How does it become an electromagnet? An electromagnet consists of a length of conductive wire wrapped around a piece of magnetic metal. The voltage regulator is an electronic device that acts like an alternator voltage monitoras it keeps an eye on the battery voltage. Isolated Negative, the alternator frame/mounts aren't 'Grounded', so reverse polarity is easy, 4. If youre a Ford guy or a Mopar gal, thats fine just make sure your alternator has a built-in voltage regulator. The induced voltages will be AC because of the electromagnetic pole changing during the rotor rotation. Electricity for my off-grid cabin comes from solar and wind power stored in a bank of four 6-volt golf cart batteries wired for a 12-volt system. Our Ford Focus alternator Searching for car alternator conversions reveals a variety of pages, HOWTOs, and guides, many of which can be extremely confusing and overcomplex. If you want an induction motor to self-excite as a generator you need to connect a sufficient capacitor across one or more of the windings then drive the motor at or above synchronous speed and it will self-excite and be ready to deliver power to loads. (In fact, without the two resistors, striking an arc would nearly kill the 3-HP Briggs & Stratton engine!). Yes a 3-phase Motor could work as a 3-phase Generator if it is rotated by some external source, its frequency dependent on its shaft rotation speed and number of poles. JavaScript is disabled.
