Another term commonly used for a rotor is what?

The term "armature" is commonly used in the context of electrical machines, particularly in motors and generators. In these devices, the rotor is the rotating part that can produce mechanical power or be influenced by magnetic fields. The armature typically refers to the component that carries current and is situated within the magnetic field, which generates torque in electric motors or induces voltage in generators. Understanding the relationship between the rotor and armature is crucial in the context of refrigeration and air conditioning systems where electrical motors may be employed to drive compressors and fans.

In contrast, the other terms mentioned do not specifically refer to the rotor. The stator is the stationary part of an electric machine, consisting of windings that create a magnetic field. The magnet usually refers to a permanent magnet or electromagnet within the assembly, while the drive shaft is a part connecting the rotor to the work that it drives, not the rotor itself. Thus, "armature" is the term that accurately identifies another name for the rotor in relevant applications.
