New 20D mm metal gearmotors

Our vast assortment of metal gearmotors has gotten even bigger! With over 100 micro metal gearmotor options and nearly 100 25D mm metal gearmotor versions to choose from, the next step seemed clear: expand our offering of 20D mm metal gearmotors, which fit nicely between the smaller micro metal gearmotors and larger 25D mm metal gearmotors. We have replaced our initial four 20D mm options with twelve entirely new gear ratios that feature more efficient gearboxes and much longer output shafts.

The motor portion is unchanged, and we now also offer versions with an extended motor shaft that rotates at the same speed as the input to the gearbox and can be used to add an encoder, such as our new magnetic encoder for 20D mm metal gearmotors, for closed-loop speed or position control.
