How can I build a hand crank generator to power a universal powermat?

AI Thread Summary
To build a hand crank generator that powers a universal powermat, the goal is to produce 10 watts at 120 volts, similar to the K-tor pocket socket. The project requires understanding generator assemblies and how to regulate AC output, with considerations for using either an AC or DC generator. A suggested approach involves using a Bodine motor as a generator, with a transformer to convert the output to the required voltage. The project emphasizes the need for hands-on experience in wiring and power production. Detailed instructions and guidance are essential for successful completion.

Alright, so I am building a hand crank generator, and my goal is to replicate the K-tor pocket socket. http://www.k-tor.com/

The goal is to power a universal powermat with the generator.

I need to produce 10watts at 120volts, and my group is completely lost. If anyone could provide detailed instructions it would be very welcomed.

It's a good thing that you have a few PF posts under your belt -- this thread almost got deleted as spam! :-p

Since this is a school project, you need to do the bulk of the work on it. What can you tell us about generator assemblies in this power range? How will you regulate the AC output? Do you think it would be best to use an AC or DC generator?
 
Here's the thing, I posted this because we have no idea. I know it needs to have an AC converter if I use a DC motor, and we thought we should feed the energy to a capacitor, but we don't have enough hands on experience to know how to wire or produce the power. Also, we don't know if it's necessary to use a 120volt DC motor
 
This is not a simple project, so here is something that worked. This project used an electric motor to drive a motor as a generator.
The motor was a Bodine model 5240. You will need this information to determine the speed to drive the motor/generator.
The motor/generator was a Bodine motor type 3302.
The maximum output was 17.3 watt 3 phase. You will only be using single phase so the maximum output will probably be only about 10 watt.
A transformer was used to convert from the motor/generator output to 120 volt.

Sounds like a fun project.
Good Luck

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
