775 DC Motor DC 12V - 24V Max 12000 RPM Ball Bearing Large Torque High Power Low Noise Gear Motor Electronic Component Motor 2-Pack（with Bracket）

I got these for a long running project that's still in the "failed prototype" stages, so while I can't speak to the longevity of these motors for constant run time, I have connected both motors to 12 volt batteries and my lab bench power supply on numerous occasions, and at one point connected one in tandem to a PWM controller.During all these months of this kind of use the motors have taken it all in stride. Both run very quietly (for 775 motors anyway!) and smoothly. Once I get one or both installed in some DIY projects, I can predict with a high degree of confidence that both motors will last a very long time with proper use and care.

great product. just what i ordered

Working well no problem.

Fast shipping and great quality product.

I did the initial break-in for 20 minutes at 12v to get the brushes seated while monitoring motor temp by touch. Motors got a little warm but not too hot to touch. Installed them in my son's power wheels afterwards. Running at 18v one of the motors fan came loose from heat and the motor started smoking. Removed and replaced with the old 550 motors. This motor is supposed to be higher torque and accept higher voltage than the 550 motors i have, but they are not as described.

Had to place two orders for this item, advertised as a 2-pack. The initial order contained only one motor, while the second order included both.I utilized these motors to replace those in the Radio Flyer Go Kart. Although not exact replacements, they functioned after minor adjustments to the gear assembly and widening the motor seating hole. There are instructional YouTube videos available for further guidance. Additionally, the provided wire crimps were too small for the motor terminals.As of now, the motors have been successfully installed and appear to be functioning correctly. I have yet to test them under load conditions with the kids riding the go kart. Will provide updates if there are any issues with the motors.

I bought these to install an a 30 mm water jet drive for my RC robotic boat that normally requires a very high powered brushless motor I have use this at 12 V and it produces way more stress than I anticipated and that’s a 12 V at 24 V I’m getting double that for five times cheaper than what a brushless motor would’ve cost me

been using a cheaper 12 volt motor and fan blades to exhaust co2, not any more. these have ball bearings and a cooling fan. think they should last a long time.
