Introduction

Direct current motor or DC motor is a device that converts electrical energy into mechanical energy. The use of this motorbike must be adjusted to the need to operate economically and efficiently. To achieve optimal performance, direct current motor must have high efficiency and torque. One way to improve DC motor performance is to adjust the position of the brush and add the auxiliary pole. In this article, we will discuss the effect of brush position and addition of auxiliary pole on efficiency and torque of DC Shunt motor.

Understanding DC Shunt Motor

A DC Shunt motor is a type of DC motor that uses a separate field winding and a separate armature winding. The field winding is connected in parallel with the armature winding, and the current flowing through the field winding is independent of the current flowing through the armature winding. This type of motor is commonly used in applications where high torque and low speed are required.

Importance of Brush Position and Auxiliary Pole

The position of the brush and the addition of auxiliary pole can have a significant impact on the performance of DC motorcycles. With the right brush position, the electric current can be flowed optimally to the coil, thereby increasing the efficiency and torque of the motor. The addition of auxiliary poles also plays an important role in increasing the magnetic power produced, which in turn can improve the torque produced by the motor.

Experimental Setup and Results

In a study conducted in the FT-USU electrical energy conversion laboratory, the test results showed that the highest efficiency of the DC Shunt motor without a helping polar occurred at the brush position of +30 ° with an efficiency value of 64.70%. Meanwhile, the efficiency of the DC Shunt motor with a slightly better help polar, which is 65.09%. This shows that the addition of auxiliary poles can make a positive contribution to motor efficiency.

In addition to efficiency, torque is also an important parameter in the appraisal of motor performance. In this study, the highest torque was obtained at a brush position of -30 ° for DC Shunt motor without auxiliary polar, which reached 2.88 N -M. Meanwhile, the DC Shunt motor with a helpful polar produces a much higher torque, which is 13.23 N-M. This significant difference shows that the addition of auxiliary poles not only increases efficiency but also motor torque, so that the motor can operate better in various load conditions.

Discussion and Conclusion

Seeing this result, it can be concluded that the setting of the position of the brush and addition of auxiliary polar has a great influence on the efficiency and torque of the DC Shunt motor. This study provides important insights for the development of DC motor technology going forward, especially in applications that require high performance and maximum efficiency. With this understanding, engineers and researchers can design a better DC motorbike to meet the increasing demands of industrial applications.

Future Research Directions
