using dc motor as generator

Direct Current (DC) Generators | How it works, Application

Direct Current or DC generators are devices that convert mechanical energy into direct current electrical energy. This is achieved through the principles of electromagnetic induction, a concept first discovered by scientist Michael Faraday in the early 19th century. He demonstrated that a change in the magnetic field within a closed …

Choosing the best DC motor to use as a generator

A brushed DC motor will generate voltage even at low RPM. Obviously, it produces DC. A downside of such a motor is that it requires periodic maintenance, related to brush wear. If the DC motor does not have permanent magnets, then it may require an external source of power to start current in the "field" winding.

DC Motor as a Generator Voltage and Current

That means the current is (111 W)/ (24 V) = 4.6 A. The winding resistance is then (11 W)/ (4.6 A)² = 518 mΩ, which is dropping (11 W)/ (4.6 A) = 2.4 V. That means the back EMF at 60 Hz is 21.6 V, or 360 mV/Hz. If you were to drive this motor mechanically at 40 Hz, it would look like a 14.4 V source with 518 mΩ in series.

DC motor as a generator

An unloaded DC motor with a certain applied voltage will generate a back emf that is about 90 % of the applied voltage. A (red) LED requires about 1.7 V to start to light. So, if you apply 2 V to the motor, it will (internally) generate about 1.6 V -- nearly enough to light the LED. If you manually rotate it, you would need to reach that speed ...
