    I bought this little devil out of curiosity – because the stated torque is big. I thought it was bigger in size (who reads the specs : -)))). When I received it (very fast shipping) and I realized how small it is, I decided to test it. I connected to its shaft a 3 x 3 mm flexible shaft coupler (Banggood Product ID: 993316) and from there, using a piece of rope, I hung a bag wherein I gradually added loads to find the motor’s torque limit. The coupler’s radius is R = 1 cm, so the torque in each case, as the motor was turning and the winding rope was lifting the load, was: Torque = R x load. I ended the test at a load of 1,5 Kg, which means that the torque was 1,5 – and the motor did the job. Fantastic. Note that the test setup is not fully proper, because as the load was hanging from the shaft coupler that was protruding (supported only to one end), apart from the torque to the axis of the motor, also a not at all negligible bending moment was applied to the axis and transferred to the reduction gear. In a proper laboratory test, the shaft coupler should be supported at both ends and this additional bending moment should not be present. The no load current is 0,04 A, the current under load gradually increases as the load increases and is higher than 0,07 A – but this is normal. Conclusion: Buy it. This is a really high torque. At this price, not to mention the size, I don’t think you’ll find something better. Thank you Banggood. 5 to 5.

    Отличный товар. Высокое качество, все из металла. В комплекте прислали еще 2 маленьких винтика.

    em excelente estado de conservação, tem um bom torque. só peca pelo tamanho. resta saber a resistência e durabilidade do sistema de desmultiplicação.

    For a desktop project, I just needed to turn a nut on a 6mm threaded shaft - and not too fast. Just the thing, and small enough to not get in the way.

    I like how the gears are made out of metal. Looks durable. Works great for spinning toys over the crib. I received this product in good condition and it works well. Im pleased with it. Thanks.
