I work with electricity frequently enough and I have a motor that I want to use as a generator/alternator. Its a universal motor so it can be run on AC or DC. Currently I can't find my multimeter and I am having problems finding a answer through searching. So I need to know, when I spin a universal motor am I creating alternating current that I will need to add a rectifier to so I can run a DC component...or am I creating DC? I ask because I have a motorized bike and I just found a sprocket drive motor and I want to use it as a dynamo for lighting, and I want to rig it to DC battery storage as well. Or if you have ideas for circuitry on my specific project that would be even better!
Hi A universal motor is most often a series connected DC motor. therefore it will generate DC voltage. You might attempt to rewire it as a shunt generator which will give you a more consistant output voltage. Series generators have highly variable output voltage depending on load. It would be difficult to get it to work against the battery voltage so it will begin generating. You will have to install one diode between the generator and the battery otherwise the battery will discharge through the generator when your bike is stationary. Good luck.
you pick a mechanical potential of spinning the motor, the path of the rotation would be certain the order of the levels interior the output. in case you turn the path of rotation, you will replace the order of levels. that's acceptable to 3 section autos. some autos can in simple terms be became around one course so pay interest or you will smash your brushes in a hurry. you will could desire to spin the motor on the precise speed this is indexed on the motor's faceplate or you wont see the 60Hz or the output voltage you assume. in case you will attempt to power electronics with this AC generator you pick extra aspects to normalize the frequency and voltage or you will in all threat blow issues out whilst your RPMs replace under a load / no load situation. you apart from could could desire to be sure the RPMs are consistently consistent or your output will selection notably.
