[′dī·nə‚mō·dər]
(electricity)
A rotating electric machine having two or more windings on a single armature containing a commutator for direct-current operation and slip rings for alternating-current operation; when one type of power is fed in for motor operation, the other type is delivered by generator action. Also known as rotary converter; synchronous inverter.

Under deceleration, the motor-generators apply braking force in combination with traditional mechanical brakes to harvest energy, which is transferred via inverter (AISIN AW at the front, DENSO at the rear) to the NISSHINBO super-capacitor.
Fractional horsepower motors (fractions of one horsepower) account for the majority of motor and generator production; followed by integral horsepower motors (multiples of one horsepower); 'prime mover' generators (powered by prime movers like diesel or steam engines); and motor-generator sets.
Based on an integrated motor-generator flywheel that stores kinetic energy in its constantly spinning, quiet, low-friction steel disc, the CleanSource DC provides energy to the UPS that eliminates more than 94 percent of power disturbances on its own or provides sufficient ride-through to allow time for an engine generator-set to start up and supply continuous power for essential systems.
Combining a rugged steel flywheel with solid-state power electronics, Active Power's CleanSource technology incorporates a proven flywheel motor-generator that stores kinetic energy in its constantly spinning, quiet, low-friction steel disc.
Bender said: "What we have built is a system that combines a lighter, smaller bore-loaded flywheel rotor with a practical and cost-effective 20kg ironless motor-generator, meaning that everything else in the system can be lighter and smaller -- the cabinet, the framework, the floor loading, etc.
Active Power's CleanSource products are currently UL Listed under the Motor-Generator Category.
The powertrain consists of four major elements: a turbogenerator, a flywheel motor-generator, an electric drive motor and an electronic control system.
