electrical generator
Let an agent identify a generator by type and rating, explain how it works, relay safety, installation, emissions and grid connection rules from standards and regulators, and separate generators from motors, batteries and engines.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent identify a generator by type and rating, explain how it works, relay safety, installation, emissions and grid connection rules from standards and regulators, and separate generators from motors, batteries and engines.
A machine that converts mechanical energy into electrical energy by moving conductors through a magnetic field, from bicycle dynamos and portable engine-driven sets to the alternators in cars and the turbine-driven generators of power stations; generators are rated by power, voltage and frequency and are the main source of electricity supply.
What it is for: Producing electricity from mechanical motion.
It can be identify the type and rating; explain the working principle; relay safety and installation rules; compare options for backup or portable power.
Distinguishing features
Converts motion to electricity by electromagnetic induction
Synchronous or induction, AC or DC
Rated by power, voltage and frequency
Needs a prime mover
What it looks like
A rotating machine with a shaft, housing and terminals, often coupled to an engine or turbine; portable sets combine engine, generator and frame.
Physical character
output: watts to gigawatts W - from dynamos to power station units
frequency: 50 or 60 Hz - for grid machines
speed: 1500 or 3000, 1800 or 3600 rpm - for two- and four-pole grid machines
How it is recognised
Rotating machine with electrical output terminals
Nameplate with kVA or kW, voltage, frequency and speed
A motor converts electricity to motion; a battery stores energy
