Description
Technical Field
The invention belongs to the technical field of motors, and particularly relates to a permanent magnet linear motor with oriented silicon steel sheets laminated in a grading manner.
Background
The near-pole slot permanent magnet linear motor has the characteristics of high thrust, low loss, small electrical time constant, high response speed and the like, and is widely applied to the direct driving fields of high-precision high-speed numerical control machine tools, industrial robots and the like. The linear motor is directly driven to realize linear motion without any intermediate conversion mechanism, so that the linear motor has the advantages of reduced operation noise, unlimited operation, convenient installation, no contact, no abrasion, simple maintenance and the like, and is superior to a rotary motor and roller screw mode in terms of precision, rigidity, service life and other performance indexes. In the application of the direct drive field, the thrust density is a primary index of the linear motor, and how to improve the thrust density of the linear motor is a research hot spot problem of vast linear motor researchers in recent years.
Disclosure of Invention
The invention mainly aims at the magnetic circuit characteristics of the near-pole slot permanent magnet linear motor, sets the rolling direction of the oriented silicon steel sheet to be consistent with the magnetic circuit direction of the motor, and adopts a structure with separated tooth parts and yoke parts to realize the requirement. Then, the lamination mode of grading lamination is adopted to realize the lamination of the tooth part and the yoke part and the purpose of reducing the vibration noise of the motor.
The technical scheme is as follows:
the permanent magnet linear motor comprises a primary iron core 1, a primary winding coil 2, a secondary magnetic pole 4 and a secondary yoke part 5; the primary winding coil 2 is disposed between the primary teeth 6 of the primary core 1; the secondary pole 4 is provided on the secondary yoke 5, and an air gap 3 is formed between the secondary pole 4 and the primary core 1.
The tooth part and the yoke part of the primary iron core are designed by the oriented silicon steel sheet grading laminated permanent magnet linear motor, so that the direction of the whole magnetic circuit almost passes through the rolling direction of the oriented silicon steel sheet, namely, the rolling directions of the oriented silicon steel sheet are respectively ensured to be A and B, thereby realizing that the magnetic circuit direction of the yoke part is consistent with the rolling direction of the oriented silicon steel sheet, and the magnetic circuit direction of the tooth part is also consistent with the rolling direction of the oriented silicon steel sheet. The magnetic circuit of the oriented silicon steel sheet graded laminated permanent magnet linear motor is characterized in that magnetic circuit main magnetic flux D of the oriented silicon steel sheet graded laminated permanent magnet linear motor starts from one secondary magnetic pole, passes through an air gap to enter a primary tooth part, then bypasses a primary winding through a primary yoke part, and returns to two anisotropic magnetized magnetic poles adjacent to the primary magnetic pole through two adjacent teeth on two sides, so that the magnetic circuit direction of the main magnetic flux is always consistent with the rolling direction of the oriented silicon steel sheet with high magnetic permeability through the design of the slicing structure.
On the other hand, when the tooth magnetic path direction B is consistent with the rolling direction of the oriented silicon steel sheet, the tooth tip magnetic leakage magnetic path E is naturally ensured to be perpendicular to the rolling direction of the oriented silicon steel sheet, and the tooth tip magnetic leakage magnetic path E is consistent with the rolling direction of the oriented silicon steel sheet because the tooth tip magnetic leakage direction is perpendicular to the tooth magnetic path direction and the magnetic permeability of the oriented silicon steel sheet is high in magnetic permeability in the rolling direction and low in magnetic permeability perpendicular to the rolling direction, so that the tooth tip magnetic leakage magnetic path E is consistent with the rolling direction of the oriented silicon steel sheet, and the tooth tip magnetic leakage of the motor is inhibited.
The same can be said that the primary end leakage magnetic circuit F also passes through the rolling direction perpendicular to the oriented silicon steel sheet, so that the structure has a certain inhibiting effect on primary end leakage.
The primary iron core of the oriented silicon steel sheet grading lamination permanent magnet linear motor adopts a grading lamination mode, the traditional single-tooth assembly mode mainly adopts a dovetail groove mode and the like, the vibration noise is large, the structure adopts a grading lamination mode, the vibration noise is reduced to a certain extent, and the grading lamination mode is formed by clamping epoxy glass cloth plates 7 with the same size as the primary iron core 1 by matching rivets 8. The epoxy glass cloth plate 7 with the same size as the primary iron core 1 is clamped by matching rivets 8; the mounting mode is that an epoxy glass cloth plate 7 at one side is placed at the lowest part and then sequentially laminated, namely, a first-stage primary yoke part 9 is placed above a clamping plate, the top of a first-stage primary tooth part 10 corresponding to the first-stage primary yoke part 9 is embedded into a groove of the first-stage primary yoke part 9, a second-stage primary yoke part 11 is placed above 9, and a corresponding second-stage primary tooth part 12 is embedded into the groove of the second-stage primary yoke part 11; placing the tertiary primary yoke 13 above the first gear 11, and embedding the corresponding tertiary primary teeth 14 into the grooves of the tertiary primary yoke 13; by analogy, the two layers are sequentially and circularly laminated, and finally a clamping plate 7 made of the epoxy glass cloth plate on the other side is covered at the uppermost part, and the primary iron core is formed into a whole by using rivets 8.
The permanent magnet linear motor with the oriented silicon steel sheets is laminated in a grading manner, the magnetic circuit characteristics of the oriented silicon steel sheets are fully exerted, and the problem that special attention is required in electromagnetic parameter selection is also caused. The method is characterized by comprising the following steps:
1. the induced electromotive force constant of the linear motor with the oriented silicon steel sheet is higher than that of the linear motor with the unoriented silicon steel sheet, and the conventional linear motor needs to pay attention to verification of the induced electromotive force and the terminal voltage. For a linear motor for servo driving, attention is paid to the design of the induced electromotive force and the terminal voltage margin, and if the linear motor is designed according to the empirical value of the induced electromotive force constant of a non-oriented silicon steel sheet motor, the induced electromotive force and the terminal voltage may be too close to each other, so that the quick response capability of the servo driving motor cannot be realized.
2. When the permanent magnet linear motor with the oriented silicon steel sheet near-pole slot is designed, the magnetism density of the idle tooth part is close to the knee point of the oriented silicon steel sheet, the common oriented silicon steel sheet is generally about 1.8T-1.9T, and specific numerical values are determined by referring to the model of the silicon steel sheet.
3. The oriented silicon steel sheet is adopted as a primary material of the near-pole groove permanent magnet linear motor, and the influence of the thickness of the permanent magnet on the thrust density is not obvious enough. Therefore, the height of the permanent magnet pole is optimized through simulation results, so that the cost of the motor is effectively controlled.
The invention has the advantages that:
the permanent magnet linear motor is characterized in that the tooth part and the yoke part are separated, the magnetic circuit direction is kept consistent with the rolling direction of the oriented silicon steel sheet, and the magnetic conductivity of the oriented silicon steel sheet in the rolling direction is better than that of the unoriented silicon steel sheet, so that the saturation working point can be increased, magnetomotive force generated by the same primary current is increased, the magnetic flux density of the primary tooth part and the magnetic flux density of an air gap are increased, and the aim of increasing the thrust density of the motor in unit volume is fulfilled; the magnetic permeability of the oriented silicon steel sheet perpendicular to the rolling direction is low, and the magnetic leakage of the tooth tops and the magnetic leakage of the primary ends are inhibited, so that the cogging thrust fluctuation and the primary end positioning force of the motor are reduced. In addition, the connection between the tooth part and the yoke part adopts a grading lamination mode, and compared with a single tooth assembly mode using a dovetail groove and the like, the vibration noise is lower.

The tooth part and the yoke part of the primary iron core are separated, so that the direction of the whole magnetic circuit almost passes through the rolling direction of the oriented silicon steel sheet, namely, the rolling directions of the oriented silicon steel sheet are respectively ensured to be A and B, thereby realizing that the magnetic circuit direction of the yoke part is consistent with the rolling direction of the oriented silicon steel sheet, and the magnetic circuit direction of the tooth part is also consistent with the rolling direction of the oriented silicon steel sheet. C is the lamination direction of the primary core.
The magnetic circuit main magnetic flux D of the permanent magnet linear motor with the oriented silicon steel sheets laminated in a grading way starts from one secondary magnetic pole, passes through an air gap to enter a primary tooth part, bypasses a primary winding through a primary yoke part, and returns to two opposite magnetizing magnetic poles adjacent to the original magnetic pole through adjacent teeth on two sides; the main magnetic flux magnetic path direction is consistent with the rolling direction of the oriented silicon steel sheet with high magnetic permeability all the time.
The tooth tip magnetic leakage magnetic circuit direction E and the primary end magnetic leakage magnetic circuit direction F pass through the shearing direction of the oriented silicon steel sheet, namely are perpendicular to the rolling direction; the magnetic permeability of the oriented silicon steel sheet is high in the rolling direction and low in the shearing direction, so that the structure has a certain inhibition effect on tooth tip magnetic leakage and primary end magnetic leakage.
The manufacturing method of the permanent magnet linear motor with the oriented silicon steel sheets in a grading lamination mode is characterized in that a primary iron core is formed by clamping epoxy glass cloth plates 7 with the same size as the primary iron core 1 by matching rivets 8; the mounting mode is that an epoxy glass cloth plate 7 at one side is placed at the lowest part and then sequentially laminated, namely, a first-stage primary yoke part 9 is placed above a clamping plate, the top of a first-stage primary tooth part 10 corresponding to the first-stage primary yoke part 9 is embedded into a groove of the first-stage primary yoke part 9, a second-stage primary yoke part 11 is placed above 9, and a corresponding second-stage primary tooth part 12 is embedded into the groove of the second-stage primary yoke part 11; placing the tertiary primary yoke 13 above the first gear 11, and embedding the corresponding tertiary primary teeth 14 into the grooves of the tertiary primary yoke 13; by analogy, the two layers are sequentially and circularly laminated, and finally a clamping plate 7 made of the epoxy glass cloth plate on the other side is covered at the uppermost part, and the primary iron core is formed into a whole by using rivets 8. The grading level is related to the yoke height and motor vibration noise performance requirements, and the stacking mode is smaller than the traditional single-tooth assembling mode in vibration noise.
The stacking direction of the primary iron core of the permanent magnet linear motor with the oriented silicon steel sheets in a grading manner is shown in fig. 2, wherein A is the rolling direction of the oriented silicon steel sheets at the yoke part, B is the rolling direction of the oriented silicon steel sheets at the tooth part, and C is the stacking direction.

The yoke parts are respectively 11 and 13 of three different specifications, and the tooth parts are respectively 10, 12 and 14 of three different specifications. 7. The specific implementation process of the components 8, 9, 10, 11, 12, 13 and 14 is divided into the following steps that the epoxy glass cloth plate 7 at one side is placed at the lowest part, and then laminated in sequence, namely, the first-stage primary yoke 9 is placed above a clamping plate, the top of the first-stage primary tooth 10 corresponding to the first-stage primary yoke 9 is embedded into a groove of the first-stage primary yoke 9, the second-stage primary yoke 11 is placed above 9, and the corresponding second-stage primary tooth 12 is embedded into the groove of the second-stage primary yoke 11; placing the tertiary primary yoke 13 above the first gear 11, and embedding the corresponding tertiary primary teeth 14 into the grooves of the tertiary primary yoke 13; by analogy, the two layers are sequentially and circularly laminated, and finally a clamping plate 7 made of the epoxy glass cloth plate on the other side is covered at the uppermost part, and the primary iron core is formed into a whole by using rivets 8.
