thanks for all, all things about my dc motor is now clear , the other two wires are for thermal protection , and in this motor you can't control speed of each wheel alone electrically, but there are hand break near each wheel which you can use to slow one wheel to steering the motor to other direction.

The 2 extra wires actually connect directly to the Turbo-Encabulator...

I have this question ?
Is't possible to run a series wound motor as separately excited or shunt excited motor ? by applying for example a dc voltage on field coil to be separatley excited , or it's designing to work for specific type ?
|
I do not think it would run. Something tells me that if it would run, you would not have much power.
Map out the coils, a certain type from different manufactures may be able to be modified differently.
Sorry for the vague answer.

return back after I run the motor on, by convert it from series to separately excited by applying about 1.5V to it's Rf and variable voltage at Ra and it's working well.
now I build a driver for a gate of MOSFET from 5V to 12V and generate PWM to this driver to control the speed of motor by changing the voltage at Ra. the mosfet driver will switching 110 Volt to Ra, when I applied 12V or 24V no problem but when I applied 110V to MOSFET(IRF640) It's damaged and it's the second one I don't know why since this mosfet is capable to handle 200V , 18A.
So I need to make 110V driver can handle this voltage and current , anyone can helo me ? I attached the schematic

Remove the zener diode (D3). It will limit the gate voltage to 9.1 volts not enough for the mosfet total conduction.
It is the case to use a flyback diode across the motor

All progress began with an idea
