DC Motor Torque
Torque is defined as that force which tends to produce and maintain rotation. The function of torque in a DC
DC Motor Theory
DC motors are widely used to drive various equipment. The speed and torque produced in a DC motor depends on
Compound Generators
Series-wound and shunt-wound generators have a disadvantage in that changes in load current cause changes in generator output voltage. Many
Series-Wound DC Generators
When the field winding of a DC generator is connected in series with the armature, the generator is called a
Shunt-Wound DC Generators
When the field winding of a generator is connected in parallel with the generator armature, the generator is called a
DC Generator Internal Losses
There are four internal losses that contribute to lower efficiency of a DC generator. Copper losses Eddy-current losses Hysteresis losses
DC Generator Theory
DC generators are widely used to produce a DC voltage. The amount of voltage produced depends on a variety of
DC Machines Construction
Direct current machines are energy transfer devices. These machines can function as either a motor or a generator. DC motors
DC Machines Terminology
DC Machines Terminology Terminal Voltage Terminal voltage, as applied to DC generators, is defined as the voltage that can be
Battery Hazards
Because batteries store large amounts of energy, there are certain hazards that are associated with battery operation. These hazards must
