A linear motor based on an Ishaped stator was proposed in this paper. The 1st asymmetric longitudinal mode and 2nd asymmetric inplane bending mode of the stator were employed as the working modes, four bulges on the sides of the stator were used as the stator’s driving ends which pushed the slider with each two of them in opposite angle. The principle of the motor was discussed. An FEM model for the stator was built to simulate the dynamic characteristics of the motor by the modal analysis and transient analysis. The assembly of motor with Ishaped stator is completed. The amplitude of the stator in the z and y directions were 1 μm and 2 μm respectively when the bending vibration excitation voltage was 50 V and the longitudinal excitation voltage was 250 V. This motor is expected to have a greater power and speed, and has a good application prospect.
