For
years, there has been a void in the realm of conveniently-priced
gearmotors for the 12-15 pound robot weight class. Look no further!
The HG-series gearmotors are beefy enough for the most demanding
15 pound robots, and possibly even more- yet they won't break your
budget! Perfct for directly-attaching your wheels right to the ouput
shaft. Available in two different gear ratios, so you can choose
either a higher speed 20:1 or a higher torque 62:1 option.
The
gearbox has four face-mount threaded holes. Gearbox is offset-shaft,
spur gear type, and is sealed, maintenance-free.
These
motors are meant to be run at 12V, but we've tested them to run fine
up to 24V.
