RE: how to determine if DC mtr is PM
Substantial means that the voltage shall be close to nominal when running rated speed. And, say, 10 percent of nominal when running one tenth rated speed.
A motor with separate (or serial) excitation shows a lot less voltage.
It is, of course, also a good idea to look at the connections. If there are connections for an external field, it sure has one.
