Company Information:

Goodwell was founded in 1999 in Shenzhen city, China by Mr. Robert Wang, un ingénieur en électronique et possède un terrain d'usine situé dans la ville de Zhaoqing et couvre 27,000 square meters in 2015. Goodwell is the first manufacturer to apply electromagnetic levitation technology to craft products, cadeaux, jouets et présentoirs publicitaires et de les produire en masse ici en Chine, and has been being the leading specialist in the manufacture of “systèmes de lévitation électromagnétique » pour 19 years.Goodwell is the inventor of bottom levitation systems and patented them in china and USA. And all the produts are compliant with EMC, LVD, ROHS and FCC certificates. Goodwell is working with french designer and has a branch office in Paris.insisting on that qualities and techniques are the most important things, Goodwell is the most professinal team for ODM/OEM designs with different magnetic levitation devices.

We have been developing,designing and massive producing magnetic levitation products based on our patented levitation technology since 1999. Our products can be divided into three categories; levitation modules, display products and design crafts. All of our products are designed and produced in zhaoqing city, china.

HISTORYIn 1999, Mr. Li Liangqing and Mr. Robert Wang had the idea of combining their creative expertise on toolings and mechatronics respectively to execute a small workshop in shenzhen and produce mini magnetic floating globes.. They developed a kind of top levitation technology and began to massive producing the mini top floating globe and export to USA, which the globe is hanging in the mid air from the top.  Mr. Li and Mr. Robert had many brainstorm sessions on applications for this technology, and they decided to work with french scientists and designers for the electromagnetic levitation in the year of 2006. Together they all decided that bottom mangetic levitation is the most promising one and got china and US invention patents for the bottom magnetic levitation technologis. In November 2006, Mr. Li and Mr.Robert bought a 27000 square meter factory lands. In 2015, Goodwell is registered officially in Zhaoqing city and has a branch office in Paris for new designs and marketing.Since then the product catalogue has been expanded with levitation modules, afficher les produits, artisanat, cadeaux et différentes innovations et créations ODM/OEM.

Magnetic levitation system is widely used in the areas such as high-speed motion and precision engineering industry. In reality, a stable levitation with a 80mm air gap in maximum has been achieved, and the floating ferromagnetic object can carry a 2kgs load in maximum also has been achieved. We have already applied these in commerce, and the technology is also helpful to develop new kinds of levitation system for industries.

This magnetic levitation technology is a control method using a ring magnet for the stable levitation of a cylindrical ferromagnetic object. The levitation has a strong stability with anti-disturbance abilities, and weight can be placed on the floating magnet. The magnetic field created by the ring magnet provides stabilities in 3 degrees of freedom of the floating magnet, and a feedback control in the horizontal plane is introduced to the control system. The stable magnetic levitation refers that the floating object is static or is with a controllable rotation motion along one axis. The antigravity force for the stable levitation is provided by the base under the floating object. According to analytical calculation and experiments, the magnetic fields created by axially magnetized permanent-magnet rings have special properties. Along the symmetric axis, the direction of the magnetic field varies at two particular points. This interesting property provides stabilities of the suspending magnet.

The setup of the levitation device is shown in the drawing. An axially magnetized permanent-magnet ring whose north pole is on its upper surface is placed on the base of the setup. Three hall sensors are used for detecting the instantaneous coordinates of the floating magnet at three axes. The horizontal position of the floating magnet is controlled by two groups of coils. The north pole of the floating magnet is also on the upper surface, which is inconsistent with the common sense that unlike poles attract each other, not repelling each other to provide antigravity force for the floating magnet, which is the key point for this technology.

It is worth mentioning that the hall component for z axis acts just for a circuit protection. If the floating magnet is within the certain controllable area, there is no need to control its position along z axis.

Intuitively speaking, the magnetic field lines proceed from the north pole of a permanent magnet to the south pole. For an axially magnetized permanent-magnet ring, the magnetic field lines have two ways to travel. One is through the external space surrounding the magnetic ring, while the other way is through the internal space of the ring. Along the axis of symmetry, two points at which the magnetic field varies its direction exist.

The floating magnet is able to find its balance within a particular range along z axis, and the height of the air gap can change during levitation (when some weight is placed on or taken away from the floating magnet). Assuming that the size of the floating magnetic pallet remains unchanged, there is a corresponding relation between the height of air gap and the value of antigravity force provided by the ring magnet, which was shown in Fig. below. When the weight of the floating object changes (e.g., when a wooden block is placed on the floating magnet), the floating object will find its balance at a new position. If the floating magnetic pallet jumps up because of some distur-bance, the direction of the resultant force acts on the magnet may be downward. This property significantly reduces the overshoot of the balance along z axis. Which means the load on the magnet pallets varies, and the air gap will be varied to reach the balance.

The movement of the floating magnet along x axis and y axis in the horizontal plane are controlled by the feedback system. Two groups of coils are used to trap the floating magnet at the center of the magnetic field created by the ring magnet. Feedback control is implemented along the two dimensions separately. Hall components which are able to detect the magnetic field created by the floating magnet and transfer it into voltage signals play the role of sensors. In order to eliminate the effect of the magnetic field created by the ring magnet and coils, the two coils are placed symmetrically along one axis and the hall component is located at the center of the ring magnet and two coils, which is shown in Fig. below. Currents with the same intensity but reversed direction are added into each coil so that the magnetic field created by them make a cancelation at the center.

 Under the circumstance of the stable levitation, a reference voltage is selected. Within a small range, a linear relationship is held between the difference from the input voltage of the hall component to the reference voltage and the deviation of the floating magnet from the balance point, where the difference value is zero. Thus, simple negative feedback can achieve the stable control. Besides, because of errors and interference. Some special mechanisms are introduced such as floating reference voltage. It is shown that the levitation of the cylindrical ferromagnetic object is stable. It has an anti-overturn ability and an anti-disturbance ability. The requirements needed for the levitation is not harsh at all, and the device can be even put on a leaning platform.
