Abstract
In a motor-generator configured to use no flywheel connection to an internal combustion engine, an inner stator is provided. An outer rotor is arranged to surround the inner stator. The outer rotor is connected to the internal combustion engine without a flywheel and is configured to reduce noise due to at least one of torque ripples of the internal combustion engine and rotational fluctuations of the motor-generator.
