Electric Motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

Electric motors were developed in the late 1800s. By 1887, the electric motor was installed on the first electric trolley system in Richmond, Virginia. By 1892, the electric elevator and control system was invented. Thomas Edison promoted DC power and built electric power transmission systems to power DC motors.

Modernizing the Industrial Steam Age

That sparked an “industrial revolution” by improving industrial applications. At the time, industrial processes were limited by power transmissions using belts, line shafts, compressed air or hydraulic pressure. With the electric motor, every machine could be powered by its own electric motor and provide easy control at the point of use.

This improved power transmission efficiency and increased safety and ease of setting up production.

Improved Efficiency Applications

Industrial electric motors eliminated animal and hydraulic power in processing grain and pumping water. The electric motor replaced the steam engines for powering locomotives, steamships, and industrial plants.

Today, the Department of Energy estimates that electric motors consume half of the nation’s electric power grid.

Advantages of AC and DC Motors

The DC motor is used for heavy-duty applications requiring high starting torque and compact design for high speed. AC motors are commonly found where precise controllers are required to boost efficiency and power output.

This is where the controller technology has advanced most appreciably in the past 20 years.

Applications for Industrial Electric Motors

1 hp to 100,000 hp electric motors are available to meet any industrial need. Asynchronous and synchronous motors and generators are available to suit specialized functions. ABB Motors are especially suited for challenging environments. Also, the motors can be vertical with high torque availability for additional power. Of course, they can operate on AC or DC power.

Examples of applications include industrial fans, blowers, pumps, machine tools, power tools, turbines, compressors, alternators, ships, rolling mills, paper mills, movers, and other special applications. There are systems that can work in highly corrosive environments such as nuclear power stations and highly aggressive environments such as corrosive chemicals and gases.
