Axial Gap Type Motor
Axial-gap motors use an axial magnetic flux to rotate a disc-shaped rotor and stator facing each other. The advantage is that it can be constructed thinner than a radial-gap motor, and if properly designed, a high torque can be obtained relative to the magnetic flux density. The use of axial-gap motors expands to a wide variety of applications, including automobiles, and can meet market requirements with a design that takes advantage of its unique structure.
The JMAG Advantage
- Fast 3D electromagnetic simulation
- Mesh modeling that accurately captures short cogging torque periods
- Geometry modeling to capture AC losses in coils and eddy current losses in magnets
- Versatile material modeling function, such as evaluating core losses in soft magnetic composites
- Efficiency mapping function that accounts for these detailed losses
- Total evaluation can be made of the temperature rise due to loss and noise/vibration due to electromagnetic force
