| Popis: | One of the radial generator problems is in its cogging torque production which leads to the decrease of output power. Cogging torque in radial generator is caused by air gap width variance between stator and rotor. This paper presents the method to reduce cogging torque in dual-stator radial flux permanent magnet generator (DS-RFPMG). It is a radial generator which has two stators located on the inner and outer side of the rotor. DS-RFPMG has a simple manufacturing, but its design is widely varied. This paper proposes stator tooth pairing and pole-arc ratio design to reduce the cogging torque in DS-RFMPG for low speed wind turbine, before they were combined. On stator tooth pairing design, the cogging torque was reduced. While on pole-arc ratio design, the cogging torque became larger. However, cogging torque was significantly reduced by 79.39% when both designs were combined. |
