take two dc motors..................... connect the spindle of 1 motor to a hollow pipe so that the pipe should also rotate when the motor is given dc current (one can take an empty pen refill for that).... now fix the spindle of another motor to the other end of the hollow pipe...... the two terminals of the 2nd motor is now the terminals of the dynamo which will generate dc current........

How does bridge rectifier control a DC motor?
give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
A machine for making electricity?
Generator or dynamo
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What are uses of bidirectional dc motor?
6V dc motor
What is the principle and working of dynamo?
convert mechanical energy to electrical energy
Can a DC dynamo act as a DC motor?
Yes it can and the otherway aroud a DC motor can be used as a dynamo
Difference between ac dynamo and dc dynamo?
1. AC Dynamo has full rings whereas DC Dynamo has split rings. 2. AC Dynamo produces alternating current whereas DC Dynamo produces direct current. 3. IN AC DYNAMO, CURRENT KEEPS CHANGING EVERY HALF OF A CYCLE WHEREAS IN DC DYNAMO, CURRENT FLOWS IN SAME DIRECTION.
Can electricity be regenerated by connecting electric motor to a dynamo?
The question is mine......take one dynamo and a motor (both of them are DC).. If The Dynamo is 12v and the motor is 9v...and connect together.....means the rotating shaft of a motor is connecting using a belt then the other end connected to the rotating shaft of the dynamo ......connect the wire parallel......let start... take a cotton thread of 15 cm ...then round the thread on dynamo rotating shaft the pull it....the current from dynamo flows to motor that action make the motor rotates but not constant.....
Can a 9 volt motor rotate 9 volt dynamo?
Are you going to use the 9-volt motor as a dynamo, and the 9-volt dynamo as a motor? Yes, the motor can rotate the dynamo because DC motors and DC generators are actually the same thing--they just apply power to the terminals of a motor to make it turn, and turn the shaft of a generator to make power appear at the terminals. Having said that, if you're going to try to connect the shaft of a 9v motor to the shaft of a 9v dynamo, and use the dynamo to power the motor so as to create a perpetual motion machine...that won't work. The motor wastes a little bit of energy, as does the dynamo. It is possible to build a device that uses a motor to drive an alternator, which is the AC version of a dynamo. You power the motor from the AC grid, and power something that's very sensitive to noise on the line from the alternator. This is called a Motor Generator set, and it's how they powered Cray-1 supercomputers.
Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
What is a DC generator the same as?
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.
If you crank the shaft of a dc motor manually will the motor become a dc generator?
It depends on both the wiring of the motor and what if any residual magnetic field remains in the field windings. If there is some residual field, you will get some volts, but not many. If the motor has permanent magnets, it is effectively a dynamo.
How do you convert a DC motor to a generator?
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
Is dynamo an AC generator?
DC generator
What is the highest efficeincy of a dc dynamo?
93%
Which is used to convert DC to ac?
A power switching circuit called an inverter. You could also use an electromechanical motor-generator: DC motor turning an alternator.
Why ac drive convert ac voltage in dc?
It is done to control the speed of the motor.
