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[…]
How does a stepper motor work? In mechanical design, we often use stepper motors, such as scanners, printers, cameras, ATM machines, etc. that are common in life, and the linear motion of the synchronous belt shaft of common machines in factories. What is its working principle? The working principle of a stepper motor, in general[…]
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[…]
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[…]
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[…]
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[…]
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.[…]
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[…]
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[…]
Electric permanent magnet chuck 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.
