I have some small dc motors with very high quality (expensive ) Hubner tachos on the back end.The tachos are the GT-3 type which don`t have bearings but mount on an extension of the motor shaft.
I want to use these tachos,and the easy way to mount them on my new application is to keep the motor/tacho as one piece and mount the whole lot on the back of the motor I am using.
To put the size into perspective the motors are about 1.5" dia x 4" long which is infinitely smaller than the tachos usually used.
Question is,what do I do with the output the redundant motor is going to generate or how do I stop it generating/burning out.
Would removing the brushes be enough?
the motors are 48v 70W Maxons.
+1 on removing the brushes.
I do the same in the opposite fashion when no longer using a tach on a modern drive using torque control mode instead of velocity, often the tachs are built in so the only option is to remove the brushes to avoid possible carbon wear down to the springs and dust.
