Electric vehicles represent an effective alternative to reduce environmental pollution caused by emissions
from fossil fuel-powered vehicles. This study utilizes a 1500-watt Brushless Direct Current (BLDC) motor as the drive
motor. Unlike conventional DC motors, BLDC motors operate with three phases, requiring an automation system to
ensure optimal distribution of current and voltage across each phase. For motor control, a Convenient Speed Control
system with a maximum power of 3000 watts is implemented. This system allows the vehicle to move forward and
backward, as well as enabling manual throttle operation. During the experiment, the fully charged battery displayed an
initial voltage of 53.2 volts for the forward mode and 52.8 volts for the reverse mode. The current required for forward
movement was measured at 18 A, while for reverse it was 12.9 A. The minimum speed achieved by the electric vehicle
was 88.8 RPM, whereas the maximum recorded speed was 316.9 RPM. Thus, this control system is not only efficient in
regulating speed but also provides flexibility in operating the electric vehicle, supporting efforts toward more
environmentally friendly transportation solutions.
