DC motor on AUX

For my project I will like to control a brushed DC motor (high rpm motor used for cutting) in addition to the two BLDC axis.
I was thinking if it is possible to connected the third - DC motor - on AUX output instead of breaking resistor (I do not need breaking resistor for my application). Having PWM control on AUX output is enough since a can monitor the RPMs and adjust the loop by the host.
Has anyone tried to connect DC motor on AUX port?
