3-wheeled electric tricycle Lightweight arc motor magnet Circular Arc Motor Magnet is one of the core components of arc motor, which is used to generate magnetic field to drive motor operation. It usually consists of an electromagnetic coil and a magnet. An electromagnetic coil is a coil of wire wound, usually copper or aluminum. When an electric current passes through the coil, it creates a magnetic field. The structure and shape of the electromagnetic coil can be designed according to the needs of the motor to achieve the desired magnetic field strength and distribution. Magnets are made of permanent magnet materials, usually using ferrite or Ndfeb and other materials. The role of the magnet is to enhance the magnetic field generated by the electromagnetic coil to improve the efficiency and performance of the motor. The design and manufacture of light arc magnet need to consider many factors, including motor power, speed, load requirem…
