  • What is a Magnetic Switch?

    What is a Magnetic Switch?

    A magnetic switch is an electrical device that opens or closes its contacts under the influence of a magnetic field. When exposed to a magnetic field, the switch remains closed; when the field is removed, it opens. These switches are widely used for automation, safety, and industrial control due to their reliability and simple design.

    BLDC vs. PMSM Motors: What’s the Real Difference?

    Navigating the world of brushless motors can be confusing. While brushless DC (BLDC) and permanent magnet synchronous motors (PMSM) are both brushless, they are not the same. Understanding their key differences is crucial for selecting the right motor for your application.

    The core distinction lies in their design and how they are controlled.

  • Principle and Design of Magnetic Coupling Torque Transmission

    Principle and Design of Magnetic Coupling Torque Transmission

    A magnetic coupling primarily consists of two core components: an outer rotor and an inner rotor.

    • Outer rotor: The inner wall of the outer rotor is embedded with high-performance permanent magnets, arranged in alternating north and south poles.
    • Inner rotor: Equipped with corresponding magnets arranged in opposite polarity, its outer circle is precisely machined to minimize clearance.
    • Isolation sleeve: Positioned between the two rotors, this barrier prevents leakage of dielectric fluid while maintaining magnetic field integrity.

    This non-contact design allows torque to be transmitted across the isolation barrier without physical connection.

    Difference Between Samarium Cobalt and AlNiCo Magnets

    Samarium Cobalt (SmCo) and AlNiCo are both high-temperature permanent magnets widely used in industrial applications. While they share certain similarities, their differences in magnetic strength, cost, mechanical performance, and application suitability determine which material is more appropriate for specific use cases.

    Geophone Magnet Principle: Types, Frequency Response, and Magnet Selection

    A geophone is a highly sensitive ground motion transducer that converts ground vibrations into electrical signals. The core components include:

    • Magnetic Core & Coil – An electric coil surrounds a suspended magnetic core.
    • Permanent Magnet – A case-mounted magnet creates the magnetic field.
    • Electromagnetic Induction – When the ground moves, the housing moves with it while the coil tends to remain stationary. The relative motion between the coil and magnet induces a voltage, proportional to vibration velocity.

    This induced signal is called the seismic response, which seismologists and geophysicists analyze to study subsurface structures.

    How Does Magnetic Filtration Work? An Industrial Guide

    Magnetic filtration, also known as magnetic separation, is a process designed to remove ferrous contaminants from liquids, coolants, and slurries. The fluid flows around a high-intensity magnetic core or rod, and ferrous particles are drawn out of the stream and held in a magnetic trap. Once full, the filter can be cleaned and reused, providing a sustainable and cost-effective solution for industrial fluid management.
