The answer is no. Nor does it need to run inside a conduit. It would not be subject to physical abuse as long as it was kept between the joists. The standard NM cable of today has conductors with a THHN rating.

Does 220 wire need to be in conduit?

No, there’s no such restriction. If your circuit requires a neutral it must be run with the hot wires (conduit or in cable), similarly with the ground. However, if you don’t need the neutral, you don’t need to run it ( conduit or not).
