Introduction
Arc Neodymium Magnet for Servo Motor is a high-performance permanent magnet made of neodymium iron boron alloy material, with an arc shape to meet the specific design requirements of servo motors. This magnet is composed of neodymium (Nd), iron (Fe) and boron (B) elements, and is processed through precision technology. The magnetic force is evenly distributed and can fit closely with other components inside the motor.
Features
High Magnetic Energy Product Improves Magnetic Density
The Magnetic Energy Product (BH) of Arc Neodymium Magnet for Servo Motor has different advantages in different grades, with the 30SH grade ranging from 223-247 kJ/m³, while the 42SH grade can reach 320-343 kJ/m³. This means that as the grade increases, the magnet can provide stronger magnetic density and higher magnetic field output, thereby achieving more efficient energy conversion and precise control in the servo motor.
High Coercivity Enhancement
Arc Neodymium Magnet for Servo Motor has a high coercivity (Hcb), usually greater than 10 KA/m, up to 11.8 KA/m (such as 40SH and 42SH grades). High coercivity means that the magnet can maintain stable magnetism under high temperature or external interference environment, prevent magnetic attenuation, and ensure that the servo motor can still maintain efficient performance under high load or long-term operation.
High remanence improves system efficiency
Remanence (Br) is an important indicator for evaluating the magnetic properties of NdFeB magnets. The remanence of Arc Neodymium Magnet for Servo Motor's 30SH grade can reach 1080-1130 KG, while the 42SH grade can reach 1280-1320 KG. The higher remanence value ensures that the magnet provides stronger magnetic force during the magnetic field generation process, thereby improving the output efficiency of the servo motor system and reducing energy loss.
High strength and stability
The iHc Koe (magnetic field strength) of all grades is greater than 21 KA/m, with the highest being 21 KA/m (1672 Oe) for 42SH, which means that the magnet can work stably under strong magnetic field conditions, avoiding magnetic field weakening or magnet failure due to external interference. Stable magnetic force output ensures that the servo motor can maintain precise positioning and control during dynamic operation.
