Analysis of Heat Calculation on DC Motor Strengthening Shunt due to Continuous Work (Continuous Duty) Starting at the Time of Start until Braking (Application in the Laboratory of FT-USU Electric Energy Conversion)

Introduction

The DC motor, a device that converts electrical energy into mechanical energy, has become a crucial component in various industries. The DC motor strengthening shunt, with a parallel magnetic field setting with an anchor coil, is widely applied in systems ranging from water pumps to cranes. However, the continuous work of DC motors (continuous duty) raises its own challenges, namely the emergence of heat due to energy losses. This heat, if not controlled, can damage the isolation of the motor and cause system failure.

In this study, we will examine more deeply about the heat calculation of the DC motorbike strengthening shunt for one work cycle, starting from the start process, to reaching the steady state, and finally stops (braking). This study takes the example of applications in the Laboratory of Electric Energy Conversion, Faculty of Engineering, University of North Sumatra (FT-USU) as a forum for research and learning.

Hot Journey in a Work Cycle

The hot journey on DC motorbike strengthening shunt for one work cycle can be described as follows:

Start Phase

When the motor is turned on, a large start current flows through the anchor coil. This current produces significant heat due to coil resistance. This heat will propagate to other parts of the motor, such as iron core and frame.

Steady State Phase

When the motor reaches a constant speed, the anchor current decreases and the resulting heat is also reduced. However, the energy conversion process still produces residual heat released into the surrounding environment.

Braking Phase

During the braking process, the anchor currents increase again, causing an increase in heat. This heat can be overcome by using the right braking system, such as electromagnetic brakes or dynamic brakes.

Hot Loss Analysis

The heat losses on the DC motor strengthening of the shunt consist of several main components:

Copper Losses

These losses occur due to resistance of anchor coils and terrain coils. The current flowing through this coil produces heat that is proportional to the square of current and resistance.

Iron Core Losses

These losses are caused by the current Eddy and hysteresis that occurs in the motor core of the motor. Eddy currents arise due to rapid changes in magnetic flux, while hysteresis is caused by the magnetization and demagnetization properties of iron core material.

Mechanical Losses

These losses include friction on the bearings and wind friction that occurs due to motor rotation.

Additional Losses

These losses include the heat generated by the brush and commutator, as well as loss of power due to radiation and convection.

Importance of Heat Calculation

Accurate heat calculations are very important to ensure optimal and safe motor performance. By understanding the distribution of heat during a work cycle, we can:

Designing an Effective Cooling System

Choosing the right type of cooler, such as a fan or air cooler, to eliminate excess heat and keep the motor temperature below the safe limit.

Choosing the Appropriate Isolation Material

Choosing an insulation material with the ability to withstand the temperature produced by the motor.

Preventing Motor Damage

By understanding the distribution of heat, we can take preventive steps to avoid damage caused by excessive heat.
