Motor

Hello, I am new here and I want to buy an electric motor but I want to give power but no speed to the car, what do you suggest?

Can you explain a bit more about the use of the motor, what you say “give power but not speed”? The more information you can provide the better.

I want to carry load without pushing the motor. I don’t mind about the speed.

Would a servo motor fit your needs?
