The Daily Maintenance of Magnetic Products Magnets show up everywhere – factories, gadget assembly, scrap sorting, machine control. They grab, move, sense, pull apart metals using invisible push and pull. Hard to tell just by looking, but folks often think these blocks need no care once set in place. Few people notice how a magnet [...]
Difference Between NdFeB Magnet and Electromagnet Everywhere you look, machines rely on invisible pushes and pulls to work right. Whether it is an appliance at home or robots building cars, tiny forces keep parts in place or set them in motion. Figuring out how NdFeB magnets differ from electromagnets often ties back to something practical. [...]
What Are the Performance Parameters and Application Scenarios of Permanent Magnet Couplings? What Are the Performance Parameters of Permanent Magnet Couplings? Whether or not a permanent magnet coupling is suitable for a particular application is determined by performance parameters. These factors are responsible for affecting safety, efficiency, and service life. Rated Torque The rated torque [...]
What Is a Permanent Magnet Coupling? Permanent magnet coupling can be defined as a non-contact type of mechanical device utilized for transmitting a certain level of rotational torque with the use of magnetic force. It helps in the transfer of torque from a driving shaft, primarily fixed on an electric motor, without the interaction of [...]
Torque Limiting Permanent Magnetic Coupling Product introduction of Torque Limiting Permanent Magnetic Coupling: The Permanent Magnet Coupling is a device which transmits the torque from the motor to the load through the air gap between the conductor ring and the permanent magnet rotor. It can realize the transmission mode without mechanical connection between motor and [...]
Advantages and Disadvantages of Permanent Magnet Couplings “Permanent Magnet Couplings have many advantages but also have limitations. Buyers have to consider these limitations while deciding on these couplings.” Advantages of Permanent Magnet Couplings 1. No Mechanical Contact No physical contact is necessary to transmit the torque. No friction is involved due to the lack of [...]
Magnetic Shaft Coupling in Rotary Drum Pulper As we all know, the drum pulper is very important equipment in the waste paper deinking and pulping production line. Through the rotation of the drum, the waste paper raw materials sent by the conveyor are continuously sheared and pushed forward. The drive system of the drum pulper [...]
Conveyor Belt Magnet Coupler in Coal Preparation Plant In this post, we talk about how a super large coal preparation plant uses the conveyor celt magnet coupler to improve efficiency and save cost. The super-large coal preparation plant processes 12 million tons of washed raw coal every year. In order to save energy and improve [...]
Torque Limited Magnetic Coupler in Crusher The double-geared roller crusher has the advantages of light weight, small size and low energy consumption, and is suitable for various operating environments, and has been widely used in coal mines. In the open pit coal mine, the large volume of raw coal is crushed by the double-geared roller [...]
What Is a Ring Magnet, Donut Magnet, Annular Magnet A ring magnet (you’ll also hear “donut magnet,” “annular magnet,” or “magnetic ring”) is basically a washer-shaped permanent magnet—round on the outside with a hole through the center. That hole is what makes it so useful: you can slip it onto a shaft, rod, or screw [...]
Amazon's IATA Reporting Requirements for Magnetic Products Recently, many Amazon sellers have run into confusion during the “magnetic product” review process. Amazon often asks for a magnetic testing report that complies with IATA standards, and some review notes specifically mention measuring the magnetic field strength (in gauss) at 2.1 meters from any surface of the [...]
Surface Treatment of NdFeB Magnets – Passivation To improve the corrosion resistance of NdFeB magnets, it is usually necessary to treat the surface of NdFeB magnets. Common surface treatment methods for NdFeB magnets include phosphating, electroplating, electrophoresis, and vapor deposition. In our last article, we introduced electrophoresis, so in this article, MPCO will introduce another [...]
