Abstract

An active spindle system with an Electro-Magnetic Actuator (EMA) is developed for micromachining. The process of developing controllers for this mechatronic system requires reasonable models that expose the important dynamic effects without being excessively complicated. This paper develops a MIMO model with four inputs and two outputs based on the bond graph method. This model considers the bidirectional bearing compliance as well as the external load effect. System state space equations are produced automatically from the bond graph model. Simulations in several conditions are done in both time and frequency domain. Results from simulation and experiments are compared.
