Magnetic bearing applications

My goal is, along with my team, to provide technical solutions and design and manufacturing services in the fields of magnet materials and plastic-magnet integration.

We focus on high-end markets across various industries, including medical, oil and gas, aerospace, and consumer electronics applications.

Magnetic bearings are constructed with permanent magnets arranged in a ring, utilizing attraction or repulsion forces between the magnets to achieve suspended support. The bearing system does not include active control devices and does not require an external power supply.

| Wind turbines: Wind turbine magnets are important to wind turbines. Despite generating low torque at low wind speeds, rotor systems supported by passive magnetic bearings can still efficiently utilize low wind resources. The bearing system provides sufficient load capacity to cope with varying wind speeds and directions, thereby meeting system stability requirements.

At Tengye, we’re thrilled to be early participants in your new projects. We hope to bring our knowledge and experience to the forefront by actively engaging in your upcoming projects.

Magnets frequently come assembled with metal or plastic components. By offering these products together, we can streamline your process and save you valuable time.

Tengye is a magnet company that collaborates with engineers during the early stages of product development to co-develop and manufacture the highest quality magnets and advanced, complex magnetic assemblies.

Permanent magnetic bearing

| Passive magnetic bearings also suffer from uneven magnetization, especially after prolonged operation, leading to significant unevenness in magnetic field distribution and affecting system stability. Moreover, the brittle nature of the ring magnets makes them susceptible to impact-induced fractures in unstable systems.

As the Managing Director of Tengye, I bring a wealth of knowledge and experience to the table, with expertise spanning sales, technical aspects, purchasing, and more.

Active magnetic bearing

As a comprehensive magnet system solutions provider, we not only supply CNC precision machining parts, cast metals, and stamped metal parts but also specialize in designing and manufacturing plastic molds.

Magnetic bearing vs ball bearing

Passive magnetic bearings operate without mechanical contact, enabling high rotational speeds. They offer advantages such as minimal mechanical wear, low energy consumption, low noise, long lifespan, and no need for lubrication, making them particularly suitable for high-speed and cleanroom environments.

Passive magnetic bearings primarily comprise permanent magnet rings made from neodymium iron boron magnets, serving as the stator and rotor. Attraction or repulsion forces between these permanent magnets control their relative positions, maintaining stable suspension.

However, the remanence of the permanent magnets remains largely unchanged after their initial magnetization. Therefore, passive magnetic bearings cannot actively adjust the magnitude and direction of magnetic forces like active magnetic bearings can. Moreover, rotors are susceptible to external disturbances, leading to instability or vibration, hence they are typically used in conjunction with active magnetic or mechanical bearings.

Passive magnetic bearings use magnetic fields to generate forces separating the stator and rotor, allowing the rotor to float mid-air for non-contact support. By varying parameters such as the size, shape, magnetization direction, and arrangement of the magnetic rings, different devices can be derived to suit various fields and applications.

Passive magnetic bearing

| High speed: Passive magnetic bearings allow rotors to operate at high speeds primarily limited by material strength, enabling operation under supercritical conditions with speeds reaching hundreds of thousands of revolutions per minute.

| No contact & no wear: Magnetic levitation bearings operate in a suspended state without contact between moving surfaces, eliminating mechanical friction and fatigue. This addresses issues of component wear and replacement, and eliminates the need for lubrication systems, thereby saving space and avoiding environmental pollution caused by such systems.

We supply NdFeB and SmCo magnets. What makes us special is our preference for working with specially shaped magnets or magnets with unique magnetization patterns and requirements.

What is magnetic bearing in surveying

| Low vibration & low noise: Magnetic levitation bearing rotors avoid the significant vibration and high-decibel noise caused by contact collisions in traditional bearings during operation. This enhances stability, reduces maintenance costs, and prolongs operational lifespan. Moreover, the power consumption of suspended magnetic bearings is only 6% to 25% of traditional mechanical bearings. At a speed of 10,000 rpm, their power consumption is approximately 15% of that of mechanical bearings.

| Magnetic levitation heart pumps: When using a heart pump to provide blood circulation power, mechanical friction can generate heat. Using passive magnetic bearings as a support system can enhance the stability of the heart pump during suspension, reducing heat generation. A hybrid bearing support system combining radial permanent magnetic bearings and axial electromagnetic bearings allows the heart pump to feature simplicity in structure, compact size, and low power consumption.

We have manufactured advanced magnetic assemblies for a wide range of industries, including medical, electrical, aerospace, electronics, oil and gas, and more.

| Passive magnetic bearings suffer from instability issues and require auxiliary support of active or mechanical bearings. Moreover, their application is limited by fewer manufacturing facilities and installation difficulties compared to mechanical bearings.
