Halbach Array

What is a Halbach Array? A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while reducing?the field to near zero on the other side.? In 1979, American physicist Klaus?Halbach discovered this special arrangement of permanent magnets while doing electron acceleration experiments, so we[…]

Thin NdFeB magnets in smart devices

Small NdFeB Magnets in Smartphones Neodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. ?These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus[…]

Application of Injection Molded Magnet

Injection Molded Magnet One of the more important developments in magnetic materials is injection molded magnet, which has opened a new world of application opportunities. The processing temperatures employed to blend and mold the material mixture are low enough to allow many different magnet powders to be used alone or in combination in the polymer[…]

Permanent Magnet Motor VS. Induction Motor Efficiency

As the name implies, a permanent magnet motor uses permanent magnets?on the rotor. The alternating current applied to the stator results in rotation of the rotor. Because the magnets are permanently magnetized, the rotor can run synchronously to the switching AC current. The slippage necessary in induction motors is eliminated, improving your heat efficiency. The[…]

Does Tesla use permanent magnet synchronous motors? Permanent magnet motor VS Induction motor

Early Tesla Model S and Model X used asynchronous induction motors. With the upgrades, Tesla brought permanent magnet synchronous motors to Model S and Model X models for the first time in 2019. In Tesla’s latest Model S/Model X Plaid version, Tesla uses three permanent magnet synchronous motors to drive the vehicle, enabling the Plaid[…]

what is electric permanent magnet chuck

Overview The electric permanent magnet suction cup refers to the suction cup that relies on the permanent magnet magnetic steel to generate the suction force, and uses the excitation coil to control the suction force of the magnetic steel to play the role of the suction switch. Advantages: high precision, no thermal deformation, energy saving.[…]

How does Magnetic Filtration work?

What is Magnetic Filtration? Magnetic filtration, also known as magnetic separation, is a method that removes iron particles from products that are in liquid or slurry form and allows for fluid to flow around a magnetic rod or core. This magnet attracts ferrous particles and removes them from the fluid, ensuring that clean fluids are[…]

Application of magnet in oil and gas pipeline inspection

Due to corrosion, cracks or?damage, long-distance oil and gas pipelines may leak during use. Oil and gas leakage will not only pollute the surrounding environment of long-distance pipelines, but also may cause safety accidents such as combustion and explosion, resulting in huge economic losses. . Therefore, long-distance oil and gas pipelines need to be regularly[…]
