Can the use of neodymium arc magnets reduce the volume and weight of motors?

The use of neodymium arc magnets can typically reduce the volume and weight of motors. This is mainly due to several reasons:
High energy product: Neodymium iron boron magnets have a very high energy product (magnetic energy density), which allows them to provide a powerful magnetic field even in relatively small volumes. This enables the use of smaller magnet sizes for the same magnetic performance.
High coercivity: Neodymium iron boron magnets have high coercivity (magnetic strength), allowing them to generate the required magnetic field intensity in smaller volumes, thereby reducing the volume and weight of magnets in motors.
Design flexibility: Arc magnets can better adapt to the structure and layout of motors, effectively utilizing space, optimizing magnetic circuit design, and reducing internal magnetic resistance in motors, thereby reducing the overall volume and weight of motors.
Therefore, the use of neodymium arc magnets typically reduces the volume and weight of motors without sacrificing motor performance. This is crucial for improving motor power density and overall efficiency.
