Dynaflow (Buick) The Dynaflow was an automatic transmission used in various forms in Buick cars by the General Motors Corporation from 1947 until 1963. The transmission initially used a five-element torque converter, with two impellers and two stators, as well as a planetary gearset that provided two forward speeds plus reverse.

It is designed for service in vehicles up to 4000 lb (1814 kg) GVWR and in service was mated to a selection of final drive ratios 3.42:1, 3.73:1, or 3.91:1 depending on the carline. The 5L40-E had been designed for 1.8–3.6 L engines with a maximum of 250 ft·lbf (340 N·m) of torque.
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 .
A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...
So (as an example) a 10 HP motor is most efficient when driving a load that requires 7.5 HP. [104] Efficiency also depends on motor size; larger motors tend to be more efficient. [ 105 ] Some motors can not operate continually for more than a specified period of time (e.g. for more than an hour per run) [ 106 ]
In 2021, Allison expanded the range with the 100S (a single-motor variant of the 100D, with continuous and peak power output of 212 and 324 kW (284 and 434 hp), respectively and a maximum 23,500 N⋅m (17,300 lbf⋅ft) of torque) and the 130D (a variant of the 100D with a higher 13 t (29,000 lb) GAWR for the European and Asia Pacific markets).
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
