Document Summary
Generator: a machine that converts mechanical energy into electrical energy. Electricity is produced from magnets whirling inside coils of wire in the generator core. Armature: the moving part of a magnetic device consisting of one or more coils that are electrically connected to create the rotatable section of a generator. Slip rings: a slip ring is a method of making an electrical connection through a rotating assembly, commonly found in electrical generators. Brushes: conducts current between rotating and stationary parts of a generator or motor. Commutator ring: a single ring that is divided in half, with each half connected to one end of the armature wire. Motor: an alternating current motor in which the primary winding on one member (usually the stator) is connected to the power source. A secondary winding on the other member (usually the rotor) carries the induced current. There is no physical electrical connection to the secondary winding; its current is induced.
