Abstract

The role of electric motors is important for human life such as industrial and home fields, namely 3-phase motors, AC and DC Motors then BLDC Motors. This study aims to determine the capacity of 2 BLDC motors with different sizes, namely 27 x 27 mm and 35 x 36 mm with RPM 1400 Kv as a mini water pump driver. The study was conducted for 14 days and calculated on average. Charging electric current from the solar panel to the 0,313 A battery with a charging time of 22,9 hours so that the battery is fully charged. Weather factors and the level of light intensity affect the acquisition of electric current from solar panels. The highest efficiency is obtained on a BLDC Motor with a size of 35 x 36 mm, which is 86,79% under load conditions and for 87.75% in no-load conditions and water discharge is 0,59688 L/s, the power consumption of the battery is 238,2195 Watts and the duration of the battery usage 7,585 minutes under load conditions. For a BLDC Motor measuring 27 x 27 mm, the efficiency is 81,69% under load conditions and for 86,51% in no-load conditions and the water discharge is 0,55992 L/s, the power consumption of the battery is 217,9702 Watts and the battery usage time is 9,324 minutes load condition. The decrease in the efficiency of the BLDC Motor is due to losses in the motor and friction losses in the pipe and the larger the motor size will be proportional to the required power value and the resulting water discharge.
