I have a power wheels jeep, it has 2-12 volt 550 motors, 1 for each side. I need 1 motor and set of gears that can produce the same, or a little more, torque and rotation as the 2 combined produce. I know nothing about electric motors but am trying to learn more. I have built something and will be mass producing it and need this motor and gears for the prototype. I built one with the power wheels drive train but I need to make it more compact. PLEASE HELP.
Can you see if the motor you have has specs written on the case, and an idea of the torque?
If you don’t have any information, then you might take a look at the drive motor sizing tool:

Once you have a torque, RPM and nominal voltage, you can likely find a solution here:

These are the numbers on the motors, not on a plate just stamped in ink…00968-9003…63822…3D2022
Unfortunately the numbers don’t really reveal anything. The important factors aside from nominal voltage are current, RPM and torque.
We likely won’t have a drop-in replacement, so if you’re looking for something custom, try the drive motor sizing tool.
Thank you for your help, I did more research and some conversions, do I have this correct…1/4 horsepower = 0.186425 kilowatts = 15.5341 amps. If this is correct, does that mean it takes about 15.5 amps to create a 1/4 horsepower? I need a motor with the following requirements,… 12 vdc brush motor, 50 rpm min - max 1000 rpm, max 30 amp at max rpm, 1/8 horsepower. If it is a small motor I will need some gears, it needs to spin a sprocket at least 50 rpm. I want to connect the 48t sprocket, product number RB-Sct-232, as long as I can get this sprocket to spin at 50 rpm or higher, that is all I need.
You cannot equate Watts to Amps; Power (Watts) = Voltage (Volts) x Current (Amps).
Therefore if you have a 12V motor, and want 1 Hp, the motor will likely draw around 15.5A. Keep in mind though that often the “power” figure provided is the maximum, which might stall the motor and cause it to fail. Be sure to read the specs.
