Pulse motor build off time.

[MarkE]

Hi All,

Just a few more days to complete the 2014 pulse motor build off.

This is my update on my radial pulse engine test run.

It looks great.

Hi Mark,

I needed more computer power like arduino mega, ran out of pin ports to do more controls.

This is my basic specs.

Spec:
Radial Pulse Engine/motor/generator
Input 12v@3a max (motor input), stall load 56w
Input 9v@ 40ma (micro controllers)
8 coils 24 gauge at 100 ft each (2.567ohms)
PWM speed control
2 micro controllers for lcd and motor control (arduino base atmega 328 16mhz 32k)
ECM reading/controls
Rotational 5 degree steps (72 steps per complete rotation)
Control firing power stoke on each piston coil 0deg(TDC) to 180deg(BDC)
8 led piston firing lights
RPM reading (0- 3600)
Output:
BEMF collector from 8 coils

I hate it when  I come up short on pins.  One way around that if the timing isn't critical is to use an I2C I/O expander.  Otherwise just a chip with more I/O will do. 

I think your build shows a lot of creativity and you made it work the way you wanted, so my hat is off to you.  Good luck.

PMBO 2014 - Second Entry,
This is my second entry just in case the first one gets disqualified since i'm being lazy and running the DC motor with a PWM...lol...^^
At the 2.29 min mark it sound like i said "max of 200ma" but i said "max to 100ma" but since i talk funny it sounded like 200ma...lol
At the end of video are 3 pictures...;-)
Good luck everyone and remember to have fun...having fun and learning at the same time is of much more importance than to win...^^

Once again TJ,another nice build.
Hope you post it on IAEC

The machining is so good that until the end it is hard to see that it is rotating.
