It has apparently been used on only 5 questions. Two are for permanent-magnet motors and generators and one for a permanent-split-capacitor (PSC) motor.

I would be inclined to create and tags. A single tag might be better, but some people might not recognize it as meaning either a motor or a generator.

Would a tag be too unwieldy? I suppose that anyone who would be looking for that might be just as likely to look for . Perhaps the tag is all that is really needed, leaving the asker to give the sub-type as part of the description.

Usually, tags like this are created by people typing in words in the "tags" field and hoping for the best.

The low usage indicates that we do not need a tag for any of these, it would be better to use larger categories such as or . Just edit as needed to get rid of the tag, and then the tag will be automatically deleted when there are no tagged questions left.
