Can I directly connect a DC alternator to a DC motor

So as my wind machine turns at different speeds the DC alternator it would power a DC motor driving a pump at different speed

Looking for 100 watt application.

Yes, BUT,
If you could arrange a Direct-Drive Mechanical Connection, it would be substantially more Efficient.
You are probably loosing ~50% or more of your available Power by changing Energy Formats Twice.
A Direct Bicycle Chain Drive is easily over ~95%+ in Power Transfer Efficiency.
A solid Drive-Shaft with Universal Joints is that high also .
