0-PD51M PD51M Planetary Metal Geared Motor 51:1 <p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">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 PD-series gearmotors are beefy enough for the most demanding 15 pound robots, and possibly even more- yet they won't break your budget! Perfect for directly-attaching your wheels right to the ouput shaft. Available in three different gear ratios, so you can choose between a <a href="0-PD27M.html">higher speed 27:1</a>, a <a href="0-PD51M.html">higher torque 51:1</a>, or a <a href="0-PD264M.html">maximum torque 264:1</a> option.

<p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">The gearbox has four face-mount M3 threaded holes. Gearbox is all metal gears, and is sealed, making it maintenance-free.</font></p>
