The poles can be varied at a ratio of 1:2 and thus the speed can be varied at 2:1. [ 7 ] [ 8 ] [ 9 ] Normally, the electrical configuration of windings is varied from a delta connection (Δ) to a double star connection (YY) configuration in order to change the speed of the motor for constant torque applications, such as the hoists in cranes .
The theoretical distinction between a marquess and other titles has, since the Middle Ages, faded into obscurity. In times past, the distinction between a count and a marquess was that the land of a marquess, called a march, was on the border of the country, while a count's land, called a county, often was not. As a result of this, a marquess ...
The etymological heir of the margrave in Europe's nobilities is the marquis, also introduced in countries that never had any margraviates, such as the British marquess; their languages may use one or two words, e.g. French margrave or marquis. The margrave/marquis ranked below its nation's equivalent of "duke" (Britain, France, Germany ...

The AOD (automatic overdrive) is a four-speed automatic transmission, with the 4th gear as overdrive. Introduced in 1980, it was Ford 's first four-speed automatic overdrive transmission. The gearset design is based on the Ford "X" automatic transmissions used during the 1950s, '60s, and '70s.
While there were some cosmetic differences between E-unit models, the major line of development was technological, and largely that of increasing power. The first model, the EA/EB, was rated at 1800 hp (1300 kW), then the E3 was rated at 2,000 hp. The last model, the E9, was rated at 2,400 hp (1800 kW).
[2] [3] Once started at synchronous speed, the motor can operate with sinusoidal voltage. Speed control requires a variable-frequency drive. High-powered SynRMs typically require rare-earth elements such as neodymium and dysprosium. However, a 2023 study reported the use of a dual-phase magnetic laminate to replace them.
The British Rail Class 77, also known as Class EM2, is a class of 1.5 kV DC, Co-Co electric locomotive. They were built by Metropolitan-Vickers in 1953–1954 for use over the Woodhead Line between Manchester and Sheffield.
