There is a rotating machine that transforms electrical energy into mechanical energy. It is called a motor. These exist in many electronic gadgets, toys, and cell phones. These motors consist of a coil of wire (usully copper) and permanant magnets. When current is sent through these coils, it interacts with the magnetic field caused by the magnets, creating torque on that coil, which in turn causes it to spin. This spinning can be used as mechanical energy to power someting. An electrical motor can also be used in reverse. This is how electricity is generated. A generator is just an electrical motor in reverse. By using an engine, falling water, or steam to turn a motor, current is created inside the spinning copper coil, which can then be transmitted along a power grid.
A generator is a machine that converts mechanical energy into electrical energy, producing electric current. It works on the principle of electromagnetic induction where a coil of wire rotating in a magnetic field creates an electric current.

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.
A machine that transforms kinetic energy into electricity is called a generator. Generators use the motion of a turbine or other mechanical device to rotate a coil in a magnetic field, creating an electric current. This process converts mechanical energy into electrical energy that can be used to power various devices.
Electrical energy is transferred to mechanical energy when an electric motor is used. The electric motor uses the electrical energy to generate a magnetic field, which interacts with other magnetic fields to produce a rotating motion, thus converting electrical energy into mechanical energy.
A shaft bearing is a low friction support device for a rotating member of a mechanical machine.
An electric sewing machine does it's work by using electricity to move the needle up and down, and rotate the bobbin. The mechanical parts of a manual sewing machine, had to be set in motion by turning a handle, or pedal. An electric sewing machine has an electric motor attached to these rotating parts, by belt or gearing and operated by a foot switch. This makes it less tiring on the arms or feet, you can keep sewing faster and longer.
The motor is electric, the hot water is typically heated by gas or electric.
The word rotor is used to refer to a rotating part of a machine. It is also a palindrome.
A machine, such as a water wheel or steam engine, that receives and modifies energy as supplied by some natural source or fuel and transforms it into mechanical work.
