Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[ 1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...
Single-phase generator. Single-phase generator (also known as single-phase alternator) is an alternating current electrical generator that produces a single, continuously alternating voltage. Single-phase generators can be used to generate power in single-phase electric power systems. However, polyphase generators are generally used to deliver ...
Horsepower. One imperial horsepower lifts 550 pounds (250 kg) by 1 foot (30 cm) in 1 second. Horsepower ( hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
Lycoming O-435. The Lycoming O-290 is a dual ignition, four-cylinder, air-cooled, horizontally opposed aircraft engine. It was first run in 1939, and entered production three years later. A common variant of the type is the O-290-G, a single ignition model which was designed to drive a generator as part of a ground power unit .
As an example, a 250 kVA motor generator operating at 300 ampere of full load current will require 1550 ampere of in-rush current during a re-closure after 5 seconds. This example used a fixed mounted flywheel sized to result in a 1 ⁄ 2 Hz per second slew rate. The motor–generator was a vertical type two-bearing machine with oil-bath bearings.
Jaguar XJ-S. The Jaguar E-Type, or the Jaguar XK-E for the North American market, is a British front mid-engined sports car that was manufactured by Jaguar Cars Ltd from 1961 to 1974. Its combination of exceptional aesthetics, advanced technologies, high performance, and competitive pricing established the model as an icon of the motoring world.
The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz). The rotating parts of a turbo generator are subjected to high mechanical stresses because of the high operation speed.
