Contact-free Magnetic Clutch Applied for Flywheel Cell System

Abstract

A TDOF (Two Degrees of Freedom) Servo Gap-Retained Mechanism (SGRM) is proposed and verified by experiments. It consists of a flywheel and an Intelligent Posture Tracking System (IPTS). The flywheel is regarded as the tracking objective of the IPTS. The IPTS is mainly composed by an intelligent disc and two pairs of Hybrid Magnetic Actuators (HMAs). The posture of the intelligent disc is controlled by the magnetic forces induced by the HMAs to retain a constant gap with respect to the eccentric flywheel. Since the HMA is highly nonlinear, a Feedback-Linearized Sliding Mode Control (FLSMC) is synthesized to account for system parameter nonlinearities. The proposed SGRM is part of the flywheel cell system. When the MGU (Motor/Generator Unit) in flywheel cell operates at idle mode, the shaft of flywheel will be separated from MGU in order to avoid the energy loss of the flywheel by the back EMF induced by the magnetic field of MGU. The shaft of flywheel and MGU still need to maintain synchronous power transmission so that a contact-free clutch has to be equipped. The role of SGRM in a flywheel cell is to ensure the centerline of the flywheel properly is aligned with the magnetic clutch. Intensive experimental simulations are undertaken to verify the feasibility of the proposed SGRM and FLSMC.
