6-12V Mini DC Motor, High Speed High Torque 390 Brushed Motor Replacement for Traxxas RC Cars, Power Wheels, PCB DIY Projects, Electric Drill, Toys and Hobby Models

Works on 9v great

I bought 2 of these about a year ago and threw them in my box in case I needed them later. This year I decided to make a Rock Tumbler, and I grabbed one of these. The biggest/only pain that I had was that the shaft size is 2mm where every pinion gear I could find on Amazon was 3.175mm so I had to hunt around a bit, found some eventually on a hobby site and put the gearbox together. This motor runs very quiet for the speed it runs at and has fantastic torque. I am running it well below spec because I want it to last - I am driving it with a 9V 2A supply, which gives plenty of torque to get the tumbler started when loaded and even at stall it will deliver much less than rated current (max power rated is 5A at 12V or 60W, I will stall at 18W which is less than 1/3 of that). From playing around with it I think running this at max power will overheat the motor and cause it to burn out, being designed for a drill it will handle 60W for short bursts only and you will have to watch the heat, but at 18W it runs like a dream all day. I can stall it without overheating and it has been running in the tumbler 24/7 now for 1 week with no problems.

I made a home made rock tumbler and this motor is running non stop at 10 volts no problem for days at a time

I burnt my fingers trying to stall the motor. It did not stall. The cheaper toy motors have metal on metal brushes so have limited life before the brushes wear out. The carbon brushes in this motor should last a good long time and you can replace them if they do wear out. It doesn't get hot in my application. It is built like a tank, a mini one. My major complaint is the noise but a quieter brushless motor is about 3 or 4 times the price. If the noise is not a problem, this motor is a great value for the price.

Arrived safely, as pictured, works!

Good

I bought 2 of these thinking I might be able to do some beginner DIY projects with these, but there is little information about these motors, such that doing anything with them isn't so straight forward. I did manage to get them running with an Arduino and L289N motor driver, controlling them with 2 10k potentiometers, but these motors are loud, need gearing (I'm not sure what would be compatible with these), and I'm not really sure what else to do with these other than test motor drivers are working. They don't seem to be very strong, but are super fast; perhaps they could be used in some kind on drill or flying RC vehicle, but I couldn't tell you where to look to find something that would fit onto the shaft of these. I had designed and 3D printed out a custom motor mount, a small pinion gear and differential gear based on the paltry info in the description, and it fits and works nicely, but again, not sure where to look for a commercial product solution for gearing specific to the dimensions of this dc motor.

Torque is good

Good motor for light level purposes, such as hobbies, crafts, etc. Very satisfied with this purchase.

パワーが有ります。よい製品です。

Delivery was on time. Item worked as it should. No issues

ラジコンボートのジェットスクリューの動力に購入しました。純正品は５分で焼損しましたので探していたら、本品が全くの同サイズで加工不要で取り付け出来て助かりました。12vで使用していますが問題なく動作しています。ただ、用途が違うので少々パワー不足が残念でした。本来の電動工具の交換パーツとして使用するにはコスパ的にお買い得だと思います。 このマークは無関係ですが消せないので済みません。→😭

トルクは満足でしたが、回転スピードが全然足りない。ラジコンカーでの使用ですが遅すぎました。
