What is the main component of a rotary inverter?

The main component of a rotary inverter is a permanent magnet AC generator assembly. This assembly is critical because it serves as the primary source of alternating current (AC) that is produced from the mechanical energy supplied by the rotary system. The use of permanent magnets allows for a reliable and efficient generation of AC power, which is essential in applications where AC output is needed from a mechanical drive source.

In rotary inverters, the AC generator assembly converts the rotational motion, typically derived from an engine or another mechanical power source, into electrical energy. This conversion process is vital for providing power to systems that require AC, such as certain types of electrical loads found in aviation or other industrial applications.

The other options, while relevant in different contexts, do not represent the main component of a rotary inverter. The synchronous motor assembly can be part of a system that interacts with the inverter but does not define its core functionality. A transformer with multiple taps might be involved in voltage regulation but is not a primary component of an inverter. Similarly, a hydraulic motor system refers to a different type of mechanical power source and does not pertain to the fundamental design of a rotary inverter.
