Axially magnetized multipole magnets are the core materials of magnetic transmission devices, especially those used in magnetic disc transmission devices. This article primarily discusses the application of these magnets in planar magnetic transmission devices.
Magnetic transmission devices typically utilize the interaction between magnets to achieve torque transmission. Due to their excellent magnetic performance, axially magnetized multipole magnets ensure the efficient and stable operation of magnetic transmission devices.
Magnetization Direction of the Magnets
The methods for magnetizing magnets primarily include axial magnetization, diametrical Magnetization, and radial magnetization, among others. Generally, the magnetizable object is placed in a magnetic field formed by a coil with direct current passing through it, which is essentially done using a magnetizer.
Axially Magnetized Multipole Magnets
Multipole magnetization involves the magnetization process of more than two pairs of magnetic poles on the same magnet. It is a complex, specialized technique that primarily utilizes pulsed magnetic fields. The effectiveness of magnetization is related to the magnetization coil and the size and performance parameters of the magnets.
Axially Magnetized Multipole Magnets in Magnetic Transmission Devices
The basic structure of the transmission device: Two identical diameter magnets are installed in an alternating NS pole arrangement. During use, the two magnets are separately mounted on the driving shaft and the driven shaft, leaving a certain air gap in between. The N pole of magnet A attracts the S pole of magnet B opposite to it while repelling the N poles on either side of magnet B, ensuring that the driven shaft and the driving shaft maintain synchronous rotation within a certain torque range.
Although magnetic transmission can achieve synchronization, it cannot realize precision synchronous transmission. This type of planar magnetic transmission device has a simple structure and does not require high coaxiality between the two shafts during installation. Therefore, its simple structure and low cost are the main advantages of planar magnetic transmission devices.
Types of Magnets in Magnetic Transmission Devices
| Ferrite Materials: Due to their low magnetic performance, ferrite magnets can only transmit small torque.
| NdFeB Magnets: Neodymium iron boron magnets have a high magnetic energy product, require less quantity, and have good processing properties, making them commonly used in magnetic transmission devices.
| Samarium Cobalt and Alnico Magnets: Suitable for high-temperature environments, but samarium cobalt and Alnico magnets have high costs that increase material expenses.
Applications of Magnetic Transmission Devices
Unlike traditional transmission devices, magnetic transmission devices feature low noise and low vibration characteristics, while also improving transmission efficiency. They are now widely used in industries such as chemicals, pharmaceuticals, and food.
