From the photos, I'm pretty sure it has brushes and permanent stator magnets. I have no idea whether the rotor magnetic fields can be detected outside the motor, but I doubt it, with the steel casing and stator magnets shielding them. Maybe a hall effect sensor could be located inside the motor as close to the rotor as is practical; that might be able to count the passing rotor lobes, however many there are. That might be easier than dealing with the noise in the power circuit.
