The present invention provides a linear motor 10, referring to fig. 1, 2, 6 and 7, the linear motor 10 includes a sliding mechanism 13, a primary mechanism 11 and a secondary mechanism 12; the sliding mechanism 13 includes a base 131 and a sliding seat 132 movably disposed on the base 131, and the primary mechanism 11 and the secondary mechanism 12 are disposed on the sliding mechanism 13 with a predetermined physical gap therebetween, so that the pushing force generated by the interaction between the primary mechanism 11 and the secondary mechanism 12 can push the primary mechanism 11 or the secondary mechanism 12 to move linearly. For example, the primary mechanism 11 is fixed to the base 131, the secondary mechanism 12 is fixed to the carriage 132, and the secondary mechanism 12 slides with respect to the primary mechanism 11; for another example, the primary mechanism 11 is fixed to the slider 132, the secondary mechanism 12 is fixed to the base 131, and the primary mechanism 11 slides relative to the secondary mechanism 12.
As shown in fig. 3 to 5, the secondary mechanism 12 includes at least a first secondary unit 121 and a second secondary unit 122 arranged along the moving direction of the slider 132, the first secondary unit 121 includes a first yoke 1212 and a first magnetic steel 1211 disposed on the first yoke 1212, the second secondary unit 122 includes a second yoke 1222 and a second magnetic steel 1221 disposed on the second yoke 1222, the first yoke 1212 and the second yoke 1222 have a major axis disposed along the moving direction of the slider 132 and a minor axis disposed perpendicular to the major axis, the first magnetic steel 1211 is inclined from the extending direction of the minor axis toward the moving direction of the slider 132 by a first angle, and the second magnetic steel 1221 is inclined from the extending direction of the minor axis away from the moving direction of the slider 132 by a second angle. Please refer to fig. 1, fig. 4, and fig. 6 for the directions of the major axis and the minor axis.
In the present invention, the secondary mechanism 12 includes at least the first secondary unit 121 and the second secondary unit 122 along the moving direction of the slider 132, the first yoke 1212 and the second yoke 1222 have a long axis disposed along the moving direction of the slider 132 and a short axis disposed perpendicular to the long axis, the first magnetic steel 1211 disposed on the first yoke 1212 is inclined by a first angle from the extending direction of the short axis toward the moving direction of the slider 132, so that a first bending moment is generated between the first secondary unit 121 and the primary mechanism 11, and the second magnetic steel 1221 disposed on the second yoke 1222 is tilted by a second angle from the extension direction of the short axis away from the moving direction of the slider 132, so that a second bending moment is generated between the second secondary unit 122 and the primary mechanism 11, therefore, the inclination direction of the first magnetic steel 1211 is opposite to the inclination direction of the second magnetic steel 1221, and the first bending moment and the second bending moment can be offset with each other in terms of the linear motor 10 as a whole. In the technical scheme, on one hand, thrust fluctuation generated between the primary mechanism 11 and the secondary mechanism 12 is reduced through the inclined first magnetic steel 1211 and the inclined second magnetic steel 1221, and the integral thrust of the linear motor 10 can be improved; on the other hand, the inclination direction of the first magnetic steel 1211 is opposite to that of the second magnetic steel 1221, so that the technical problem that the performance of the linear motor 10 is affected by bending moment generated between a rotor and a stator of the motor due to the inclination of the magnetic steel is solved.
Taking the primary mechanism 11 fixed on the base 132 and the secondary mechanism 12 fixed on the sliding seat 132 as an example, the electromagnetic thrust acting on the first secondary unit 121 is decomposed into a first component force in the same moving direction as the sliding seat 132 and a second component force perpendicular to the first magnetic steel 1211, and the first secondary unit 121 generates a first bending moment due to the second component force; the electromagnetic thrust acts on the second secondary unit 122 and is then decomposed into a third component force in the same direction as the moving direction of the slide carriage 132 and a fourth component force perpendicular to the second magnetic steel 1221, the second primary unit 112 generates a second bending moment due to the fourth component force, the inclination directions of the first magnetic steel 1211 and the second magnetic steel 1221 are opposite, so that the second component force and the fourth component force act in opposite directions, and the rotation directions of the first bending moment generated by the second component force and the second bending moment generated by the fourth component force are opposite, thereby achieving the effect of canceling the bending moment.
It should be noted that the secondary mechanism 12 includes at least a first secondary unit 121 and a second secondary unit 122 arranged along the moving direction of the sliding seat 132, then the secondary mechanism 12 is further configured to include a plurality of secondary units such as the first secondary unit 121, the second secondary unit 122, the third secondary unit, and the fourth secondary unit arranged along the moving direction of the sliding seat 132, and the inclination directions of the magnetic steels of any two secondary units are opposite to each other, so as to achieve the effect of canceling the bending moment. Meanwhile, the secondary mechanism 12 has an oblique pole, so that the thrust fluctuation of the motor in the operation process is reduced, and the positions of two or more secondary units are reasonably configured to further reduce the thrust fluctuation of the linear motor 10 in the operation process.
Preferably, the first angle is equal to the second angle, and a first angle at which the first magnetic steel 1211 inclines from the extension direction of the short shaft toward the moving direction of the slider 132 is equal to a second angle at which the second magnetic steel 1221 inclines from the extension direction of the short shaft away from the moving direction of the slider 132, as shown in fig. 4, the first angle is ≦ a, the second angle is ≦ b, and the magnitudes of ≦ a and ≦ b are equal, so that the magnitude of the first bending moment applied to the first magnetic steel 1211 is equal to the magnitude of the second bending moment applied to the second magnetic steel 1221, and the directions are opposite to each other, so that the first bending moment and the second bending moment can be almost completely cancelled.
The primary mechanism 11 includes an iron core 111 with a tooth slot 11a and a winding 112 disposed on the iron core 111. When the winding 112 is supplied with an ac power, the air gaps between the first secondary unit 121, the second secondary unit 122 and the primary mechanism 11 generate a traveling wave magnetic field, and the first secondary unit 121 and the second secondary unit 122 induce an electromotive force and generate a current under the cutting of the traveling wave magnetic field, and the current and the magnetic field in the air gaps act to generate an electromagnetic thrust. When the primary mechanism 11 is fixed, the electromagnetic thrust pushes the secondary mechanism 12 to move linearly; when the secondary mechanism 12 is fixed, the electromagnetic thrust pushes the primary mechanism 11 to move linearly.
In some specific embodiments, the base 131 includes a bottom wall 1311 and a side wall 1312 opposite to and spaced apart from the bottom wall 1311, and the sliding seat 132 is movably connected to an end of the side wall 1312 far from the bottom wall 1311. The primary mechanism 11 and the secondary mechanism 12 are located in a space formed by the base 131 and the slider 132, and perform relative linear movement by sliding provided on the slider 132 and the opposite side wall 1312.
In one embodiment, the sliding mechanism 13 further includes a guide rail 133 disposed between the side wall 1312 and the sliding seat 132, so that the sliding seat 132 can slide relative to the base 131 smoothly.
Referring to fig. 3, one end of the side wall 1312 away from the bottom wall 1311 is formed with a first guide groove 1312a in contact with the guide rail 133, and the slide 132 is formed with a second guide groove 132a in contact with the guide rail 133.
In some specific embodiments, the guide rail 133 is fixedly connected to the side wall 1312 through the first guide groove 1312a, so that the sliding seat 132 slides relative to the guide rail 133 through the second guide groove 132 a; or, the guide rail 133 is fixedly connected to the sliding base 132 through the second guide groove 132a, and the guide rail 133 slides on the side wall 1312 through the first guide groove 1312a to drive the sliding base 132 to move linearly.
In one embodiment, referring to fig. 1 and 2, the core 111 is disposed on the sliding base 132, the first yoke 1212 and the second yoke 1222 are disposed on the base 131, and specifically, the slot 11a of the core 111 faces the first magnetic steel 1211 disposed on the first yoke 1212 and the second magnetic steel 1221 disposed on the second yoke 1222. That is, the primary mechanism 11 is disposed on the slider 132 through the iron core 111, and the secondary mechanism 12 is disposed on the base 131 through the first yoke 1212 and the second yoke 1222; the secondary mechanism 12 is therefore fixed and the primary mechanism 11 moves linearly with the carriage 132 relative to the secondary mechanism 12 under thrust.
In one embodiment, referring to fig. 6 and 7, the core 111 is disposed on the bottom wall 1311, the first yoke 1212 and the second yoke 1222 are disposed on the slider 132, and specifically, the slot 11a of the core 111 faces the first magnetic steel 1211 disposed on the first yoke 1212 and the second magnetic steel 1221 disposed on the second yoke 1222. That is, the primary mechanism 11 is disposed on the base 131 through the iron core 111, and the secondary mechanism 12 is disposed on the slider 132 through the first yoke 1212 and the second yoke 1222; thus, the primary mechanism 11 is fixed, and the secondary mechanism 12 moves linearly with the carriage 132 relative to the primary mechanism 11 under thrust.
Referring to fig. 5, preferably, the first yoke 1212 and the second yoke 1222 are spaced apart from each other, and a distance between the first yoke 1212 and the second yoke 1222 is adjustable according to actual needs, so as to prevent the first secondary unit 121 and the second secondary unit 122 from abutting against each other due to bending moment.
The linear motor 10 further includes a scale 141 provided on the bottom wall 1311 and a scale reading head 142 provided on the carriage 132 opposite the scale 141. When the linear scale reading head 142 moves linearly along with the carriage 132, the linear scale reading head 142 also moves on the linear scale 141 in synchronization, so that the relative displacement between the primary mechanism 11 and the secondary mechanism 12 is detected, and the linear motion of the linear motor 10 is controlled.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
