For
applications when our B-Series Beetle motors aren't quite enough,
move up to the next larger version! These beefy motors are perfect
for many applications.
These
PK-Series motors are great for directly-driving wheels on small robots
(5-12 pounds), and are available with two different gear ratios.
Choose from either a high speed 27:1 or a high torque 51:1
