Four wool spinning machines driven by belts from an overhead lineshaft (Leipzig, Germany, circa 1925) The belt drives of the Mueller Mill, model and reality, in motionA line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century.
English: Diagram of revolving-field single phase generator with four poles. As the rotor turns, the lines of force at fours poles are cut by the coils inducing current. The output from four coils are "in phase".
This large belt-driven high-current dynamo produced 310 amperes at 7 volts. Dynamos are no longer used due to the size and complexity of the commutator needed for high power applications. A coil of wire rotating in a magnetic field produces a current which changes direction with each 180° rotation, an alternating current (AC).
[4] [26] A manual fuel shut-off valve is also supplied, [4] and some also have a manual throttle. [4] Although the Zenith Model A carburetor was fitted to the engines in the vast majority of Ford Model A cars (reportedly to 3.5 million of the approximately 4.8 million built [27]), it was not the only carburetor used. Another 19 brands were ...
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 ...

The drawback of the Krämer drive is that the machines need to be overdimensioned in order to cope with the extra circulating power. This drawback was corrected in the Scherbius drive where the slip power is fed back to the AC grid by motor generator sets. [8] [9] The rotating machinery used for the rotor supply was heavy and expensive.
