From the perspective of green and sustainable development, permanent magnet motor can reduce energy loss and meet the requirements of sustainable development through the reasonable selection and utilization of permanent magnet materials, the design of motor structures, and advanced transmission control technology.
Permanent magnets serve as key components in various applications, including generating mechanical energy, converting electrical energy into mechanical energy, and establishing magnetic fields in medical equipment like magnetic resonance imaging (MRI) machines and data storage devices (hard disk drives) (Cui et al., 2018).
Provided by the Springer Nature SharedIt content-sharing initiative Permanent magnets constructed from metal ions and organic linkers using molecular design principles could bring transformative advances in areas such as energy conversion, transportation, and information storage.
In an ideal permanent magnet, a large remanent magnetic flux (B r) must be maintained in the absence of a magnetic field. This is achieved by having a large resistance to demagnetization (H c or intrinsic coercivity H ci).
The high energy consumption and greenhouse gas emissions associated with rare earth mining and REO processing are also a concern for the sustainability of the energy transition using downstream products, such as permanent magnets (Binnemans et al., 2013; Kullik, 2019).
