Motor Magnetic Tiles: Tile-shaped Magnets Used in Permanent Magnet Motors

Magnetic tiles of motor (MTM) are tile-shaped magnets used in permanent magnet motors. They are a type of permanent magnet and are primarily used in permanent magnet DC motors in new energy vehicles and industrial machinery. They replace the excitation coils in traditional electromagnetic motors, creating a constant magnetic potential source.

These products can be categorized by material: ferrite, alnico, and neodymium iron boron. NdFeB MTs have a magnetic energy product 5-12 times that of ferrites, a coercive force exceeding 859 kA/m, and an operating temperature range of -20°C to 220°C. Mounting methods are categorized by motor speed: low-speed models use AB adhesive bonding and plastic wrapping, while high-speed models use a stainless steel sleeve for enhanced stability. Adjustable fixtures are used in the production process to ensure consistent magnetic properties after magnetization. Adjustable shield spacing allows for precise positioning of the MTs to prevent misalignment of magnetic field lines.
