Description

Technical area

[0001] The utility model relates to the technical field of electric motors and in particular to a high-speed, short-distance, multi-track reciprocating array electric motor. Background technology

[0002] Low efficiency of conventional motors: In short-distance and fast round-trip motion scenarios, conventional rotating motors must be converted to linear motion through complex transmission mechanisms, resulting in high energy loss and low efficiency.

[0003] High cost of the linear motor: The existing linear motor has a complex structure and high manufacturing costs, and it is difficult to achieve a movement with multiple trajectories.

[0004] Limited application of miniaturization: In miniaturized devices (e.g., robot joints, artificial hearts), conventional drives are bulky and energy-intensive, making it difficult to meet the demand.

[0005] Therefore, a high-speed, short-range, multi-track reciprocating array electric motor has become an urgent problem to be solved. Contents of the utility model

[0006] The technical problem addressed by this utility model is to abandon the rotor structure of the conventional motor and instead utilize the interaction between multiple groups of magnets and coils to achieve reciprocating motion over short distances, at high speed, and across multiple tracks. The device is particularly suitable for applications requiring precise control and rapid response, such as robot dynamics, facial expression simulation, artificial heart drives, vibration devices, aircraft wing retraction, and boat paddling.

[0007] To solve the aforementioned technical problems, the utility model offers the following technical solution: a high-speed, short-range, multi-track reciprocating array electric motor comprising a magnet, a rectangular coil, a guide rail, a power-bearing terminal end, a base, and a support frame.

[0008] The magnets are arranged in several groups and distributed along the front and back of the guide rail. Adjacent magnets have the same polarity, and the front end of the first group of magnets is firmly connected to the base.

[0009] The rectangular coil is located inside the magnet, and each group of rectangular coils forms an integral force carrier body through a group of supporting frames. The front end edge of the rectangular coil is located in the magnetic field of one magnet, and the opposite rear end edge is located in the magnetic field of the adjacent magnet (the rear edge can also be rigidly connected to the front of the adjacent magnet without electromagnetic contact).

[0010] The load-bearing connection end is firmly connected to the rear end edge of the last set of rectangular coils.

[0011] Furthermore, the magnet is either a permanent magnet or an electromagnet.

[0012] Furthermore, the rectangular coil consists of a copper coil or an aluminum coil.

[0013] Furthermore, the support frame is made of a hard, non-conductive and lightweight material.

[0014] Furthermore, the power-bearing connection end includes a mechanical arm, a piston and a vibration head.

[0015] Furthermore, the guide rails are made of hard and lightweight materials and are provided in two or more groups, an upper and a lower one.

[0016] Or the guide rail is made of soft and tough material and is completely encased in a tube-like form.

[0017] The necessary lubrication is ensured between the guide rail and the magnet.

[0018] Furthermore, each rectangular coil is equipped with a positive and a negative terminal, which are connected to a power source.

[0019] The advantages of the utility model over the prior art are: Efficient energy conversion: Through the coordinated work of several sets of magnets and coils, an efficient conversion of electrical energy into mechanical energy is achieved, and energy utilization is significantly improved.

[0020] Fast response: Several groups of magnets and coils react simultaneously with a fast response rate, and a large distance movement can be achieved in a short time, which is suitable for high-speed movement scenarios (e.g., telescoping aircraft wings).

[0021] Precise control: By controlling the direction of the current or the direction of the magnetic field, the precise movement of the stressed end of the clamp can be achieved to meet the requirements of high-precision applications.

[0022] Multi-track movement: Suitable for complex motion path scenarios, such as robot joints, facial expression simulation, etc.

[0023] Miniaturized applications: Simple structure, small size, suitable for miniaturized devices (such as artificial hearts, microrobots).

[0024] Low noise: By using a linear motion, the mechanical noise of conventional rotary motors is avoided and operation is quieter. Description with drawings Fig. is a schematic structural diagram of a high-speed, short-distance reciprocating array electric motor of the utility model.

[0025] As shown in the illustration: 1. Magnet, 2. rectangular coil, 3. guide rail, 4. load-bearing terminal end, 5. base, 6. support frame. The specific embodiment

[0026] The high-speed, short-range, multi-track reciprocating array electric motor is described in more detail below in conjunction with the accompanying drawings.

[0027] Combined with Fig. The utility model will be presented in detail.

[0028] A high-speed, short-range, multi-track reciprocating array electric motor, the design of which is as follows: Magnet 1: Several groups of permanent magnets 1 or electromagnets 1 are distributed along the front and rear of the guide rail 6. The front and rear adjacent magnets 1 have the same polarity and form a successive magnetic field. The first group of magnets 1 is attached to the base. Sink:

[0029] The rectangular coils 2, each group of rectangular coils 2 can be formed by overlapping and winding a multitude of wires, the front end edge of the rectangular coil 2 is in the magnetic field of a magnet 1 and the corresponding rear end edge is in the magnetic field of an adjacent magnet 1.

[0030] The rectangular coil 2, together with the support frame 6, forms a tensioned body that ensures the transmission of the applied force. A lubricant should be present between the rectangular coil 2 and the magnet 1.

[0031] The coil material consists of a material with high conductivity (such as copper or aluminum) to reduce energy loss. Guide rail 3:

[0032] The guide rail 3 guides the magnet 1 along a defined track. Depending on the requirements, a light and hard material with low surface friction or a relatively soft and ductile material can be used. load-bearing connection end 4:

[0033] Connected to the rear end edge of the last set of rectangular coils 2 for the output of mechanical motion.

[0034] The force-receiving connection end 4 can be a robot arm, a piston, a vibrating head, etc., and the specific shape is designed according to the application scenario. Base 5:

[0035] It has a fixing function and is the starting point of the force. Support frame 6:

[0036] The support frame 6 is a rectangular, lightweight and hard object used to support the rectangular coil 2 to ensure that the force movement at the front end can be transferred to the rear end. The operating principle of this utility model: Theoretical foundations:

[0037] 1. Principle of electromagnetic induction. A current-carrying conductor intersects magnetic field lines in a magnetic field. The strength of the force is determined by the strength of the magnetic field and the current. The direction of motion is determined by the direction of the magnetic field and the direction of the current (left-hand rule).

[0038] 2. Reaction force and relative motion. Objects A and B exert forces on each other and move. If A is taken as the reference object, B moves relative to A; if B is taken as the reference object, A moves relative to B.

[0039] Operating principle: The base 5 remains stationary. The first group of magnets 1 causes the energized rectangular coil 2 to move in a straight line within the magnetic field. The energized rectangular coil 2 then causes the next group of magnets 1 to move in the same direction in a straight line, and so on. This process converts electrical energy into mechanical energy output. The direction of movement can be changed by altering the current or magnetic field direction. This achieves rapid, multi-track back-and-forth motion over short distances. When two or more motors are arranged in parallel, the force can be increased, and multi-track motion can be achieved by different groups of motors moving in different directions and at different speeds.

[0040] The specific implementation process of the utility model of the high-speed, short-range, multi-track reciprocating array electric motor is as follows: Forward movement: 1. When current is supplied to the rectangular coil 2, the rectangular coil 2 moves in the magnetic field due to the electromagnetic force. The direction of the force is determined by the current direction and the magnetic field direction (according to the left-handed rule). 2. In the attached Fig. The front edge of the rectangular coil 2 is pushed to the right by the previous group of magnets 1, moves to the right and drives the rear end edge of the rectangular coil 2 to move to the right through the support frame 6. 3. In the attached Fig. The rear end edge of the rectangular coil 2 is subjected to the thrust of the latter group of magnets 1 to the left and should be displaced to the left relative to the latter group of magnets 1, because the front end of the rectangular coil 2 is driven to the right by the thrust through the support frame 6 (the first group of magnets 1 is fixed and immobile), cannot move to the left, but can only move to the right and then pushes the latter group of magnets 1 to the right (the rear end of the rectangular coil 2 can also be fixedly connected to the latter group of magnets 1 to move the right pressure magnet 1). 4. In the attached Fig. The latter group of magnets 1 pushes the latter group of rectangular coils 2 to the right. 5. In the attached Fig. and so on until the last set of rectangular coils 2, which transfer the force to the force-bearing terminal end 4, which moves to the right and converts the electrical energy into mechanical energy. Reverse movement:

[0041] In the attached Fig. , if the direction of the current or the magnetic field is changed, the direction of movement changes to the left. Multi-track movement:

[0042] When two or more motors are connected in parallel, the strength can be increased, and multi-track movement can be achieved through the different directions and quantities of movement of different motor groups.
