The free-piston linear generator (FPLG) uses chemical energy from fuel to drive magnets through a stator and converts this linear motion into electric energy. Because of its versatility, low weight and high efficiency, it can be used in a wide range of applications, although it is of special interest to the mobility industry as range extenders for electric vehicles.
ATEGs allow the automobile to generate electricity from the engine's thermal energy rather than using mechanical energy to power an electric generator. Since the electricity is generated from waste heat that would otherwise be released into the environment, the engine burns less fuel to power the vehicle's electrical components, such as the ...
On the other hand, if the motor is driven as a generator, the no-load voltage between terminals is perfectly proportional to the RPM and true to the of the motor/generator. The terms K e {\displaystyle K_{\text{e}}} , [ 2 ] K b {\displaystyle K_{\text{b}}} are also used, [ 4 ] as are the terms back EMF constant , [ 5 ] [ 6 ] or the generic ...
An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators. As silicon-diode rectifiers became widely available and affordable, the alternator gradually replaced the dynamo.
A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.
Electric motor can start the engine with vehicle in gear making take-off with stalled combustion engine smooth and instantaneous. [10] 48V starter-generator can also be mounted differently and be uncoupled from combustion engine by transmission or clutch. This might allow 48V electric motor move the vehicle without starting combustion engine.

The motor–generator set may contain a large flywheel to improve its ride-through; however, consideration must be taken in this application as the motor–generator will require a large amount of current on re-closure, if prior to the pull-out torque [clarification needed] is achieved, resulting in a shut down. The in-rush current during re ...
