Controller circuit for Hilden Brandt motor needed..

[Elisha]

@Steve, Jack

There are many wise to make experiments with the motor, but we do not have all the mechanical or electronic abilities to do it.
We can get organized to make the development of this fast motor but, many could to contribute.

What do you think if we can make a kit for the people of this group, for all make testing?

The Kit will have a fully assembled motor and a controller.  The one that is in charge to assemble kit paid to him by its time.

the first thing is get a list of sponsors, each sponsor will have a kit, and make experiments.

Who want to be in the list?

Hi, Elisha.
Personally I doubt that a third party could make a controller without having the motor at hand to test and measure. Good controllers are not all that simple, and especially when there are strange behaviors going on in the motor. And besides that, we are not even at the point that 'everything' is fully understood what happens in the motor. So little real tests have been done, and next to no test data is available.

Regards,
Steven

Hi Friends.  Jack, Steve, Carl, Wattup, etc

I contact to Randall from Electronic Light, Trying to make a budget to the controller for Jack,  This will accelerate the development of Jack Motor, This are good news.   With a budget we can make a donation plan to pay the controller

This is the response, What you Think that I need to replay? 


>>Hello,
>>I will need more information about the motor. Is there a website for the motor manufacturer with a specification?

Hi

We need a budget for a controller for a  permanent magnet DC motor, This motor have 3 valves , each valve work with  150V DC,  0,8 Amper continuos current, 2 Amper peak.

The voltage is trigger on off from an opto coupler in the motor, for 500 to 3000 revolution per minute.    The output of the controller need to have protection of the motor voltage running generation of 350V added to the 150 VDC of the input and BEMF short voltage peak of  -1500V.

The running dynamics of the motor are: when 150 VDC is applied to the  input, the motor star to turn, then the voltage start to going up to 450V, the voltage increase come from the motor inside not from the power source.

We want to control the off time before the off time indicated by the opto coupler.

Please make a budget to make the controller for us.
Thanks.

Hello Elisha,
I appreciate your input, but I doubt that anyone would pay that kind of money for an experimental device.
To give you an idea what It would cost if I were to build my model and charge man hours:
Materials: cores, magnets, aluminum, bearings, steel = 90euro (no shipping cost counted which were 50euro for the cores alone)
Circuit: parts= 10euro
Machining and making the motor, including the circuit = at least 600 euro.
So that is a total of 700euro

Ragarding attraction force in this rotary design,


Does the attraction force versus electric input increases with closer and closer alignment of rotor and stator cores?
force beeing strongest when rotor is in fully aligned  with stator  ?

thanx

Yes an airgap can be though of as a resistor, so a 0.01 mm airgap is way better then 0.1mm
The valve will switch with less effort.
