DC Motors and Drives vs. AC:  Checklist for Your Application

Are you a manager/owner of a facility that requires the use of heavy duty motors and drives?  Whether you need to install all new motors and drives for a brand new operation or upgrade older ones to make your facility run more efficiently, you might already realize how difficult it can be to choose between AC and DC motors and drives.  It can be tempting to just upgrade to all AC motorsbut that might not be the most economical choice in the long run.  Therefore, it’s best to choose based on certain criteria. 

Here’s a brief checklist to help you decide between AC and DC motors and drives:

1.  Consider Total Expense

Determine the total cost of replacing an older DC motor and/or drive versus buying a new AC motor.  Total cost for purchase, installation, future maintenance, and operation should be considered.

 

2.  Compare Features for Both

DC motors and drives have been around for quite a while; however, these have been upgraded with the latest features to make them more efficient in the work place.  DC drive features such as accel/decel adjustment selections, preset speeds and jog speed, speed reference, dated fault log history, multi-function outputs, electronic motor overload protection, feedback options (tachometer, armature), and more make it easy to select either an AC or DC motor and drive for a variety of applications.

3.  Dependability

Are the motors and drives easy to replace and/or repair should you need to do so in the future?  Is technical support readily available during and after installation?  If ordering out of the country, do the motors/drives meet international regulations such as EN, IEC, CSA, UL, etc.

Also consider how the new motors and/or drives will affect the surrounding work environment.  Consider heat dissipation, space availability in comparison with the space that’s going to be required for proper installation, and other factors before deciding.
