A magnetic switch is an electrical switch that closes or opens contacts in a magnetic field. The switch remains on as long as a strong magnetic field is present and opens when the field is removed. Magnetic switches include reed switches, Hall sensors, and electromechanical relays. The simplest switches include magnetic window switches and door […]
The traditional saying is that their back electromotive force is different, BLDC is close to a square wave, and PMSM is close to a sine wave. In terms of control, BLDC generally uses a 6-beat square wave drive to control the phase and reverse time of the square wave, and PMSM uses FOC. In terms […]

Magnetic brakes and clutches use permanent magnets to generate resistive torque and require no electricity to operate, resistive torque is constant and independent of slip speed. By driving the body of our magnetic brakes and using the shaft as the output, these permanent magnet hysteresis brakes can be used as adjustable inline torque limiting magnets […]

The magnetic coupling mainly consists of an outer rotor and an inner rotor The magnetic coupling mainly consists of an outer rotor and an inner rotor. The inner wall of the outer rotor is covered with high-quality magnets, and the two adjacent magnets are arranged in opposite poles. The inner rotor also has two magnets […]

Common ground: Both belong to high temperature-resistant permanent magnets. Among them, the working temperature of Alnico magnet can reach up to 550℃, the maximum working temperature of samarium cobalt 1:5 type is 250℃, and the maximum working temperature of samarium cobalt 2:17 is 350℃; Both do not require surface treatment (except for use in special […]

A geophone is a highly sensitive ground motion transducer that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the baseline is called the seismic response and is analyzed for the structure of the earth, which has been used by seismologists and geophysicists […]

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, allowing 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 returned […]

Magnet is one of the most common items in our daily life. It has a wide range of applications and can be used in industry, manufacturing, electronic products, etc. Magnets can be divided into two categories, namely permanent magnets and non-permanent magnets, and permanent magnets can be natural magnetite or artificially made magnets. Among all […]

By their very nature, every permanent magnet contains some form of iron. Iron displays the most dramatic ferromagnetic properties of all elements, which is why it is found in the most powerful magnets. However, iron is highly reactive with water and then causes magnets with high iron content very susceptible to corrosion. Other ferromagnetic elements […]

Neodymium magnets are a powerful type of magnet that led to their use in many modern technologies, as well as in the fields of medicine and dentistry, particularly, on body systems, tissues, organs, diseases, and treatment. Neodymium magnets are incorporated in medical devices for example in magnetic resonance imaging devices to diagnose and treat chronic […]
