Types and Precautions of Surface Coating

Surface coating is the most basic and common surface treatment method. Types of Coating The coating can be divided into electroplating, barrel electroplating, rack plating, electroless plating, and physical vapor deposition. Electroplating (EP) refers to the deposition of a metal or alloy layer with good adhesion on the substrate by electrolysis in order to obtain […]

Magnetic self-priming construction elevator protective door

Background In the construction process of high-rise buildings now, all need to arrange outdoor construction elevators, and the construction elevator is arranged on the outer wall of the building. Each floor of the building is provided with a reserved opening opposite the construction elevator, that is, the elevator entrance, and construction personnel can enter each […]

What is a Magnetic Switch?

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 difference between BLDC and PMSM motors

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 […]

How do Magnetic Brakes & Clutches operate?

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 […]

Principle and design of magnetic coupling torque transmission

magnetic couplings

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 […]

The principle of Geophone magnet

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 […]

Application of Neodymium Magnet in Healthcare Field

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 […]

Application principle of magnet in speedometer

A speedometer or a speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the 1900s, and as standard equipment from about 1910 onwards. Speedometers for other vehicles have specific names and use other means of […]

How to choose Fishing magnet?

What Is Magnet Fishing? Similar to metal detecting where objects are found on land using a metal detector, magnet fishing is about finding metal objects in bodies of water using strong magnets. Have you always imagined what could be at the bottom of a lake near where you live? There have been interesting finds by […]
