DC 12V Reduction Motor Electric Gear Motor High Speed Reduction Torque with 4mm Dia Center Output Shaft (100RPM)

Very high torque and sturdy construction. For mounting requires two short M2 bolts (most motors of this size use M3).

The gearbox is sealed, so a better choice over the smaller N20 or N30 type motors if you have space for it.Despite appearences, the gearbox is not planetary/epicyclic but is a multistage reduction using steel gears like the N20/N30 motors.The reduction ratio is fixed by type, so be careful which one you order. I have the "200RPM" which is the fastest in the range but unfortunately too slow for my application where it has to drive a worm gear that already gives some reduction. I will see if I can make it a 1:1 bevel gear drive which should then be about right.It runs smoothly although the motor whines a bit at the full 12v power.

The same motor as you'll find on may m any things, but the gearbox is good and strong, loads of torque. I haven't measured the 'weight' going through it at the moment, but it's more than I expected it to handle.

I initially bought just the one to try out in a Marble Machine I'm designing. The motor is very well made, it feels "weighty" and certainly is solidly made. The gearbox (looks like the body is a thick aluminium casting) has two screw attachment points, the drive shaft is sleeved in a 7mm bushing which looks to be made either of Brass or maybe Phosphor Bronze. Impressed! It will turn (at reduced rpm) down to about 6 volts and is happy running from a 9v PP3 battery. Altogether, a nicely made solid bit of kit. For the money (at time of review £7.08) it's a bargain, so much so I have just purchased another two for whatever future projects may come up! Highly recommended.

the size and power

Used to motorise a Ugears model windmill. Very effective with a 12 volt plug in adaptor.

This unit advertised as a High Torque variable speed motor, with four speed options. But seems to have been supplied as a fixed 200rpm speed motor with no instructions on how to adjust the speed (If possible) to my requirement of 15rpmCan you help pleaseRegardsKevin Ward

As expected

Good quality product

like small cylindrical size, using 30 rpm for scale wind turbines on my HO train layout, quiet, good product

Very tiny motor and images provided are with no scale reference for size, would not have brought it if i have known actuall size i was imaginings at least palm size this is finger size in real

Habe mehrer dieser Motoren für Modellbau gekauft. Sie erfüllen 100% ihren Zweck.

Buen par para su consumo. Se agradecerian versiones de 400 u 800 rpm
