The main objective was design and development of an alternator to generate 4.5 kW power at 30000 rpm along with uncontrolled rectifier unit. The configuration chosen was to use permanent magnetic material for field excitation and the stator made up of silicon steel material. The objective was to evolve a methodology to design the alternator. Analytical calculation and the magnetic field analysis of the alternator were carried out. An air turbine drive was designed for testing the alternator. The demonstration of the alternator performance up to designed speed and power was carried out successfully
