An electricity generator, a dynamo-electric machine.
An electric generator which produces alternating current through mechanical means.
(figuratively) An energetic person.
‘That new Vice President of Marketing is a real dynamo; sales have already gone up this quarter.’;
An electric generator or dynamo for producing alternating currents.
A dynamo-electric machine.
an old term for an electric generator that produces alternating current (especially in automobiles)
generator consisting of a coil (the armature) that rotates between the poles of an electromagnet (the field magnet) causing a current to flow in the armature
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.
A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter.
