1 Automatically turn generator on and switch power to it when they detect a drop in line voltage; turn generator off when they sense the line power is restored.  Can be used with portable generators as long as the generator has an electric starter.
Other types of generator use electromagnets to produce a magnetic field in a rotor winding. The direct current in the rotor field winding is fed through a slip-ring assembly or provided by a brushless exciter on the same shaft. permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil.
