Robert Adams Pulsed Electric Motor Generator: Theory & Tips
An electric motor is at the same time a generator, and the generator output of a motor is the counter EMF. Now here comes the really interesting part that was an eye-opener for me: What actually moves the armature current through the armature coils is the difference between the voltage applied to the motor (Ea) minus the counter-emf (Ec).
Electric Generator
An electric generator is an electronic appliance that converts mechanical energy into electrical energy. Generators do not create electricity. Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

The schematic diagram of a M-G set is shown in the ...
Difference Between Motor And Generator, Working Principles
In a motor, the energy flow is unidirectional, moving from electrical to mechanical. Electrical energy is supplied to the motor, resulting in the generation of mechanical motion. A generator operates in the reverse direction. It converts mechanical energy into electrical energy, with the primary output being electrical power.
