Micro-motors based on MEMS technology are recently researched and developed world-wide. This paper presents design, simulation of a micro-motor using V-shaped electro-themal actuator. This motor has cover diameter of 2.4mm, can operate with minimum applying voltage Umin = 19V and driving frequency ranging from 1 to hundreds Hz. Advantages of this motor are lower driving voltage, simple control and batch fabrication based on bulk-micromachining technology.
