Starter Motor

Hi Carroll
I was looking over starter motors and have another question for you if you don't mind...
How would I wire the motor into my system?
Is there a simpler way to wire this since I won't have an ignition wire?

Thanks

A starter question

Hi Carroll or anyone else who may be able to answer this

I have been reading up on starters so I can ask a more intellegent question about wiring starters...

If i wanted to use a wound field starter motor as a pulse motor would I have to continually send the pulse through the solenoid ?

Or once I get the motor started could I just pulse the current into the motor itself and bypass the solinoid once it is started?

Thanks again
Bizzy

You dont need the solenoid, just remove it. Problem with a starter motor is that most of them are poorly built with bushings and not bearings. Your motor, what ever you use will need to free wheel easily and smothly with as little friction as possible.

Hi Mark
I am not too mechanical ...how would i remove the solinoid?
Or could i leave it on and just pulse the motor directly?
Thanks

Hi Bizzy

The starter motor is just an idea of one type of motor that has a wound field. As Mark said they are not really designed for continuous running and the bushings they use for bearings are not as good as quality low friction ball bearings. If you can get some machine work done cheaply and have a source for some good bearings a starter motor can be used be redoing the end bells and doing away with the solenoid mechanism. A better choice would probably be a surplus motor that meets the size you need. Gotta go and take care of some things.

wound field DC motors

Hi Carroll
No problem I actually found some wound field motors for fans which I think will be perfect.
thanks again

Wound field Motor

Good morning
I am still working on my trigger coils for my flywheel and pulsed motor machine. I can start a thread to share my results and the direction I am going, just let me know if that is of interest to anyone...


In the meantime I have another question about motors. I understand that brushless motors are the same as permanent magnet motors.
However does that mean that would field motors are the same as brushed commutated motors???

I am asking becuase the would field motors I can find are either too big or too small for my purposes.

Thanks & let me know if the new thread would interest anyone.

... I do like the idea of pulsed flywheel personally, both in the frequency driven RV idea and the Jim Watson machine

I agree.There is a a thread on this:

thanks wrtner...I saw that a few weeks ago but forgot it was there. It seems like a more appropriate thread.

Hi Bizzy,

Yes a wound field motor is the same as a brushed commutated motor. What size motor are you looking for? Maybe I can help you look for one. I see you found the Watson thread. Good luck on your build.

Hi Caroll
I am not sure I am kind of deciding by the seat of my pants what size motor i need. Plus cost is a big factor.
the motor I have is a 12 volt 3.3 amp motor see Electricty's Watson machine link. I have the trigger design posted there. You were a great help there...
I am loosing to much rpm when I turn the motor on, so i know i am also loosing voltage and current. I know I need something with more torque. But your answer has just opened up a whole new possabilities of motors from Allied electronics. I will keep you posted
(should i keep posting updats on Electricity's watson thread, this thread or a new thread...I want to make it easy for folks to see my work in case they want to use my design and ideas)
Thanks

Hi Bizzy,

I think I would use the Watson thread. What you are doing is probably closer to the Watson machine than the Campbell idea.

Hi Caroll
I agree it is much closer to Watson's design...thanks again for all of your help.
