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 […]

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 […]

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 […]

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 […]

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 […]
