Direct torque control — (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors. This involves calculating an estimate of the motor s magnetic flux and torque based on the measured… … Wikipedia
Direct methanol fuel cell — Direct methanol fuel cells or DMFCs are a subcategory of proton exchange fuel cells in which methanol is used as the fuel. Their main advantage is the ease of transport of methanol, an energy dense yet reasonably stable liquid at all… … Wikipedia
Direct Digital Control — (DDC) refers to the ability to control HVAC (Heating, Ventilating, and Air Conditioning) devices via microprocessors containing a software performing the control logic. DDC receive analog and digital inputs from the sensors and devices installed… … Wikipedia
Direct digital control — (DDC) is the automated control of a condition or process by a digital device (computer).[1][2] A very early example of a DDC system meeting the above requirements was completed by the Australian business Midac in 1981 1982 using R Tec Australian… … Wikipedia
Direct drive mechanism — A Direct drive mechanism is one that takes the power coming from a motor without any reductions (such as a gearbox). Contents 1 Advantages 2 Disadvantages 3 Applications 3.1 High speed … Wikipedia
Doubly fed electric machine — Doubly fed electric machines are electric motors or electric generators that have windings on both stationary and rotating parts, where both windings transfer significant power between shaft and electrical system. Doubly fed machines are useful… … Wikipedia
High voltage — The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X… … Wikipedia
Doubly-fed electric machine — Doubly fed electric machines (i.e., electric motors or electric generators) belong to a category of electric machines that incorporate two multiphase winding sets of similar power rating that have independent means of excitation. As a result,… … Wikipedia
High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
Gramme machine — A Gramme machine or Gramme magneto. A Gramme machine, Gramme ring, Gramme magneto, or Gramme dynamo is an electrical generator which produces direct current, named for its Belgian inventor, Zénobe Gramme, and was built as either a dynamo or a… … Wikipedia
