Air gap is one of the important factors which affect the general performances of linear synchronous oscillatingmotor, thus to seek for a rational shape of air gap is a key point in motor design.
A linear ultrasonic motor was put forward. Elliptical motions of the surface points of the stator are generated by the superposition of longitudinal and bending modes of the oscillating structures.

This is simply the motor armature oscillating at the speed control's 2500hz rate and is quite normal.
