Mathematical Modeling and Transfer Function Analysis of Single-Phase AC Motor Fujita ML 8012 for Control System Implementation

Abstract

Single-phase induction motors are essential components in both industrial and household applications due to their ability to convert electrical energy into mechanical energy. This study focuses on the characteristics and performance of the Fujita ML 8012 AC motor, aiming to determine its technical specifications and operational performance under standard conditions. Data collection methods include direct observation and systematic testing of components. The Fujita ML 8012 motor is rated at 0.75 kW (1 HP), with a nominal voltage of 220 V, current of 5.4 A, rotational speed of 1400 rpm, and a power factor of 0.72. Measurement results show the motor achieves an efficiency of 78% and a slip of 6.7%, which is within acceptable limits for single-phase induction motors. The torque generated is 4.9 Nm, indicating the motor operates effectively under medium load conditions. The study also notes that the operational temperature remains within a safe range, with a maximum of 75°C. In conclusion, the Fujita ML 8012 AC motor demonstrates reliable performance for general applications, particularly in light mechanical work and small-scale industries. This study can serve as a reference for selecting single-phase AC motors for electrical engineering purposes and as teaching material in energy conversion systems laboratories.
