Design and Performance Evaluation of Modular Electro-Mechanical Actuator

Abstract:

This article is dealing with a modular electro-mechanical actuator (EMA). Modular EMA consists of harmonic reducer, servo motor, electric brake, multi-turns absolute encoder, drive, network board. There are various modular EMAs in the market. Most of them are used for toys and educational device. In this research, we are more focused on an industrial high power (400W) modular EMA. All of components are designed and fabricated as hollow shaft type module for applying an industrial robotic system in the future. The robot which is linked to the modular EMA is easily able to assemble and disassemble or reconfigure it. We try to implement a modular EMA and this tries to be verified through an experiment.
