Oct 13, 2025 by wbrum.org 97 views

Introduction

Electric motors are the backbone of modern industry, and the three-phase induction motor is the most widely used type due to its ease of maintenance and high efficiency. Approximately 70% of the energy generated by power plants is utilized by these motors. In the industrial world, motor speed regulation is crucial to increase efficiency and precision in the production process. The advancement of power electronics has presented a practical solution: Inverter Variable Speed Drive (VSD). This technology allows for easy motor speed setting by changing the voltage frequency supplied to the motor.

The Role of VSD in Motor Performance

The Electric Motor Laboratory Center for the Development and Empowerment of Educators and Education Personnel has conducted research to explore the effect of VSD on the performance of the Tiga Phase Induction Motor. The study aimed to reveal the impact of VSD on motor performance, including its influence on motor loss, noise, and efficiency.

Experimental Methodology

The test was conducted by varying the supply frequency (50 Hz, 30 Hz, 35 Hz, 40 Hz, 45 Hz, 50 Hz) and motor load (0.5 Nm, 1 Nm, 1.5 Nm, 2 Nm, 2.5 Nm, 3 Nm). The results showed some interesting facts:

Increased Motor Loss

The use of VSD resulted in increased losses in the motor. This is caused by an increase in current and voltage that occurs when VSD changes the frequency of supply. The increased losses can lead to reduced motor efficiency and increased energy consumption.

Increased Noise

Motorcycles run by VSD tend to produce more noisy sounds. The cause is an increase in mechanical vibrations due to changes in the frequency of supply. This can lead to a negative impact on the work environment and may require additional noise-reducing measures.

Better Efficiency with Direct Supply

At the same frequency (50 Hz), the motor that is supplied directly from the nets indicates better efficiency compared to the motor run by VSD. This suggests that direct supply may be a more efficient option in certain situations.

Exploring Research Implications

The results of this study provide a clear picture of the effect of VSD on the performance of induction motors. Although VSD provides flexibility in speed settings, there are trade-offs that need to be considered. Increased loss and noise can reduce motor efficiency and cause negative impacts on the work environment.

The Importance of Determining the Right Use

Before implementing VSD, consider important factors such as speed regulation needs, permitted noise levels, and motor efficiency. In some cases, the use of VSD may not be optimal, especially if the main priority is efficiency and lack of noise.

Towards the Optimal Application of VSD

Knowledge of the influence of VSD on motor performance is very important in choosing and implementing this technology. Research in this electric motor laboratory is an important step in understanding trade-offs and optimizing the use of VSD. With the right information, the industry can effectively use VSD to improve the efficiency of the production process, but still maintain the smooth operation and work environment that is safe and comfortable.

Conclusion

The use of VSD inverter on the Tiga Phase Induction Motor has both positive and negative effects on motor performance. While VSD provides flexibility in speed settings, it also increases motor loss and noise. The results of this study highlight the importance of determining the right use of VSD and considering factors such as speed regulation needs, permitted noise levels, and motor efficiency. By understanding the trade-offs involved, the industry can effectively use VSD to improve the efficiency of the production process while maintaining a safe and comfortable work environment.
