MOST SIGNIFICANT DIGITThe MSD is the digit whose position within a given number expression has the greatest weighting power [13]. |
MOTORA machine that converts electrical energy to mechanical energy. It is activated by ac or dc voltage, depending on the design [5]. |
MOTOR LOADAny device driven by a motor. Typical loads are drills, saws, water pumps, rotating antennas, generators, and so forth. The speed and power capabilities of a motor must be matched to the speed and power capabilities of the motor load [5]. |
MOTOR REACTIONThe force created by generator armature current that tends to oppose the normal rotation of the armature [5]. |
MOTOR STARTERSLarge resistive devices placed in series with dc motor armatures to prevent the armature from drawing excessive current until armature speed develops counter emf. The resistance is gradually removed from the circuit either automatically or manually as motor speed increases [5]. |
MOVING TARGET INDICATORA device that limits the display of radar information to moving targets [18]. |
MOVING-IRON METER MOVEMENTSame as MOVING-VANE METER MOVEMENT [3]. |
MOVING-VANE METER MOVEMENTA meter movement that uses the magnetic repulsion of the like poles created in two iron vanes by current through a coil of wire; most commonly used movement for ac meters [3]. |
MSDSee MOST SIGNIFICANT DIGIT [13]. |
MTDSAn abbreviation for the marine tactical data system [17]. |
