all the electrical machines can be run either as a motor or as a generator.
but dc machines, A motor can be run as generator and vice versa with little modification
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
A power switching circuit called an inverter. You could also use an electromechanical motor-generator: DC motor turning an alternator.
Type your answer here... how can you change an ac motor to a dc generator
Turn the DC generator inside out and you have an alternator .
a motor Will do work by consuming power a generator is just the opposite
You don't. Bicycle gen is dc and you're wanting an ac motor.
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
by a hand driven motor or always it is connected with dc motor.
since the physical construction of a DC motor and DC generator is the same,it can work either way.in other words,yes a DC motor can work as a DC generator(if you drive it by a primemover it will produce electricity).however its not possible with all AC motors.
Starting of the synchronous motor using the DC generator creates a magnetic field.
Such conversions are often inefficient and/or expensive. It requires an external power supply or battery charger to convert AC into DC.
