DC Motor

I inherited the following DC motor:

Mamco 11/17/03
(illegible)-100-124 DI
100 VDC RR M

It's from a 120 vac portable winch. The DC motor looks
almost identical to a 90 v DC treadmill motor I have.
Unfortunately, it didn't come with the PSU. I've
emailed Mamco a while back to see what the voltage
range is, but they're apparently not going to reply.
Does anyone know if I can simply run this motor off of
a BR104 rectifier, or should I filter the output. I've
run it with just rectified ac under no-load, and can
control speed by using an upstream variac. Since the
motor appears to say 100 vdc, will I hurt it but
running it off of straight rectified, or even filtered
AC, without some sort of voltage regulator?

If I use it for an RSG, the duty cycle and load should
be so low that I'm not as concerned. However, I'd like
to build my PSU such that I could use it as a winch if
I decide to do so.

If it needs a filter, I'm afraid I'm out of my league.
I've Googled for filter design and circuits, but most
are way under 100 vdc.
