"C" Terms
COMMUTATION. The act of a commutator in converting generator output from an ac voltage to a dc
voltage.
COMMUTATIVE LAW. In Boolean algebra this law states that changing the order of the terms in an
equation will not affect the value of the equation. Example: A + B = B + A; A • B = B • A.
COMMUTATOR. A mechanical device that reverses armature connections in motors and generators at
the proper instant so that current continues to flow in only one direction. In effect, the commutator
changes ac to dc. Motor Vendors
Motor Commutator
CompactPCI. Compact Peripheral Component Interface. An industrial version of the PCI standard [Peripheral Component Interface]. CompactPCI uses the Euro board format/size, but uses the same electrical standard as the consumer PCI interface bus. CompactPCI Bus.
COMPANDER. An acronym for COMpressor-exPANDER. A circuit that compresses and then expands the signal in amplitude.
COMPENSATING WINDINGS. Windings embedded in slots in pole pieces, connected in series with the armature, whose magnetic field opposes the armature field and cancels armature reaction.
COMPENSATION. The process of overcoming the problems associated with high frequencies in an amplifier.
COMPLEMENT. A number or state that is the opposite of a specified number or state. The negative of a number is often represented by its complement.
COMPLEMENTARY (SECONDARY) COLORS OF LIGHT. The colors of light produced when two of the primaries are mixed in overlapping beams of light. The complementary colors of light are magenta, yellow, and cyan.
COMPLEMENTARY LAW. In Boolean algebra this law states that the logical addition of a quantity and its complement will result in 1 and the logical multiplication of a quantity and its complement will result in a product of 0.
COMPLEMENT NUMBER. A number that when added to another number gives a sum equal to the base of the number system of operation. For example, in the decimal number system, the complement of 1 is 9.
COMPLEX WAVE. A waveform other than a sine wave. A wave that is produced by combining two or more pure tones at the same time.
COMPLIANT PIN. A pin used with a Printed Circuit Board [PCB] as an interconnect. The pin is press-fit and solder-free. In most cases the pin[s] are the board mount side of a connector. Read more on Compliant Pins
COMPOUND-WOUND MOTORS AND GENERATORS. Machines that have a series field in addition to a shunt field. Such machines have characteristics of both series- and shunt-wound machines. [Manufacturers of Motors]
