Motors and generators.
Motors may be electrically powered or spring powered. When steam or fuel powered they are usually referred to as engines.
Generators may be motor or engine driven, water driven or wind driven, and even animal driven.
Waterwheels, turbines and windmills would also be rotating machines.
There are rotating machines that cycle over and back, as opposed to a continuous rotation; an example is the rotary solenoid.

What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
How rotating magnetic amplifier work?
what does it mean by rotating amplifier and how it works?
All machines are constructed from six machines?
All machines are constructed from six simple machines
Is there any windage loss in transformer?
In this context, 'wind', in 'windage', is pronounced as 'wind' -as in 'breeze' or 'gale'. 'Windage means air-resistance, and this only applies to rotating machines, such as generators and motors, whose rotors have to overcome air-resistance (windage) as they rotate. As transformers have no moving parts, they are NOT subject to windage loss!
What is the rotating drum attached to?
an attached pen
Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
What is axial alignment in rotating machines?
Shaft center to center
What is 3 concentric rotating shafts?
Three concentric and rotating shafts would be known as a contra-rotating device. Currently, several machines like these are being designed, according to the US Patent Office.
Is all electricity made in the same way?
No, it can be made by rotating machines or by solar panels. Rotating machines can be driven by engines or by the wind. Engines can be water turbines (hydroelectric), steam turbines (coal/oil), gas turbines or petrol or diesel.
What chapter of BS 7671 covers rotating machines?
Ah, the beautiful world of electrical installations! In BS 7671, the chapter you're looking for is Chapter 42. This chapter specifically focuses on the installation of electrical machines, including rotating machines. Remember, each chapter in the regulations is like a happy little tree adding to the big picture of electrical safety.
What are bad things about wind turbines?
turbine is a one that is rotating motor which delivers the energy to machines
In which chapter of BS 7671 would you find reference to rotating machines?
Well, darling, if you want to find information on rotating machines in BS 7671, you better flip to Chapter 41. That's where you'll get all the juicy details on those spinning contraptions. So, go ahead and give it a whirl!
Why are transformer more efficient than a rotating electric machine?
Transformers inherently do not have frictional losses, but transformers and rotating machines perform completely different functions, so I'm not sure it is fair to compare them. Transformers are used to transform electric energy (the input is electric energy, and the output is electric energy). Rotating machines either take electric energy and convert it to mechanical/kinetic energy, or take kinetic energy and convert it to electric energy.
What is slot harmonics?
in rotating machines the air gap permeance in front of the slots changes with rotating rotor that it change flux in air gap and affect the voltage and current in machine. baradaran from jondishapour university iran
What is subtrnsient?
These terms appear in the calculation of fault currents. Common sources of fault currents are rotating machines, i.e., motors and generators.
What are the benefits of rotating unions?
They assist machines in the transfer process of air, steam, water, hot oil, hydraulic fluids and industrial gases.
What is the difference between drilling and boring machines?
Drilling machines are used to create holes in a workpiece, while boring machines are used to enlarge or smooth out existing holes. Drilling machines typically use rotating drill bits to create holes, while boring machines use single-point cutting tools to enlarge existing holes to precise dimensions.
