System to control pressure and volumetric flow of a hydraulic medium in a hydraulic circuit forming part of automotive twin-coupled gear

摘要

An automotive twin-coupled gear is operated by a hydraulic oil system with a pump (3) powered by an electric motor (2) with a rotor driven by an electromagnetic field. The electric motor is a brushless intermittently-controlled unit. The rotor is powered by a high-speed electromagnetic field rotating at a target speed.
