what is rotary inverter?

Question

for my assignment

Answer 1

There are many sizes, types, and configurations of rotary inverters. Such inverters are essentially ac generators and dc motors in one housing. The generator field, or armature, and the motor field, or armature, are mounted on a common shaft which will rotate within the housing. One common type of rotary inverter is the permanent magnet inverter.

A rotary converter does provide full rated three phase
power to run your equipment at full power but is more
expensive to purchase. This allows you to maintain
the full rated horsepower of the motor being used.
Rotary converters are always the best choice over
a static converter, simply because of the loss of
horsepower using a static and the advantage of
having full three phase voltage for other equipment
if needed. Purchasing a rotary converter that uses
"voltage sensing" to start the converter is not a good
way to go either. These circuits will cause the starting
relay to kick back in when you have a power fluctuation
or a heavy load is applied to the converter. This will cause the starting circuit to blow the capacitors. New technology with solid state electronic circuits prevent this from happening. Voltage sensing was used years ago before the new solid state electronics was available.

Answer 2

"Rotary Inverter:
In a rotary inverter, DC electricity input powers a DC motor that turns
an AC generator. Rotary inverters are reliable and produce a pure
sine-wave output. These inverters have automatic load demand: they
begin operation once a load is activated, and shut down when the load
is removed. Disadvantages of a rotary inverter are lack of frequency
control, low surge capability (50% above maximum rating) and lower
efficiency (50% to 80%). Rotary inverters are not as common as
electronic inverters."

Answer 3

A rotary converter is a type of electrical machine which acts as a mechanical rectifier or inverter. It was used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification.

Answer 4

it simply invert the rotary
