NPC-B81HT NPC-B81HT High Torque Left-Side Geared Motor <p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">This is basically the same motor as the standard B81 motor, but has more torque and a slightly different output shaft. These motors come standard with an electro-magnetic 24v parking
brake, which can easily be removed if that function is not necessary.
Built for continuous 24 volt 30 amp duty, they can be run at 36 volts
for 5 minutes, adding about 50% more speed and torque. This motor
comes in either left or right side shaft drive configurations, and
makes a great drivetrain for a large
robot. B81 is shown here. </font></p>
