Magnetoelectric push-pull linear motor

Abstract

A magnetoelectric push-pull type linear motor is composed of two stators and a rotor, and the characteristic that like poles of magnetic poles of an electromagnetic field are arranged and opposite poles of magnetic poles of the electromagnetic field attract each other is utilized. Under the control of the electronic circuit, the magnetic poles of the electromagnetic field are continuously converted at a high speed. A push-pull type linear motor is generated between the mover and the stator, the same poles are arranged as push force, and the opposite poles are attracted as pull force. And the power drives an optical shaft (piston) to do high-speed reciprocating linear motion in the air cylinder. The one-way valve operates to generate air suction, air discharge and compression, so that the air pressure is increased or the water pressure is increased. Or the device can be applied to a punching machine to realize the functions of metal pressing, shearing and the like. And the function of the linear motor is realized. The motor can also be applied to mechanical linear motion. The advantages are achieved; a traditional rotary motor, a crankshaft, a connecting rod and other complex mechanical structures are omitted, and cost is saved. The reciprocating speed is high, efficiency is high, and energy is saved. The device is small in size and light in weight. The processing difficulty is low and the production efficiency is high. The power can be large or small, and the plasticity is high. The application range is wide, and is shown in the figure 3 in linear motion of all machines such as air compressors, hydraulic presses, hydraulic presses and punching machines.

Description

Technical field:

[0001] This motor is used in air compressors, hydraulic presses, hydraulic presses, punching machines, metal shearing and linear mechanical motion. Technical background:

[0002] The air compressors, hydraulic presses, hydraulic presses, punching presses, etc. currently used at home and abroad all use traditional rotary motors to drive crankshafts, connecting rods, and other mechanical structures to convert them into linear motion to do work.

[0003] The disadvantages are: complex machining, large size, high cost, high energy consumption, slow speed, low energy utilization, etc. Summary of the invention:

[0004] This motor: Get rid of a series of mechanical structures such as rotary motors, crankshafts, connecting rods, etc. Utilize the characteristics of the electromagnetic field that the magnetic poles of the same poles repel each other and the opposite poles attract each other. Under the control of the electronic circuit, the magnetic poles of the electromagnetic field can be quickly changed. Form NN or SS like poles repel each other as thrust, or NS opposite poles attract each other as pulling force. Then a push-pull magnetic force is generated. This motor uses this force to drive the optical axis (piston). Through the operation of the one-way valve, it can realize the suction, exhaust and compression to increase the air pressure and water pressure, and can also realize the pressing and shearing functions of the punching machine. Structure and principle:

[0005] The motor is composed of two stators, a mover, an electromagnetic field coil, an optical axis, a linear bearing, a bearing support frame, an electronic circuit, a machine base, etc.

[0006] It takes the optical axis as the center, fixes the mover in the middle of the optical axis, and inserts the optical axes on the two outer sides of the mover into the inner holes of the left and right stators and linear bearings. The mover is suspended in the air and can move left and right through the bearing support frame. The whole is a horizontal combination. Figure 3 As shown. If used on a punch press, it is a combination of upper and lower parts. Figure 4 shown.

[0007] The two stators are fixed on the inner sides of the two bearing support frames. The inner sides of the two stators have the same polarity.

[0008] The electromagnetic field coils embedded in the mover and stator must correspond one to one, thus forming four parallel magnetic surfaces.

[0009] This motor uses these four parallel magnetic surfaces as power. Under the control of the electronic circuit, the magnetic poles of the electromagnetic field can be continuously changed at high speed to generate push-pull magnetic power on the mover. The optical axis (piston) can make rapid reciprocating movements in the cylinder. Through the one-way valve, suction, exhaust and compression can be generated, which can increase the air pressure, increase the hydraulic pressure, and perform stamping and shearing. The motor can achieve the function of linear motion and work. The above is the basic working principle of this magnetoelectric push-pull linear motor. Figure 3 , as shown.

[0010] In order to increase the power of the motor, multiple stators and multiple movers can be provided to achieve greater power of the motor. Description of the drawings:

[0019] 1. The two inner holes of the support frame should be through, and a horizontal and fine-tuning moving device should be set at the bottom of the support frame. It should be firmly combined with the base.

[0020] 2. Electronic circuit: First, the alternating current must be converted into direct current. Then any of the following circuits can be used, such as bistable circuit, travel switch circuit, thyristor circuit, multivibrator, trapezoidal square wave pulse circuit, etc. Control relays or AC contactors, turn on and off in turn, and change the polarity of the electromagnetic field.

[0021] 3. Machine base: To reduce the weight of the machine body, the machine base and two bearing support frames can be made of aluminum alloy.

[0022] 4. The mover and stator; the core material of the two electromagnets; must be made of electrical iron.

[0023] 5. The optical axis material in the mover core must be made of non-magnetic and wear-resistant metal material. Economic Assessment:

[0024] This motor removes the rotating motor, crankshaft, connecting rod, oil box and other mechanical components, which greatly reduces the machining cost and material cost, which accounts for about two-thirds of the total, which is equivalent to reducing two-thirds of the cost. This linear motor will have a relatively large competitiveness in the market competition.
