The previous work of Laumeister at GE on the experimental Delta electric car that debuted in 1968 helped pave the way for the production of the Elec-Trak. [2] Despite the limited production and availability of the electric tractors, many Elec-Traks are still in use today [ 3 ] and have a cult following among tractor and electric vehicle ...
With Ford's withdrawal from F2 in the mid-1970s, Hart began to concentrate on building their own designs. The first engine to bear the Hart name alone was the twin-cam, four-cylinder Hart 420R F2 unit, which appeared in 1976 and powered race-winning cars until the end of the decade. In 1978, the Toleman team agreed to a partnership program ...

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.
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.
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 ...
An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...
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 ...
