A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
A telephone magneto is a hand-cranked electrical generator that uses permanent magnets to produce alternating current from a rotating armature. In early telegraphy , magnetos were used to power instruments, while in telephony they were used to generate electrical current to drive electromechanical ringers in telephone sets and activate signals ...
Demonstration hand-cranked magneto made circa 1925, on display at the Musée d'histoire des sciences de la Ville de Genève. 2kW Société de l'Alliance magneto generator for arc lamps, of around 1870. A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current.
The magnetic field of the dynamo or alternator can be provided by either wire windings called field coils or permanent magnets. Electrically-excited generators include an excitation system to produce the field flux. A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG).
A simple magneto (an electrical generator using permanent magnets) is able to produce relatively low voltage electricity, however it is unable to produce the high voltages required by a spark plug as used in most modern engines (aside from diesel engines). [2]
A generator coupling an EDFMG containing an 8.75 cm 3 of magnetic material with a spiral vector inversion generator yielded a pulse of amplitude over 40 kilovolts with a rise time of 6.2 nanoseconds. [4] Generators delivering pulses over 50 kV and 5 kA were demonstrated. [5] Ultra-compact generators with diameter less than 50 mm were developed.
