 As a typical application case of a bonded magnetic compound, a magnetic roller for the printer is the main component that carries toner in the printer. Comparing to the traditional sintered magnetic material, the magnetic roller made of bonded magnet can realize with multiple radial poles, like 4poles, 5poles, 6poles. Furthermore, the length to diameter ratio of the magnetic roller can reach to more than 30, which can not be realized in the sintered magnetic material. The magnetic roller made of the magnetic compound through injection molding or extrusion greatly improve production efficiency, and have the advantages of good dimensional consistency, uniform magnetic field distribution, and excellent mechanical properties. It achieves high-quality development effects for printers.

 The rotor for the bladeless fan that made of injection molding magnetic compound can solve the sintered ferrite rotor’s issues, like complicated processing and brittleness of the finished products. The recommended material is ferrite/PA12 compounds. The insert molding process realizes efficient production and improves the cracking problem of sintered magnetic rings during the second injection. The bonded ferrite has excellent mechanical properties and will not be easily cracked during transportation and assembly. The rotor made of ferrite compound guarantees the uniformity of dimension and magnetic properties for each product, thereby improving the noise and vibration problems of the motor.

 Home-Appliances-2

 The rotor with radial and quadrupole magnetization for the freezer. Comparing to the sintered arc magnet that pasted by glue, the rotor made by injection reduces the need for complicated manual processes. The injection molding process ensures reliability and avoids the hidden danger of falling off during motor operation. The recommended material is ferrite/PA12 compounds. As the diversity of magnetic pole orientation for the rotor made of the magnetic compound, we use a special magnetic field waveform design, which makes the product with driving and induction effect. Because of injection molding, the uniform of dimension and magnetic field distribution make the motor with excellent dynamic balance. And it finally makes the motor with low noise and stable operation.

 Home-Appliances-3

 The rotor of electronic expansion valve in the thermal management system. The electronic expansion valve (EEV) controls the flow of refrigerant entering a direct expansion evaporator. It plays an important role to reduce energy consumption. With small size, multiple poles, high precision in dimension, EEV has the requirement of not cracking in high and low-temperature environments for a long time using in the refrigerant . The rotor that made of bonded ferrite/PPS or NdFeB/PPS will meet those requirements. Ferrite/PPS series ((BH) max = 1.6MGOe) is applied to the rotor with low power, and NdFeB/PPS series ((BH) max = 2-8MGOe) is recommended to use in the EEV rotor with high power. With the increasing demand for automotive thermal management systems, we are also constantly developing the magnetic compound with higher magnetic performance, higher cost-effective and lower demagnetization rates at high and low temperatures to meet the design requirements of the new generation of EEV rotors.

Industrial magnet product encyclopedia from Newland

Every day, different people working in different industries are dealing with a wealth of equipments or devices that contain various magnetic parts or custom magnet components. In this article, Newland factory, one of influentially large magnet product manufacturing facilities, will walk you through magnet details about its classification, material, manufacturing workmanship, pros and cons respectively. When it comes to magnet product buying guides, welcome to consult Newland magnet factory.

Coming next is about its category.

There are many kinds of magnets based on different standards, which nonetheless are generally divided into permanent magnet and soft magnet, in which, the former can be divided into two categories:

And its texture is hard, while the performance is stable, factored with low cost, its application is extremely extensive. Nevertheless, because of its strong chemical property, it is a must to be coated with other metals on the surface. ( say Zn,Ni, electrophoresis, passivation, etc.)

3. SmCo magnet (SmCo) can be sorted into SmCo5 and Sm2Co17 according to its different components. Samarium cobalt's development can't be fully unlocked due to its expensive cost. SmCo, as a rare earth permanent magnet, it has high magnetic energy effect (14-28MGOe), plus reliable coerce and good temperature characteristics. Samarium cobalt magnets are better suited to work in high temperatures than Neodymium iron boron magnets.

Segment Motor Magnet

Segment Motor Magnet

arc shaped Neodymium magnets

wind generators Segment Motor Magnet

Servo motors Segment Motor Magnet

Segment or arc shaped Neodymium magnets are widely used instead of expensive radial rings in electric motors.

Horizon have been focusing on the development and production of high end series of NdFeB rare earth permanent magnets, which are widely used in permanent magnet motors and generators.

Due to their advantage, NdFeB rare earth magnets have become one of the most important components of permanent magnet motors and generators, whose performance and life time mainly depends on the quality of magnets. Generally speaking, the working environment to motors and generators is very harsh. In order to adapt to this working environment, we have been devoting ourselves to research and develop NdFeB rare earth magnets specially used for permanent magnet motors and generators since its foundation. For this application, the magnets are available in a wide range of shapes such as block, ring, segment, loaf, wedge, etc.

Currently we are producing serials of high end grades, like H, SH, UH, EH and AH for NdFeB with following three characteristics:

High intrinsic coercivity Hcj: high to >35kOe (>2785 kA/m) which increases magnets demagnetizing resistance

Low reversible temperature coefficients: low to α(Br)< -0.1%/ºC and β(Hcj)< -0.5%/ºC which increases magnets temperature stability

Low weight loss: low to 2~5mg/cm2 in HAST testing condition: 130ºC, 95% RH, 2.7 ATM, 20 days which increases magnets corrosion resistance

Although the low weight loss material improves its corrosion resistance, the coating is still often required by customers. If customers require coating, we suggest magnets be phosphated or passivated. However, more and more customers change to use magnets without any coating, because uncoated magnets have much better glue cohesiveness than coated magnets.

stepper motors Segment Motor Magnet Applications:

Servo motors, elevator motors, traction motors, stepper motors, disc type motors, wind generators, etc.

Size:

Normal Size Range: L (Length): 1~180mm, W (Width): 3~180mm, H (Height): 1.5~100mm

Maximum Size: L50 x W180 xH80mm, L180 x W80 xH50mm,

Minimum Size: L1x W3 x H2mm

Orientation Direction Size: Lower than 80mm

Tolerance: Generally +/-0.1mm, Particularly +/-0.05mm

Segment Motor Magnet

Machining Method:

Generally the segment requires grinding and EDM cutting from the big block. Sometimes, the approximate final shape achieved after the EDM cutting needs processing with a shaped diamond grinding wheel which provides the precise dimensions and speeds up the machining process. Prior to coating, the small segment needs vibration tumbling and the big segment needs manual chamfering.

Main Test Items Prior to Delivery:

In order to ensure NdFeB magnets to meet requirements, we main test following items: size, weight loss, magnetic properties, flux, flux density, angle deviation, magnetic loss, appearance, coating thickness, corrosion resistance, etc.
