ABB's Electric Motors Vs. Eaton's Hydraulic Motors

Mike Jeffries | March 1, 2021

There are a lot of contractors and vendors that deal in the world of motor and pumps, SCADA and automation, and electrical services.  But what makes one better than the other?  What makes one stand out among the rest?

The answer to that is whoever can achieve whatever, wherever, and whenever a specific application is needed.

What kind of electrical service is needed and who offers that specific need?  Can a contractor fulfill an order of the amount and type of PCL sensors that are required?  Is the application site where motors are going to be installed at extreme temperatures, very humid, or a high altitude?

If there is a comparison to be made between two contractors, say, ABB and Eaton, there are many things to consider. 

Yes, both ABB and Eaton offer up products and services for motor and pumps, SCADA and automation, and electrical services.  But, the big difference between ABB and Eaton is that ABB provides electrical motor products and services and Eaton provides products and services related to hydraulic motors.

The Basics of ABB’s Electric Motors

ABB provides standard designed or highly customized high voltage induction motors, rib cooled motors, modular slip-ring motors, and modular welded frame motors with different cooling options.  They also provide IEC low voltage motors for HVAC, water, and wastewater applications.

They supply electric motors such as general-purpose motors, brake motors, smoke extraction motors, and stainless steel, food-safe motors that are used for food and beverage applications.

Also available are motors for cement and mining, roller tables, and marine-related purposes.  The point is they have a motor to fit every need.  They
even have a motor for "explosive atmospheres" or explosion-proof motors.

Hydraulic vs. Electric Motors

Eaton, however, caters to the hydraulic motor and pump industry, and the motors they provide are hydraulic as opposed to electric.  

That's not to say there aren't any advantages to hydraulic motors in certain applications.  This type of motor uses liquids such as oil which contributes to tighter control of the motor and accuracy in movement.  

Because of that, this type of motor would be great in trucks and mobile heavy equipment such as loaders or cranes.  But, the applications in which this particular motor can be used do seem limited.

The disadvantages of hydraulic motors are that they are pricier than the electric motor and can be messier because of the amount of oil needed to operate a hydraulic motor.

The advantages of an electric motor are that most hydraulic set-ups are not quick. Electric motors are much faster and they have programmable speeds and stop positions, unlike hydraulic motors. 

Also, there seems to be a bigger market for electric motors and more room for adjustment when applying it to a certain requirement.

The disadvantages of an electric motor are that they are difficult to install and troubleshoot and the more force that is required, the bigger the motor that is required, and the more space is needed.
