2 Pcs Universal 550 30000 RPM Electric Motor with 10 Teeth Gear , RS550 12V Motor Drive Engine Accessory for Kids RC Car Children Ride on Toys Replacement Parts

These are pretty good motors, but they are not 30,000 RPM as advertised. I used a professional optical tachometer and tested the RPM at 12.0 volts, no load (i.e., nothing attached to the motor shaft.) After testing each motor several times, and averaging the measured RPMs, I came up with 24,824 RPM. These motors are probably capable of providing 30,000 RPM but at a voltage higher than 12 volts. For my application they work well regardless of the inflated RPM @12v spec.

according to the part number search that I did this is not even close to being the right part number.

These are good quality. iMy motors were 10,000 rpm stock I replaced for my sons jeep ride on toy with remote. The motors fit perfectly they came with the pinion gears already attached. On the can of the motor it says 30,000 rpm pretty sure it says 60 watts and the stock ones were like 40 watts. The esc control box needed cooling in order to use these motors or the plastic will melt and like description says, "easy to burn'. I attached a cooling fan to the housing and it works great. These will make your car extremely fast if switching from 10k motors I also upgraded my battery keeping it 12 volts. I would say the new top speed over 10mph with plenty of power and motors stay relatively cool they have nylon fan blades inside. I recommend this upgrade just keep in mind you may need extra cooling.

Installed the motors on my son's 12 volt ride on atv. I had to swap the gears but they were a direct fit. They lasted about 5 rides then the left rear motor went out...... if anyone knows a decent replacement motor please let me know cause these are not...

Both motors burnt out within 5 minutes of use

Burnt out in less than five minutes
