China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnets come in a wide variety of shapes. While common types include circles, rings, squares, and rectangles, there are also more unique polygons, triangles, trapezoids, and rhombuses. Today, we'll introduce magnets shaped like loaves of bread.
Bread-shaped magnets, also known as motor blocks, are primarily used in the motor industry and are typically radially magnetized. Their appearance features one flat side and one curved side, closely resembling a loaf of bread, hence the name.
The accompanying image shows a standard bread-shaped neodymium magnet.
Bread-shaped magnets are typically made of sintered neodymium iron boron (NdFeB) material, though some customers opt for ferrite. The advantage of NdFeB is its ability to be machined directly without molds, allowing its curved surface to tightly conform to the rotor housing. This creates a uniform air gap magnetic field. Compared to traditional rectangular or curved magnets, bread-shaped magnets better balance magnetic and mechanical properties. This results in reduced vibration, lower noise, and higher efficiency during high-speed operation.
Regarding dimensional processing, bread-shaped magnets can be customized to non-standard specifications based on customer requirements. Standard dimensions are as follows: Width (W): 10mm to 40mm Height/Thickness (H): 3mm to 15mm Radius (R value) can be customized according to rotor or stator radii, with R10 to R60 being common values.
Bread-shaped magnets, as one of the key configurations for motor magnets, hold a significant position in high-efficiency energy-saving motors and precision motion control applications due to their unique structural design and outstanding magnetic properties.
