Ultra High Temperature Motors

Permanent magnet synchronous motor has been widely used in many fields because of its high efficiency and energy saving. However, in some special environments, such as ultra-high temperature environment in industrial production, the reliability and performance of the motor will be affected. Therefore, the high temperature resistance of PMSM is very important for its application in ultra-high temperature environment.

In ultra-high temperature environment, the permanent magnet of permanent magnet synchronous motor may be permanently damaged, which will lead to the decline of motor performance. At the same time, high temperature will also damage the insulation of the motor coil, causing the motor to malfunction. Therefore, in order to make permanent magnet synchronous motor run normally in ultra-high temperature environment, permanent magnets need to be adjusted in design, material selection and manufacturing.

The magnet of permanent magnet synchronous motor is its core component, and the thermal stability of permanent magnet material directly affects its application in high temperature environment. Therefore, when designing and manufacturing motors, permanent magnet materials with high temperature tolerance, such as NdFeB and SmCo, should be selected.

Neodymium magnet is the best-selling magnet in the market, which has extremely high magnetism. Its BHmax is more than 10 times higher than ferrite. Magnetic steel itself has excellent mechanical properties. The working temperature can reach up to 200 degrees Celsius. Powerful magnets are widely used because of their hard texture, stable performance and good cost performance. However, due to its strong chemical activity, the surface of the magnet must be treated. (such as Zn, Ni, electrophoresis, passivation, etc.).

magnets for ultra high temperature motors

Our team has a complete production process, mature technology and strict quality control, which can be customized to produce all kinds of products., Our magnets are also applied in Machinery, Audio/Video, Communication Equipment, Medical Device, Magnetic Separator, Office Automation, etc.

Neodymium magnet brands N30AH, N33AH, N35AH and N38AH are high temperature neodymium magnets. The AH series NdFeB offers exciting new options, and the working temperature is as high as 240 (while the EH series works at 200). Many factories can't customize for customers because they don't have such materials. These new brands can be used for magnetic applications at higher temperatures than before. Therefore, it is a good choice when designing new applications with working temperature as high as 240 degrees Celsius. These high-temperature neodymium magnets can also replace the more expensive samarium cobalt magnets. AH series neodymium magnets can replace samarium cobalt 5 series magnets with working temperature as high as 250 degrees Celsius.
