The axial field design eliminates cogging torque and unbalanced magnetic pull that in turn helps to reduce friction lossof the bearing, vibration and acoustic noise.
If the thickness of the air gap is not constant, the magnitude of the electromagnetic forces is nonzero and is called unbalanced magnetic pull (UMP).
The influence of the unbalanced magnetic pull on the natural frequency of the rotor of the generator is studied by harmonic balance method.
As a consequence of these interactions, strong unbalanced magnetic pull forces appear between the stator and rotor, which act upon the parts of the motor bringing them into an oscillation state.
