Need some urgent help - Regarding some Circuit

I have a small circuit that is used to drive a motor of around 3000 rpm. I don't have the exact circuit but the PCB. It contasins a RX - 2 40319287 IC maybe for RF communication, a spiral antenna and then three leads to which a motor can be connected. The circuit runs on four 1.5V batteries. I got it from a toy car. There are actually three leads to which a motor is connected but i wanted to know if another motor could be connected to this so that it runs parallely whenever the circuit is powered up.

If I cannot connect a motor parallelly what changes should I make so that I can connect one more motor? Also, it seems that the circuit works on 6V(4x1.5V) but I want a higher power output so - Can i connect a 12V supply to this without burning up the components?

The motor that is connected has a capacitor( i wonder why) that reads 10uF 35V just for information. Please Help.

Hi

Technically it is not good to double the load of your circuit, you may burn it. another important issue is what you are activating with this motor you got, it is suitable for a toy car, but it may not be suitable for moving a heavy object. if you want to apply the ouputs to another motor you can apply a current amplifier which can be done by a follower emitter circuit. About doubling the voltage you need further analysis of your circuit, the characteristics of the IC and your motor.

Your help was invaluable to me. Thank you so much. I might not be able to get the specs of the components unless I have the proper equipment. But can you please advice me on how I can go about designing the common emitter configuration? And the IC that is being used is numbered RX-2 40219287 and I've searched everywhere for it but in vain. I'd be grateful to you if you could help me out a little more.
