A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
The sequence of events is similar for manual or automatic synchronization. The generator is brought up to approximate synchronous speed by supplying more energy to its shaft - for example, opening the valves on a steam turbine, opening the gates on a hydraulic turbine, or increasing the fuel rack setting on a diesel engine.
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
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 ...
Set sizes range from 8 to 30-kW (also 8 to 30-kVA single phase) for homes, small shops, and offices, with the larger industrial generators from 8-kW (11 kVA) up to 2,000-kW (2,500-kVA three phase) used for office complexes, factories, and other industrial facilities. A 2,000-kW set can be housed in a 40 ft (12 m) ISO container with a fuel tank ...
A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940–1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox is that the gear shift lever allowed the driver to "pre-select" the next gear, usually with the ...
TREMEC engineers have recommended Texaco-Havoline Dexron III/Mercon Non-Synthetic ATF. There has been a significant amount of confusion regarding the proper capacity and proper type of ATF for the TR-3650 which may have a correlation with a rather large number of complaints about notchy shifting, shift "nibbling", noisy synchros, and grinding gears.
Manual – the driver has to perform each gear change using a manually operated clutch; Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load; Basically there are two types of engine installation:
