i have removed the 1k resistor from postive to the collector on the first transistor and i have connected up a wire from the collector to ground .

the transistor turns off

 

That confirms that the power transistor is good.

If you have a 2.2K resistor, you can replace the 1K resistor in the collector of the first transistor with it. That will allow the transistor to saturate more readily.

i have placed a 2.2k resistor in the place of the 1k and

I GET A PULSE. it does not seem to be saturating fully but brilliant so far.
i am so happy after near a year YES
thank you very much a true hero

 

We still have some refinement left to make it so that you get a healthy pulse with both transistors saturating.

Lets try reducing the 10K resistor in the base to 4.7K if you have one. That will provide a bit more base drive for the first transistor so that is will turn on harder.

i have replaced the 10k with one of 4.7k, and it seem to be the same

 

Ok. That implies that the first transistor is getting more than enough base current. Lets try increasing collector load from 2.2k to 4.7k. The power transistor is a darlington transistor so it should be ok to make this change.

i have changed the 2.2k for a 4.7k resistor and i am getting a bigger pulse, but, still not fully saturating.

 

Let's ride this horse to the finish line. Take the collector load resistor to 10K and see what you get.

i have changed the 4.7k to a 10k but it seem to go the same speed. i think i have a three legged horse

 

Can you remeasure the voltages (with and without the magnet) on the collector of the first transistor to get our bearings again?

hgmjr

 

from the collector of the first transistor i get 0.02 volts without a magnet and 0.75 when i place the magnet over the magnet.
my trigger magnets are only 1mm squared and my pulse magnets are 12mm if that helps

 

The 10K collector resistor has obviously overdone. I guess we should drop back to 4.7K for the collector resistor on the first transistor.

Change it to 4.7K and then check the voltages on the collector of the first transistor again.

hgmjr

 

i have changed the 10k for the 4.7k and the collector with a magnet is 0.02 volts with a magnet over it it is 0.90 volts

 

Before the next adjustment, it might be a good idea to have a look at the output voltage swing of the HE sensor.

hgmjr

 

measure from the output of the sensor i get 11.24 volts with out a magnet and 0.20 volts on a magnet

 

when the disk is moving it drops from 11.24 volts to 8 to 11 volts

 

That is a very healthy signal out of the HE sensor.

What is your assessment of the performance of the overall circuit at the moment?

i am thinking . my coil is 26 gauge wire but i have a lot off turns on it about 1500 to 3000 turns. and it is an air coil which really does not help. i may have to make a smaller coil i will have to go back in to my room off tricks and make a new coil. if you do not mind waiting a few days i hope to build a new coil with a iron core this time.. i must thank you for all of your kind help, and i hope to show you my pulse motor works its true magic as soon as possible , thanks again

I will be around when you are ready to jump back into the effort.

Holy cow, that's a lot of wire!

If you want to save yourself some trouble, you could try salvaging a coil out of a 12vac relay or an 8vdc relay. The DC coils have a greater number of turns than the AC coils. Since in your application the spindle will be turning, thus switching the current on and off to the coil, so an AC coil would be more appropriate.

It already has an iron core, and the right amount of turns on it.
