DC 12V Electric Gear Motor High Torque Speed Reduction Motor 200 RPM with Centric Output Shaft 4mm Dia for RC Car Robot Model DIY Engine Toys

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.

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 size and power

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.

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 15rpm Can you help please Regards Kevin Ward

Great product

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

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

DC 12V Electric Gear Motor High Torque Speed Reduction Motor 15 / 30 / 100 / 200 RPM with Centric Output Shaft 4mm Dia for RC Car Robot Model DIY Engine Toys (200 RPM) Excellent little gearmotor. I got the 200 rpm unit and can set it as low as 10 rpm with a PWM speed control. Very quiet and good torque.

Good, steady motor for low RPM. The lowest I could get it was around 10RPM; the highest, around 200RPM.

habe ihn mit einem anderen motor verglichen, der angeblich vergleichbare Nm-angaben hatte, und dieser hier kam mir sehr viel schwächer vor. dann ging auf einmal auch noch einer von zwei motoren kaputt und ich bin kein anfänger
