High Performance Hollow Cup Neodymium Cylinder Magnet

High Performance Hollow Cup Neodymium Cylinder Magnet

The hollow cup magnet, which is often called the magnetic ring, why? Because the magnetic ring itself is a hollow product. Why is the magnetic ring hollow? This is to make use of the regular characteristics of the magnetic ring. The hollow core of the magnetic ring is mainly simple in use and convenient to use. The hollow magnetic core can better penetrate into each interference source line, wrap the interference source line, and the characteristics of the magnetic ring can also be relatively horizontal, greatly improving the magnetic ring. The effect.

Features& Advantage:

• High Power Density: Concentrated and strong magnetic field enables high torque output and fast response in motors, ideal for precision drives (e.g., robotic arm joints).
• High Efficiency & Low Energy Consumption: Optimized magnetic circuit reduces eddy current losses, improves motor efficiency, and extends battery life.
• Precise Control & Smooth Motion: Uniform magnetic field combined with coreless design reduces cogging torque, enabling smoother operation and high-precision positioning/speed control.
• Long Lifespan & High Reliability: No mechanical wear (contactless transmission), strong resistance to vibration and shock, suitable for high-frequency, high-dynamic industrial applications.

 

 

Hollow cup motor is a special type of motor, with high efficiency, high speed, low noise, small size, light weight and so on. In many applications, such as drones, robots, medical devices, etc., hollow cup motors have become the preferred drive mode.
