No, permanent magnet motors are DC motors that use direct current to have the other part of the motor interacting with the permanent magnet. So you have coils for the electromagnetic field. A motor has a stator and a rotor. On a permanent magnet motor, either the stator OR the rotor consists of a permanent magnet. The other part is a switchable coil-electromagnet.
There is no “free-energy” out of a permanent magnet to make a motor run on its own.
