- Three-Phase Systems in Power Applications - True or False
6.
A balanced load is one in which all the impedances are equal.
7.
The term squirrel-cage applies to a type of three-phase ac generator.
8.
A simple two-phase generator consists of two conductive loops separated by 90°, rotating in a magnetic field.
9.
An alternator is an electromechanical ac generator.
10.
The stator is the rotating assembly in a generator or motor.
Answer: Option
Explanation:
The two main parts of a generator or motor can be described in either mechanical or electrical terms:
Mechanical:
Rotor: The rotating part of an electrical machine
Stator: The stationary part of an electrical machine
Electrical:
Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo the armature windings generate the electric current. The armature can be on either the rotor or the stator.
Field: The magnetic field component of an electrical machine. The magnetic field of the dynamo or alternator can be provided by either electromagnets or permanent magnets mounted on either the rotor or the stator.
