Picking an electric motor that suits one’s requirements is a daunting task because of the diverse offered in the market today. Anyone willing to buy an electric motor can purchase one from the market if they know some basics about electric motors like their type, specification, and use. The following will pinpoint significant matters which should be taken into account when picking one electric motor out of the plentiful options available in order to attain the desired goal.
Basics Of Electric Motors
An electric motor is actually a device that converts electricity into mechanical energy by applying magnetical forces. These motors can be classified into two main groups: Induction (AC) motors) and Dynmo (DC) motors. Due to the multipurpose uses of modern AC motors, they are extensively used in all fields of industries. DC motors, however, are more appropriate in precise speed control operations.
Important Thoughts
Considerations for selecting an electric motor have supply requirements, reasonable voltage and frequency output, and the environmental range and intended purpose built around the electric motor. Choosing an electric motor is an arduous process with many parameters that have to be met and supply requirements that are reasonable for the workload.
Supply Output: The output that needs to be supplied is given in terms of Horsepower (HP) or Kilowatts (kW) and the load requirements determine the sizse of the motor that is needed.
Environment Impact: Motors can be used in places with high levels of humidity, dust, and severe temperatures, therefore, specific ratings are added. The range of the environment plays a huge factor in the motor that is selected, as well as the type of application; a fan belt conveyor motor, for example. Keep in mind that these parameters also change the design and other features of the electric motor.
Efficiency Ratings: The efficiency rating of a motor focuses on its ability to save power which in turn saves a lot of money in the future. One of the many raters that define the efficiency level and performance one should expect is NEMA (National Electrical Manufacturers Association).
Control Options: Different applications might require different controls options to be programmed on the motor like driving VFDs for speed control and soft starters set for starting torque. Defining the level of control which is required assists in choosing a motor that will integrate well with the existing system.
Common Applications of Electric Motors
Electric motors are needed in various fields and for specific purposes. Some of them include:
Industrial Machinery: Electric motors are key components in production machinery like lathe tools, milling cutters, and conveyor machinery.
HVAC: Electric motors in heating and ventilation air conditioning systems electric motor drive the fans and the compressors.
Pumps: Having electric motors is essential for the operation of various pumps including water, chemical, and sewage pumps.
Transportation: Due to low emissions and cost effective operations, electric motors are widely used in electric cars and public transportation.
As for the section covering industry trends and future outlook, the use and application of technology against the backdrop of the industry’s electric motors has been changing dramatically. With the advent of automation, as well as other sophisticated technologies, there has been a growing demand for communication enabling motors. Furthermore, the concern for sustainability as well as lowering the carbon footprint has influenced the advancement of electric motors. In the future, manufacturers will focus more on eco-friendly materials, greater energetic efficiency, and even more advanced designs. The increase in the adoption of electric cars is contributing positively to the growth of high performance electric motors. Hence, it is vital for the buyers to adjust themselves towards the changes in motor technology.
As I have said, an industry trend based informed decision and understanding power needs, and application specific requires, along with efficiency, is the best way to improve efficiency and fulfill your requirements.
