Vector control (motor) — Vector control (also called Field Oriented Control, FOC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors by controlling the current fed to the machine.MethodThe… … Wikipedia
Vector (molecular biology) — In molecular biology, a vector is any vehicle used to transfer foreign genetic material into another cell. The vector itself is generally a DNA sequence that consists of an insert (transgene) and a larger sequence that serves as the backbone of… … Wikipedia
