Motors for Rover

I have an RC car with 3 motors, two in the back and one in the front. The two in the back are controlling the throttle/speed of the vehicle, the dc motor in the front seems to be steering, since when I unplug this wire the vehicle, the vehicle only moves forward and backwards .

I have an ESC that I was gonna use for the back 2 motors , but for that front motor , I am confused on how to connect this because it only has 2 wires instead of 3 .

Can someone help or give advise on a possible solution ?

Thanks community

Probably a brushed DC motor.

how would connect this to Pixhawk, would I need another ESC? or do I need to take another approach

If it’s a brushed motor you need a brushed motor ESC. It’s not a servo?

I thought it was a servo at first until i was ready to connected it to the pixhawk and I noticed that it only had 2 wires i know usually servos have 3 wires so now I believe its a dc motor

Right, you said 2 wires sorry. It’s just odd to have a motor for steering. But anyway if it’s a brushed motor you need a brushed motor ESC. Got a photo of this steering motor?

Does the car have proportional steering? Or does the steering always go all the way?

Yea, looks like a brushed motor. To Sebastian’s question is this just Bang-Bang control? Center to full left or center to full right?

The steering goes all the way

The steering goes all the way left or right

Another question that y’all may can help, I have a ESC that can be used on two motors , if I wanted to use skid steering instead with my two rear , I would need to 2 output pins to connect to the pixhawk correct ?

Hello, I’m developing a rover, do you have any suggestions for connecting a 2-wire acceleration engine

This tells us nothing about the application other than it’s a brushed motor (2-wire)
