4QD recuperation with Thrige Titan motor

[zaprodk]

Hi.
I read in the last pharagraph that it is possible to use the Thrige Titan motor with the 4QD controller. Instead of me trying out different combinations, can anyone give me some advice on how to connect this? The information that the paragraph talks about is no longer available on the 4QD website. I tried digging around a bit on archive.org but didn't find the information.

My motor controller is the early model called 4QD-200 / 24-36-48V

Any help is appreciated.
Regards,
Per, Denmark.

Hi,

this is on the 4QD-Website:

Use with Series Wound Motors - 4QD - Electric Motor Control

Notes on using the 4QD series with series wound motors

www.4qd.co.uk

Simply connect the fixed Coil between Battery + and Battery + Input from the Controller. The rotating coil is connected as an 'normal' Motor.

IMPORTANT: Don't forget the Power-Diode parallel to the fixed Coil if you use Variant 1!

With Thringe-Titan motor, it could be helpful to keep the Compound-Coil connected while rekuperating. To do this, the combinated Pin of fixed Power-Coil and Compound-Coil must be the one connected to Battery +, the second Compound-Connection then can be connected to Battery - .

I will check this out by myself in the Future...

Werner, thank you for the kind help and link!
I didn't find the instructions myself because i was focused on looking for instructions on how to use a Compound motor and not a series wound motor.

The connection with powering the motor controller in series with the field is really weird and i'm not really sure how it makes any sense at all? (i'm drawing a schematic in my head and it looks weird to me to have the H-bridge "lifted" by the voltage drop of the field.
An alternative way would be connecting the field directly to the battery with a contactor, once the accelerator pedal is pushed - what is your thoughts on this?

It ist for You to Expiemental Things.....Work no limit ;-)
Think about to make this, to a real 4-Field Engine (Stator)
Soo like SEPEX !
More ETA
More NM
and more logical wiriring and Controller-Setup.

If i remember correctly, the current in the fixed coil must be reversed for rekuperation. So, while driving the current go from battery to controller. Changing to rekuperation, the current go back from controller to battery. This makes the trick and don't work with a direct wiring...

That makes perfect sense.
Thank you!
