AFPM(Axial Flux Permanent Magnet) Motor
AFPM Technology
Main magnetic flux flows in the axial direction.
- RFPM Torque=
- Determined by axial stack length L and rotor outer diameter D
- AFPM Torque=
- Proportional to the effective cross-sectional area of the air gap, 〖𝐷_𝑜𝑢𝑡〗^2−〖𝐷_𝑖𝑛〗^2
(Determined by the length of the inner and outer diameters, regardless of the axial length)
AFPM Characteristics
Advantage of size and weight due to the high level of torque generation area per volume
Effectively generated high torque achievable usefully in the space of relatively large diameter and small thickness
