Sm2co17 SmCo Arc Magnets for Motors

Samarium Cobalt as Second Generation Rare Earth Permanent Magnet, which is made of samarium, cobalt and other rare earth metal materials, dissolved into alloy, crushed, pressed and sintered. As part of the rare earth group of permanent magnets, SmCo magnets typically fall into two families of materials. They include rare earth SmCo5 and Sm2Co17, and are commonly referred to as 1: 5 and 2: 17 materials.

Sm2co17 SmCo Arc Magnets for Motors

Samarium cobalt magnet is mainly formed by the metal samarium, cobalt and some other rare earth elements of the permanent magnet.It has a high magnetic energy product, super low temperature coefficient,and the operating temperature can up to 300 ℃.At the same time, it has a strong corrosion resistance and oxidation resistance. Therefore, SmCo magnetic steel usually does not need to be electroplated, and is widely used in motors, meters, sensors, engines, radar and for other high-tech fields.

SmCo Arc Magnet is a common shape of SmCo Rare earth magnets. SmCo Magnets are perfect for high temperature application, as they can work properly at 250-300 °C. We provide SmCo Arc Magnets for various applications.

SmCo Arc Magnet for generator and electric motor

Compared to the traditional motor, rare-earth magnet coreless motor with high efficiency, light weight, small size, good speed control, reliability, etc. can be widely used in wind power, electric vehicles, industrial motors, and other fields. In the low-carbon energy saving background, samarium cobalt market is very large. Currently, in Japan and Europe and other countries use about 98% of the air-conditioning inverter air conditioner, but China seldom uses. the inverter air conditioner has comfortable, energy-saving features will

become a trend in the future.
