Savonius windmill having advantages high starting torque and simple construction is applicable for Indonesia as a developing country with annual average wind speed 4,5 5,0 m/s. The purpose of the experiment is to identify characteristics of an electric machine used for low speed electric generator. The electric machine for the experiment is a permanent magnet electric motor usually used for electric bicycle. The electric motor is tested as an electric generator and rotated with variations of speed. Outputs of the generator are torque, voltage and current with 1) variation of lamps-load, 2) constant voltage-load for 12 volt and 24 volt battery charging and 3) combination of 12 volt battery charging and variation of lamps-load. The average efficiency of the generator is 59,8% and 65,4% for 12 volt and 24 volt battery charging. Battery charging starts at 95 rpm and maximum electric generating current is 20 Ampere at generator speed about 175 rpm.
