Advantages & Disadvantages of Electric Motors

Advantages Of Electric Motors

Electric motors have a number of advantages when compared to traditional engines. The initial cost of an electric motor is much lower than a fossil-fuel engine with the same horsepower rating. Electric motors have relatively few moving parts, which means they have a longer lifespan.

Typically, an electric motor that is properly maintained offers up to 30,000 hours of operating life without needing major repairs. Overall, electric motors require minimal maintenance service.

Disadvantages Of Electric Motors

There are some disadvantages, though, with electric motors. For instance, many large electric motors are not easily portable, and consideration must be made for the correct electrical supply and voltage. Sometimes expensive line extensions are necessary in remote locations where existing electrical power is not available.
 

Also, if you are using a high-horsepower motor and a low load factor, you might have a high cost per hour of operation. Generally, an electric motor performs more efficiently and for less when compared with other engines.
