Applications of DC Electric Motors As A Drive for Grain Threshing Machines
Abstract, The application of a DC electric motor as a driving force for this grain
thresher machine uses electrical energy from a solar panel which is then stored
into a 24 Volt 50 Ah accumulator. The observations on the driving motor carried
out were data collection related to the value of the voltage and current generated
by the motor, motor speed, input and output power, torque generated by the DC
motor, and the length of time the motor worked without solar panels if no solar
energy was obtained. The results of testing and calculations when the engine is
run without load with a 24Volt 50Ah battery obtained an output power of 176.24
Watt, a current of 9.15 Ampere, a motor rotational speed of 3070 RPM, and a
thresher cylinder pulley speed of 745 RPM. In testing the machine using a grain
load of three repetitions, the average output power of 223.55 Watts, a current of
11.73 Ampere, a motor rotational speed of 2900 RPM, and a thresher cylinder
pulley speed of 703 RPM, this value is influenced by the friction force of the
grain. rice against the threshing cylinder. The estimated ability of the battery to
run the grain threshing machine with the average current generated by the DC
motor during load testing with grain is 3.41 hours without solar panels.
