Design and Analysis of the Novel Plate Modal Motor

Abstract:

In this paper, we demonstrated a lightweight compact motor operating at 70 ~ 100 kHz. The motor is simpler than an electric motor in structure and lower power consumption but higher speed than that of conventional peizoelectric motors. Driver for the PMM is impressively simple. A wave generator and amplifier are all that it takes to supply the piezoelectric ceramic with voltage. Finite element model was developed using ANSYS for the purpose of prediction of the resonance frequency of the vibration mode for the motor driving stator. The periodic plate modal deformation is passed on to a driving bolt, which causes it to oscillate with a movement resembling that of a turning vibrator. The rotor attached to the motor presses its tip on to driving bolt to be driven. The motor is continually being modified to enhance the performance and efficiency. It has a lot of merits such as slim shape, easy holding for motor structure and low manufacturing cost.
