Product Description

Muti-Pole Magnetized Bonded Magnet Description
Bonded neodymium magnets are isotropic and have the advantage of more advanced shapes compared to sintered magnets. The magnet needs to be coated with a layer of black or grey epoxy or perylene to protect it against corrosion. Bonded magnet is a kind of composite material composed of magnetic powder and binder. Bonded magnets are distinguished for complex shapes, high dimensional precision, tight tolerance, no need for subsequent mechanical machining, integration capability with other functional parts, and suitable for mass production. Magnetic powder, volume fraction of binder, and interior porosity play a decisive role in the magnetic properties of the bonded magnet.

Muti-Pole Magnetized Bonded Magnet Application

This product is used in the motor of the gate machine. The working principle of the gate machine motor is based on electromagnetic induction and the change of current direction. The motor can realize the rotation of the rotor through the change of current direction. When the current passes through the winding, the magnetic field generated interacts with the magnetic field of the permanent magnet to generate torque, causing the rotor to rotate. The power supply generates a torque to drive the arm to move. The permanent magnet motor composed of NdFeB magnetic materials in the motor is light and flexible, easy to transport, and easy to carry, which brings great convenience to the shipment of the motor. After magnetization, the product can maintain its magnetism for a long time, and its performance is more stable; the accuracy is controllable, the operating noise is small, the load capacity is strong, and the motor error can be controlled within 0.1%; it can be flexibly adjusted to maximize the operation efficiency and reduce energy consumption. Compared with other permanent magnetic materials, NdFeB magnets have better stability and dynamic response, can improve motor efficiency and power density, and make motor performance superior. Therefore, they are widely used in a variety of motors to improve control accuracy and work efficiency.

Quality Assurance

Our products are manufactured to exacting standards and are manually and machine inspected to meet your specifications.

 

Factory Equipment

 

Product Maintenance
The product storage environment should be dry and free of corrosive gases.
Place it in a ventilated, light-proof, and non-magnetic environment as much as possible.
The storage temperature should be controlled at around 20ºC - 30ºC.
During use, it is necessary to prevent moisture from entering the interior or surface of the magnet. When storing, it should be covered with a moisture-proof cover or a protective layer to prevent the magnet from being subjected to severe collision and vibration, to avoid reducing the magnetic force or breaking.
