Rancang Bangun Generator Axial Flux Permanent Magnet (Afpm) Multicakram 1 Fasa Dengan Kutub Berlawanan (N-S) Menggunakan Magnet Permanen Neodymium Iron Boron (NdFeB)

Abstract

Axial Flux Generator Permanent Magnet (AFPM) is a generator that is producing relatively high voltages with low rotation. One of them is a multi-disc generator which has more stator and rotor discs than other types. The design of this single phase AC multi-disc generator using Neodyimium Iron Boron (NdFeB) magnets arranged with opposite poles on the opposite magnet. The first test is given a rotation of 3000 RPM on a generator with a total load of 8 parallel, each of which has 7 LEDs connected in series. The obtained generator output wave frequency is 400.6 Hz, load voltage is 14.65 V, load current is 13,704 mA, power is 0.2008 W, and torque is 6.39×10−4 Nm. The second test, the generator is connected to a full wave rectifier (full wave rectifier) which is then connected to the load, the rectifier output frequency is 800 Hz, the load voltage is 12,380 V, the load current is 13,340 mA, the power is 0.161 W, and the torque is 5.129×10−4 Nm. The third praise is to add a capacitor to the rectifier which functions to reduce the ripple voltage on the full wave rectifier, so that a DC voltage is connected to the load. Obtained a load voltage of 14,700 V, a load current of 15,147 mA, a power of 0.223 W, and a torque of 7.115 ×10−4 Nm. The greater the number of loads added, the smaller the voltage, while the current, power and torque are greater.
