Does an AC/DC motor care that much about the wave form?

They sure do. I've owned several so called "modified sine wave"
inverters in the past. Some tools refuse to start at all, others run
sluggishly with reduced power and increased heat.

Not related to motors, but we've had some appliances with digital
controls that refused to operate at all on MSW inverters..
