You shouldn't need that.  A motor can be its own filter.  You can chop the
motor from substantially higher voltage than what it is intended to run at,
just make really really sure the duty cycle is low enough so that the
average is right.  Put another way, you need a buck converter, but the coil=
s
in the motor can be the inductor and the final load at the same time.
