Hello from Australia
« on: January 02, 2014, 06:25:24 AM »
I am a retired fitter and turner and like to build model steam/air engines.

 I have a lathe and mill/drill to make my engines.

 Nearly all of them run on compressed air, only one has run on steam from a friends boiler.

 Look forward to chatting to you all.

Welcome airmodel! Perhaps you could tell us what you'd like us to call you :)

We also love pictures, so don't hesitate to post photos of your completed engines!

Hi Airmodel, I'm also a qualified fitter and turner, but worked as a toolmaker all my working life. I live in Melbourne, whereabout's in Australia do you live?

Thank you for the welcome.

Paul I live in Victoria, about two hours drive from Melbourne.

I will have to post some photos and videos, just have to choose where to post them.

At the moment I am experimenting with brushless DC motors to use as small alternators for my model engines, has anyone tried this in this forum?

Bill.

Hello Bill, welcome to the forum.   :)

I've been looking at and thinking about brushless motors/alternators but so far have only used a conventional brushed motor. My thoughts were a bit deeper, wondering about the possibilities of using them as "dynostarters". The short time outputs seem quite high, but you would need some form of switching to use between the inverter/motor driver for starting and a diode bridge for generating.
Best regards

Roger

Once again thank you for the welcomes.

 Roger B I don't think they would be powerful enough to function as a starter motor unless it has been geared down. The one I am experimenting with puts out 35 watts. The AC output was connected directly to three light globes using a delta connection.

I posted a link in the engines section of a engine I made driving a brushless DC motor as a alternator.

Bill,

My thoughts were on a slightly different size range. The brushless motors used in the model cars and aeroplanes have quite high short term outputs, some hundreds of watts. They also are designed for high speeds, 10,000 rpm plus. I would have to do a few calculations, but one of these geared up 3 or 4 - 1 coupled to a 15 - 20cc engine would probably work as starter and generator.
Best regards

Roger

I had not thought of model aircraft and cars and if you have a high rpm engine those brushless DC motors will work well as a generator and starter motor
