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.
The dynamo exists in two types, or configurations. The first, the generator, delivers only Direct Current; while the second type, the alternator delivers just AC, or alternating current. For the Dynamo to produce energy it must be turned. Water falling 1,000 feet down onto a turbines blades will spin the [attached] Generator. Steam has the same effect upon the blades of a turbine.

Operation Dynamo
Operation Dynamo was the evacuation of around 338,000 allied troops from the beaches of Dunkirk in Northern France between 28 May and 4 June 1940. They managed to escape before they were about to be surrounded by the advancing German Army.
