In the market, there are various types of electric motors available nowadays. Among them one can perform specific work better than other, so selecting the right type of motor for required purpose is not so easy.
Factors affecting the Selection of an Electric Motor
There are various factors that must be considered for selecting right type of electric motor for required purpose. The factors affecting the selection of an electric motor has been listed below.
- Nature of Supply available for the motor
- Nature of Load to be connected to the motor
- Nature of Drive of the motor
- Torque generated by the motor
- Speed of the motor
- Size and Rating of the motor
- Cost of the motor
- Efficiency of the motor
- Environmental conditions in which the motor operates
Nature of Supply available for the motor
There are two types of power ( A.C or D.C power), so before selecting a motor must consider which type of power source available to supply to the motor. Also consider about either single phase or three phase ac power in case of ac power available.
Nature of Load to be connected to the motor
When selecting an electric motor you must consider have to consider either the load require heavy or light starting torque, either the torque increases or decreases with the speed or remain constant.
Nature of the Drive
There are various types of drive available, each type of drive has its own unique feature and benefit. The drive must be compatible with the motor and must consider motor has to drive either single machine or group of the drive.
Speed of the Motor
Output speed of the motor must compatible with the needed speed.
Torque generated by the Motor
Suitable torque is necessary for an electric motor startup and acceleration for needed speed, so must choose an electric motor so that generate sufficient torque and operate without having excessive strain.
Size and Rating of the Motor
When selecting an electric motor, you must consider the physical space available for the motor as well as base is strong enough for motor's weight.
Cost of the Motor
Both capital and running cost of the motor must be considered before selecting a motor, it must fit on your budget. Also consider any repairing or maintenance cost.
Efficiency of the motor
Always choose the motor with high efficiency. A highly efficient motor saves energy and reduces operating cost.
Environmental Conditions in which the Motor operates
Environmental conditions in which the motor operates must be considered for higher performance and longer lifespan because environmental conditions in which the motor operates has significant impact on its performance and lifespan.
Conclusion
Hope, you have clearly understand about the different factors affecting the selection of an electric motor. Make sure to leave your opinion and suggestion about this in the comment section below.
