Sanjay, Simply by adding or removing pairs of gears. Instructions are supplied with the product.

Phill, Sorry but we are unable to advise on use of our motors with your controller without knowing its specification although the chances are yes as this motor only draws 300mA. You can find the motor rpm by checking out the motor which we also sell on its own or by multiplying the output rpm by the gearing ratio. i.e. 2,100x4 = 8,400rpm. The output speeds are quoted in the description for both 12 and at 24Vdc.

Can you tell me the diameter of the motor spindle and the gearbox output shaft? Thanks.

Phill, Please see the motor 1401-007 for full dimensional details. It is not listed here because it fits with the gears supplied. The output shaft is 3mm.

Hello. As i'm a bit of an imbecile about engineering, am i right to assume that the gears in the picture of the RE 280/1 gearbox kit are all on different spindles so the rotation can be transferred across to the orange one at the end which is fixed to the output shaft?

Phill, If you click on the image you can see a larger image size and you will see that all gears are on the two supplied shafts. You stack as many stages as you need to get your desired reduction ratio. Gears are either interference fit (grips the shaft) or clearance fit (rotates on the shaft).

Tom, We would not recommend stalling this gearbox as all gears are plastic and are an interference fit on the shafts.

Simon, We cannot guarantee technical support in the shop so you would be better posting your question here to avoid a wasted journey.

Brian, We get deliveries at least weekly so any back order for this product is rarely more than 3-8 days.
