WMYCONGCONG DC 12/24V 30W High Speed CW/CCW Permanent Magnet DC Motor (12V DC 3500RPM) and 37mm Dia Geared Motor Mounting Bracket Holder w/ 6mm Hex Coupling Random Color(Silver or Black)

Works Great!

I've been using this motor to drive a DIY rock tumbler. I am using a 24v variable power supply. It has been running steadily for almost 2 weeks at 3.3v and barely gets warm. With the timing pulleys and belts I used it turns the 4in diameter drum at a steady 60rpm. I am very pleased with this purchase.

Love the motor, nearly no noise and very fast. Coupler is not 6mm, the motor shaft is 8mm. Very frustrating that I had to reorder couplers

It’s very powerful and reliable motor. I have been using it even way beyond its specs (165 Watts) and it’s working smooth and holding. The coupler is useless and you have to buy separate one. In general it’s great product and value against price.

The motors work in reverse as well. I have two of these operating in sync to push items through a channel. Quite powerful for what they are, and very quiet. Im using them on a 24v system.

I don't know if i got a faulty part or something i tryed 12 to 24v 3 to 6 amps but the speed is not fast.

when you run it at 12V the motor is very weak and did not fit what I am trying to do with 12V only. Waste your money on something else that works only on 12V not 12/24V. If your application is a 24V then the motor actually runs smooth and has plenty of power. Gave it 3 stars because it would not run on 12V properly.

The media could not be loaded. I didn't know what to expected because of the mixed reviews, but this thing surpassed my expectations. This is really nice for the price. Attached a demo video of messing around with it.
