Commutator of the Woolrich Electrical Generator. The first electrical machine used for an industrial process was a magneto, the Woolrich Electrical Generator. [3] In 1842 John Stephen Woolrich was granted UK patent 9431 for the use of an electrical generator in electroplating, rather than batteries.
As an example, consider the use of a 10 hp, 1760 r/min, 440 V, three-phase induction motor (a.k.a. induction electrical machine in an asynchronous generator regime) as asynchronous generator. The full-load current of the motor is 10 A and the full-load power factor is 0.8.
A linear alternator is essentially a linear motor used as an electrical generator. An alternator is a type of alternating current (AC) electrical generator. The devices are often physically equivalent. The principal difference is in how they are used and which direction the energy flows.
A generator can also be driven by human muscle power (for instance, in field radio station equipment). Protesters at Occupy Wall Street using bicycles connected to a motor and one-way diode to charge batteries for their electronics [22] Human powered electric generators are commercially available, and have been the project of some DIY ...
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 lose speed and may draw a large current when power returns or the circuit-breaker is re-closed. If the speed loss is excessive (the power outage is too long), the re-closure ...
The Oliver 80 was introduced in 1938 by developing the existing Oliver Hart-Parr 80 industrial tractor for row-crop use. The 80 was equipped with a Waukesha-Oliver four-cylinder 334-cubic-inch (5,470-cubic-centimetre) engine, developing 43 horsepower (32 kW), with three or four-gear transmissions.
A black start is the process of restoring an electric power station, a part of an electric grid or an industrial plant, to operation without relying on the external electric power transmission network to recover from a total or partial shutdown. [1] Power to restart a generating station or plant may come from an on-site black start standby ...
This response in case of a synchronous generator is built-in into the design and happens without any external intervention or coordination, providing the automatic generation control and the grid operator with valuable time (few seconds) to rebalance the system [1] The grid frequency is the combined result of the detailed motions of all ...
