“Comparison of different Cooling system used for DC Motor” Case Study

The need of cooling arrangement for DC motor is very important to reduce the frame size of the motor. It required to select the effective cooling arrangement of the DC motor based on the application, surrounding of the motor installation and power consumption. DC motors are the workhouse variable speed drives in the continuous steel rolling mills for many years. DC motors in the steel rolling mills are usually separately ventilated. The quantity and quality of the cooling air can have major impact on the DC motor performance, operation, maintenance and life between overhauls. Energy consumption in the cooling system depend on which type of cooling used and what is the nature of load in that application. The air blower plays a vital role in optimizing the energy consumption. This article indicates that the how different type of cooling arrangement makes difference on the performance of DC motor, Maintenance and life of the DC motor and provide the information for selecting the better cooling system.
