【Overview】What is an axial gap motor?

■What is an Axial Gap Motor? An axial gap motor is a high-efficiency, high-torque electric motor that has a structure where the magnetic flux flows in the axial direction. The stator and rotor are arranged in a disk shape facing each other, and the magnetic flux flows in the axial direction, exhibiting performance characteristics different from conventional radial motors. ■Principle Structure In an axial gap motor, the stator coil and rotor magnet are arranged in a planar configuration, and torque is generated by the flow of magnetic flux in the axial direction. This structure allows for the concentration of magnetic flux density and the expansion of the torque generation area, achieving high output while remaining compact. ■Differences from Radial Motors Radial motors are highly versatile, excelling in manufacturing costs and design flexibility, but due to their structure, they tend to be thicker and have limitations in cooling and torque density. In contrast, axial gap motors feature a thin design, high torque, and high efficiency, making them ideal for applications in special vehicles, compact mobility, and robotics where space constraints are present. Particularly in applications requiring both lightweight and high output, axial motors demonstrate significant advantages.
