Abstract

An alternator (10) has a housing (11), a pair of opposed magnet end plates (12, 13) mounted within the housing (11) a coil plate (14) mounted in and held in position within the housing (11), between the pair of magnet end plates (12, 13). A drive shaft (15) is located within housing (11) and is coupled to the pair of magnet end plates (12, 13). Each magnet end plate (12, 13) has a plurality of permanent magnets (17) disposed thereon. The coil plate (14) has a plurality of magnet wire coils (not shown) embedded therewithin such that they can be seen from both sides of the coil plate (14). In use, turning of the drive shaft (15) causes the magnet end plates (12, 13) to move relative to the coil plate (14) thus exciting each magnet wire coil (not shown) on each side resulting in the generation of an alternating current therein.

Description

technical field [0001] The present invention relates to an alternator, and more particularly to a permanent magnet alternator for converting mechanical energy into alternating current electrical energy. Background technique [0002] Current permanent magnet alternators typically include a rotor or drive shaft, a magnetic rotor assembly mounted for rotation on the rotor or drive shaft, and a stationary stator in which magnetic coils are disposed. When magnetic field flux moves relative to a stationary electrical conductor, such as a copper wire, or vice versa, the magnetic field flux will generate an electromotive force (EMF), or voltage, in the electrical conductor. If the conductor is connected to an electrical load, current will flow. The magnetic rotor assembly of current permanent magnet alternators rotates relative to a stationary stator and generates alternating current in the magnetic coils of the stationary stator. The magnetic coils of the stationary stator are co...
