Looks ok to me. Did you just acquire this motor or are you having any issues with it?

More than likely just a corroded/loose connection. It may look ok but it should be taken off and cleaned up,tightend down. If it's bad enough,replace the cable end or wire itself. Even a low/bad battery can cause things to heat up,as its trying to grab more amps than it can put out.
Also make sure the ground is good and clean.

The negative battery cable is usually bolted to the engine block.
