B Will a router motor have permanent magnets?

  1. Jun 1, 2017 #1
    Settle a bet:

    A reasonable sized (believe it is 2HP) router will not have any permanent magnets inside it upon tear-down. Instead, it uses an electromagnet.

    Correct?

    It's likely to be an induction motor (obvs no magnets) or an AC/DC motor with a field winding. (IMO)
