The increasing of air gap length reduces the air-gap flux density. The analysis has been done for two different air gap lengths which were 2 mm and 4 mm using 2D FEMM 4.2 software at no load condition. The two dimensional finite element magnetic method has been deployed to model and simulated the characteristics of the machine which is based on the Maxwell equation. Effect of air gap length on the magnetic flux distribution, starting torque and MMF has been investigated. The effect of the air gap variation on the characteristic and performances of single rotor - single stator AFPMG has been described in this paper.
The axial flux permanent magnet generator (AFPMG) has been widely used especially for electricity generation. Kasim, Muhammad Irasari, Pudji Hikmawan, M. A drive coil selectively adds magnetic flux to and subtracts magnetic flux from magnetic flux flowing in the first and second magnetic flux path.Įffect of air gap variation on the performance of single stator single rotor axial flux permanent magnet generator A drive coil defines a third magnetic flux path passing through a third central portion of the actuator mechanism. Another permament magnet mechanism defines a second magnetic flux path which passes through a second end portion of the actuator mechanism. A permament magnet mechanism defines a first magnetic flux path which passes through a first end portion of the actuator mechanism. The linear magnetic motor/ generator includes an axially movable actuator mechanism.
[to generate electric energy using magnetic flux for spacecraft power supplyĪ linear magnetic motor/ generator is disclosed which uses magnetic flux to provide mechanical motion or electrical energy.
