Abstract

The main issue of using a permanent magnet in electric machines is the presence of cogging torque. Several methods have been introduced to eliminate it, one of which is by employing a coreless stator. In this paper, the load characteristic analysis of the double-side internal coreless stator axial flux permanent magnet generator with the specification of 1 kW, 220 V, 50 Hz, 300 rpm and 1 phase is discussed. The purpose is to learn the effect of the load to the generator performance, particularly the output power, efficiency and voltage regulation. The design and analysis are conducted analytically and numerically with two types of simulated loads, pure resistive and resistive-inductive in series. Each type of load provides power factor 1 and 0.85 respectively. The simulation results show that when loaded with resistive load, the generator gives a better performance at the output power (1,241 W) and efficiency (91 %), whereas a better voltage regulator (5.86 %) is achieved when it is loaded with impedance. Since the difference in the value of each parameter being compared is relatively small, it can be concluded that the generator represents good performance in both loads.

Abstract

Vibration in a generator is an important factor in detail of design. To know the behavior of the vibration, a test is performed using vibratiometer. The aim in writing this paper is to obtain reference classification of vibration that can be viewed on a standard IEC 34-14 and DIN EN 60034-14. In this paper the results of testing, the value of velocity and acceleration, will be measured analytically so asto create value that can be used to compare the value of the test results with the value from 34-14 IEC and DIN EN 60034-14 standards.

Abstract

This paper discusses magnetic simulation and analysis of radial flux permanent magnet generator (PMG) using finite element method (FEM) by utilizing open source software FEMM 4.2. The specification of generator is 25 V, 28 A, 3 phase, 300 rpm. The analyzed magnetic flux was in the air gap, stator teeth and slots to find out the distribusian pattern and its fluctuation. The simulations were conducted in no-load and nominal load (28 A) conditions. Furthermore the maximum flux density of simulation (Bg(sim)) was used to calculate phase voltage Eph to find out the magnitude of generated electromotive force (EMF). The calculation results were presented as voltage vs. rotation graph in no-load condition and voltage vs. current graph in nominal load condition. Both graphs were validated with Eph of experiment result (Eph(exp)) and Eph that the value of Bg obtained from analytical calculation (Eph(calc)). The final results showed that in no-load condition, Eph graph with Bg(sim) (Eph(sim)) was close to Eph(exp) and Eph(calc). The error rate with respect to the experiment was 6,9%. In nominal load condition, Eph(sim) graph almost coincides with Eph(calc.) graph, with the voltage drop of both was 0,441 V. Both graphs however were far different from Eph(exp) graph, which has 9 V of voltage drop. The overall results demonstrated that magnetic distribution pattern presented by FEM was very helpful to avoid magnetic flux accumulation in a particular segment. Besides Bg(sim) facilitated to predict the value of Eph.
