/members-area/personalblogs/b/blog/posts/getting-better-with-dc-motorsIn the recent Month of Robots competition I made something I called SuperRobot, but disapprovingly it wasn&#39;t so super as the DC motors and drivers I selected just didn&#39;t seem up to the task of moving the quite heavy chassis. I decided that I ...en-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/blog/posts/getting-better-with-dc-motorsWed, 05 Jun 2019 11:28:56 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:87933951-30aa-43f1-9b39-1952c86866dabalearicdynamics0<p>Nice Dubbie!</p><p>&nbsp;</p><p>Note that there is also a thin shaft to the back of the motor (the part opposite to the reduction gearbox). It is a very interesting solution I think; this shaft rotates at the real RPM speed of the motor, no matter the reduction applied to the other side, and can be used to connect a rotary encoder for any kind of feedback. Using these motors with the Infineon Arduino DC motor controller shield, as well as with the micro:bit Kitronik&#39;s All-in-one robotics board, the speed is very stable when controlled with PWM frequency.</p><p>&nbsp;</p><p>Enrico</p><img src="https://community.element14.com/aggbug?PostID=7232&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">
