DUAL REDUNDANT MOTOR/ GENERATOR FOR AN ENGINE

摘要

An exemplary electrical system may include a power plant and a dual motor/generator assembly coupled to each other. The power plant may be a gas turbine engine, and may be operable to provide motive power. The dual motor/generator assembly may include a first motor/generator and a second motor/generator operatively coupled to a common gear shaft, and a gear box configured to couple the first motor/generator and the second motor/generator to the power plant. The first motor/generator and the second motor/generator may be operable to selectively provide power to or extract power from the power plant. The dual motor/generator assembly may be configured such that the first motor/generator and the second motor/generator may operate together at part loads, or individually as a main and a redundant, backup to the other.
