Hi,
I am looking for any information and tips that you may have about the main drive motors that have been used on any model from any manufacture. I need voltage & current requirements and how the motor needs to be driven.
How do I identify one motor type from another?
How do I identify the leads?
If you know of any specialist chips that would help me to achieve that, please give me that info as well.
I know that some of the later machines are direct drive with I believe a VFD system, but there are still many around that use belt drive.
Some have clutches, some don't, but all seem to manage the washing cycle and reversing at relatively slow speed and also the high speed spinning......
I have started a blog on Yahoo to collect all and any information that you may have for me, with the eventual aim of making the information available to anyone who joins the blog to allow the use of a PICAXE Chip, running its own version of BASIC to control a complete washing machine.
That way, if a machine has a defective controller, you might be able to get the machine running again as a spare (most cannot wait till you have the controller up and running unless they live near to a Laundromat or similar!) for any future problems.
People who need two or more machines will be happy if they can pick one up from the junkyard and get it running as well as learning about PICs!!! A great hobby for some!!!
By the way, I already have a lot of information on how to interface solenoid valves and small motors like pumps, which only need to be turned on and off.
I am also recommending that Opto Isolation to be built in as well for obvious safety reasons. Nowadays that is not so difficult as it was years ago......that can be some form of optocoupler or even properly sized relays.....
I would also make the information freely available on CR4 as well.
If anyone wants more info about the PICAXE which is:-
a) very cheap due to the fact that the UK Government subsidizes them heavily
b) are quite fast running at up to 40MHz, so that even BASIC is more than fast enough for running a washing machine.
Go here for PICAXE infos:-

Some chips have PWM outputs, ADC inputs as well as conventional Digital I/O.
Some have the hardware for driving I2C and the ones that don't can have it implemented in BASIC, so the reading of I2C RTCs, temperature sensors or even expanded memory for larger data/software requirement is not a problem at all.
If you want to join Yahoo Blogs and follow my blog, search for PICAXE and my blog is called "PICAXE_DIY_CONTROLLERS".
I personally find that CR4 and Yahoo blogs complement each other completely, both are important to me.
Thanks for any help and assistance.
PS. The infos here should allow other projects to be easily achieved, a washing dryer for example or anything really!!! Other ideas gratefully accepted.
