layer of magnetic isolation plate 6 is added between the casing 5 and the permanent magnet 3 and the permanent ...

Abstract

A kind of two-sized flat three phase beeline permasyn motor, it relates to field of motor. Aiming at resolve problem that pitch Taut and polar distance Taup design is not easy to give attention to, every ends are across with each other, ends of coil is long, the copper cost is big, insulation of coil is complex, cost of manufacture is high of current flat three phase beeline permasyn motor, the invention designs a kind of two-sized flat three phase beeline permasyn motor. The invention includes armature part and permanent-magnet excitation parts; the armature part is nipped between the permanent-magnet excitation parts which are parallel with each other, two gases are between the armature part and two permanent-magnet excitation parts, thereinto the armature part mainly composes armature winding and armature iron core; the permanent-magnet excitation parts composes permanent-magnet. Iron core pitch Taut of the armature and polar distance Taup of the permanent-magnet fulfills the relation 3nTaut=(3n+-1)Taup, thereinto n is natural number. The beeline motor of the invention can be used as beeline motor, but also as the beeline generator, it possesses wide application foreground.

Description

technical field [0001] The invention relates to the field of motors, in particular to a flat three-phase linear permanent magnet synchronous motor. Background technique [0002] The armature core pitch τ of the traditional flat three-phase linear permanent magnet synchronous motor t The pole distance τ from the permanent magnet p Satisfy the relation 3τ t =τ p , this structure is called an integer tooth structure, that is, the number of teeth of each pole and each phase of the motor is an integer. The main problem of the integer tooth structure linear permanent magnet synchronous motor is: on the one hand, the positioning force of the motor caused by the tooth effect is relatively large; On the other hand, the performance-to-volume ratio of the motor is low, which is mainly due to the fact that when the pole pitch τ of the motor p When the design is large, the yoke part of the permanent magnet will be thickened, which will increase the volume and weight of the motor, and...
