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 […]

Wide Application of Magnetic Pump

Description A magnetic pump consists of three parts: a pump, a magnetic actuator, and an electric motor. The key component of the magnetic actuator is composed of an external magnetic rotor, an internal magnetic rotor, and a nonmagnetic isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can […]

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 […]

What is difference between Samarium cobalt and Alnico magnet

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 […]

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 […]

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, 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 […]
