Magnets for High Quality Servo Motors/automotive motors/new energy car motors.

Mainly used for Pump motors/automotive motors/new energy car motor and so on.The material grade are mostly from SH to EH. According to customers requirement, we can keep the tolerance machining within +/-0.03mm. Because those magnets are used in the hard surroundings , especially like automotive with 20 years life, majority of them have the Epoxy /Al coatings that can go through more than 240h SST.

Automobile is one of the most widely used fields of neodymium iron boron. In each car, permanent magnet magnets can generally be used in 30 parts. The consumption of high-performance neodymium iron boron for each hybrid electric vehicle is approximately 2.5kg, while for pure electric vehicles, it is 5kg per vehicle. As countries have established schedules to stop using gasoline and diesel vehicles, the demand for high-performance neodymium iron boron permanent magnet materials will continue to expand in the future, as only clean energy powered automotive products are allowed.

1.How to design and select the most cost-effective magnet that meets customer needs?

Magnets are classified into different grades based on their ability to withstand temperature; According to different usage requirements, the same brand is divided into different performance levels, and different performance levels correspond to different performance parameters. In general, designing and selecting the most cost-effective magnet requires the customer to provide the following relevant information,

▶ Application fields of magnets
▶ Material grade and performance parameters of the magnet (such as Br/Hcj/Hcb/BHmax, etc.)
▶ The working environment of the magnet, such as the normal working temperature of the rotor and the maximum possible working temperature
▶ The installation method of the magnet on the rotor, such as whether the magnet is surface mounted or slot mounted?
▶ Machining dimensions and tolerance requirements for magnets
▶ Types of magnetic coating and anti-corrosion requirements
▶ Requirements for on-site testing of magnets (such as performance testing, coating salt spray testing, PCT/HAST, etc.)
