Detailed Description
The present application will be described in detail below with reference to embodiments shown in the drawings. The embodiments are not limited to the embodiments, and structural, methodological, or functional changes made by those skilled in the art according to the embodiments are included in the scope of the present disclosure.
A linear motor is a transmission device that directly converts electric energy into linear motion mechanical energy without any intermediate conversion mechanism. The rotating motor can be seen as being formed by cutting a rotating motor in a radial direction and spreading the rotating motor into a plane. The side evolved from the stator is still referred to as the stator and the side evolved from the rotor is referred to as the mover.
Through years of development, linear motors have been developed for a long time and are widely used. With the application and popularization of linear motors, the requirements of customers on the motors are higher and higher. When the linear motor is applied to the occasions with ultra-high acceleration and ultra-short positioning time, the linear motor needs to be matched with a driver for use, and the existing driver in the market can not provide larger peak thrust because the motor cannot provide enough current, so that the acceleration and the positioning time of the motion are influenced, and the overall performance of the motor is influenced.
Meanwhile, in some application occasions requiring frequent acceleration and deceleration, when the time occupied by acceleration and deceleration in the whole movement process is longer and even exceeds the time of uniform movement, the motor wire is easy to generate heat abnormally and the motor is damaged in an accelerated manner. In order to overcome the problem, a larger-size motor is often required to be selected, so that waste is caused.
In order to solve the above problems, the applicant has developed a multi-drive linear motor which is provided with two or more winding groups 101, and can be separately driven and controlled according to application requirements, thereby matching the requirements of different application scenarios.
Specifically, please refer to fig. 1 and 2, wherein fig. 1 is a schematic structural diagram of an embodiment of a motor mover of the multi-drive linear motor of the present application with a top plate removed, and fig. 2 is a schematic structural diagram of an embodiment of a motor stator of the multi-drive linear motor of the present application.
The linear motor comprises a motor rotor 10 and a motor stator 20, wherein the motor rotor 10 comprises three rows of winding groups 101 which are arranged in parallel, and each row of winding group 101 comprises a plurality of magnetic steels 1011 which are uniformly arranged at intervals along a first direction x and windings 1012 which are wound on the magnetic steels 1011.
The electric rotor is further connected with at least two power lines 30, wherein one power line 30 is electrically connected with one winding set 101, and the other power line 30 is electrically connected with the other two winding sets 101.
The motor stator 20 extends along the first direction x, and the motor stator 20 is configured to cooperate with the motor mover 10 to drive the motor mover 10 to move along the first direction x.
Specifically, the motor stator 20 includes a magnet group 201 extending along the first direction x, and the magnet group 201 includes N-pole permanent magnets 2011 and S-pole permanent magnets 2012 arranged at staggered intervals.
The motor mover 10 can be driven to rapidly move linearly along the first direction x in which the motor stator 20 extends by the magnetic fields of the magnet groups 201 arranged at staggered intervals and the current variation of the winding group 101 of the motor mover 10.
In the embodiment, the motor stator 20 includes three rows of magnet groups 201 arranged in parallel at intervals, and each magnet group 201 is capable of cooperating with one winding group 101 to drive the motor mover 10 to move along the first direction.
In other embodiments, the motor stator 20 may also include only another number of magnet groups 201 extending along the first direction, so as to ensure that all the winding groups 101 of the motor mover 10 can be subjected to the magnetic field of the electronic stator, i.e., the beneficial effects of the present embodiment may be achieved.
It can be understood that the working state of the winding group 101 can be controlled by the two power lines 30, and the two power lines 30 can be driven in the same direction or in the opposite direction or in a single direction, so that three working states of the single winding group 101, the two winding groups 101 and the three winding groups 101 are realized, and the requirements of different application scenes are met. The common same-direction driving means that the driving directions of the two power lines 30 are the same, and the driving directions of the corresponding three winding groups 101 are the same; the common reverse driving means that the driving directions of the two power wires 30 are opposite, and the driving directions of the two winding sets 101 connected with one power wire 30 are opposite to the driving directions of the winding sets 101 connected with the other power wire 30.
Referring to fig. 3 and 4, fig. 3 is an exploded structure schematic diagram of an embodiment of a motor mover of the multi-drive linear motor of the present application, and fig. 4 is a structure schematic diagram of an embodiment of a magnetic steel unit of the multi-drive linear motor of the present application.
In order to ensure the stability of the mounting structure of the multiple winding groups 101 and avoid the offset phenomenon in the high-speed movement process, in the embodiment, three magnetic steels 1011 located on the same plane perpendicular to the first direction x in the three winding groups 101 are connected to form a magnetic steel unit 102.
Specifically, as shown in fig. 4, magnetic steel unit 102 includes a mounting plate 1021 and three magnetic steels 1011. The mounting plate 1021 comprises a first surface, and the mounting plate 1021 extends along the second direction y; the three magnetic steels 1011 are uniformly arranged on the first surface of the mounting plate 1021 at intervals along the second direction y; wherein the second direction y is a direction perpendicular to the first direction x on the first surface.

In order to avoid the threading hole 1051 from causing the inside of the electric mover to be affected by the external environment, a waterproof joint 1052 for connecting with the power line 30 is arranged at the threading hole 1051.
The mounting plate 1021 is disposed between the pair of end plates 104. Specifically, a sliding groove 1041 extending along the first direction is formed in one side surface of the end plate 104 close to the bottom plate 103, a sliding block 1022 matched with the sliding groove 1041 is arranged at an end portion of the mounting plate 1021, and two ends of the mounting plate 1021 are respectively inserted into the sliding groove 1041 at the corresponding end through the sliding block 1022.
As can be appreciated, the mounting plate 1021 slides along the sliding slot 1041 through the sliding block 1022, so as to realize the quick mounting of the magnetic steel unit 102, and facilitate the dismounting and maintenance of the structure.
In order to effectively improve the utilization rate of the internal space of the motor rotor 10, the chute 1041 is disposed on the side of the end plate 104 close to the base plate 103.
The number of the winding groups 101 of the electric mover is not limited, and the above embodiments only show that the motor mover 10 includes three winding groups 101, and in other embodiments, the motor mover 10 further includes other numbers of winding groups 101, which can be adjusted according to specific working conditions, for example, the motor mover 10 may include 5 winding groups 101 and is connected to three power lines 30, one of the power lines 30 is connected to one winding group 101, and the other two power lines 30 are respectively connected to two winding groups 101, which can both achieve the effect of the present embodiment.
