Replacing DC motor with AC motor and AC VFD

Customers of Precision Electric who operate DC drives and motors often inquire about replacing and upgrading their DC equipment with AC equipment. To help users faced with this dilemma, I have decided to post about the topic.

Of course, the main advantages of DC drives are that they cost less, produce less heat, have smaller footprints and are easier to fix in the field. They also can perform high torque at low speed and handle high-impact loads. However, the main knocks against DC drives are that the motor costs more and requires some maintenance, and they need a field supply, which adds complexity.

DC drive systems also require accessory equipment, such as inductors, contactors and fusing, and many users are increasingly unfamiliar with DC technology.

Meanwhile, the advantages of AC drives are that they’re used with AC induction motors, so there are no brushes to maintain, and the price of an AC drive system, including the motor, is more cost-effective than a DC drive. AC drives also have better power factors, are easy to install and start up, are available from multiple vendors and can run motors efficiently across the whole speed range.

However, the disadvantage of AC is that the drive is fundamentally more complex, involving volts and amps and hertz. Also, line regeneration is possible, but expensive, and brake choppers are sometimes necessary, but they waste energy and give off heat.

Despite these many differences, there are some areas where DC and AC drives come to a tie. They also have comparable drive features, ease of commissioning when looking at state-of-the-art DC drives, as well as reliability and maintenance of the drive.

Precision Electric recommends that users replace their existing equipment with an AC system when:

  • The existing DC motor is near its end of life,
  • Power factor and distortion are an issue, such as when the DC motor has a poor power factor when running below base speed, or when you’re paying a penalty or need to add a power factor correction, or when there’s an IEEE 519 requirement;
  • The motor is small, perhaps less than 200 hp, so the money difference becomes insignificant given the many benefits that will be gained with an AC system; and
  • The machine can be out of service for a longer period of time.

Users should upgrade their DC drives when:

  • You want to save money, as when the DC drive replacement costs less than AC system replacement throughout the HP range;
  • The existing DC motor is in decent shape, and spares are readily available;
  • Your situation requires fast upgrade with minimal downtime.

Users also should consider a DC drive or system replacement for large motors, especially above 1,000 hp or above 690 volts; if they have a large regenerative load; or if their DC motor is not easily replaceable with an AC motor. This may be because of differing shaft height and shaft diameter, difficult position or hard-to-reach components, or if they their application has special cooling needs.

If you are considering replacing your DC equipment with AC equipment and are unsure about your decision, call or email us. Precision Electric has been serving the industrial manufacturing world for over 25 years and has over 100 years of combined experience in the field.

DC Electric Motor Repair Services

We’ve Been Servicing the Industrial World Since 1983.

Minimize Your Downtime. Maximize Your Productivity.

Call Toll Free: 1.877.625.2402


Precision Electric has hundreds of years combined experience in DC electric motor repair, including armature and field frame rewinds. We service a wide variety of industrial customers and also provide services to other motor repair centers across the midwest.

DC motors introduce additional complexities into the repair process. The addition of a commutator with brushes, and rotating armature coils subjected to centrifugal force, which aren’t factors involved in typical AC electric motor repair.

The following procedures and tests are used at Precision Electric to ensure top-quality DC machine repair:

  • Conductive carbon dust left by worn brushes is cleaned from the armature; then each commutator is checked for grounds and bar-to-bar shorts with detailed electrical testing.
  • Technicians repair most commutator problems in-house. For severely damaged or non-repairable commutators, we outsource for fast delivery of custom manufactured replacements.

  • Coils are manufactured in-house to assure proper fit. This eliminates constant bending and shaping during installation which can damage coil insulation.
  • Proper banding is critical in DC repair. This ensures that windings are held in position during high-speed operation.
  • Field coils are checked using voltage drop testing. Bad fields and interpoles are rewound in our shop on custom forms.

  • TIG welding is available to eliminate soldered joints where design dictates.
  • All commutators at Precision Electric are turned, undercut, and chamfered to provide the best possible surface for brush contact.
  • For corrosive or other severe duty environments, commutator platinum plating is available to extend wear life (pickle-duty).
  • Neutral setting adjustments are made during final machine testing to insure proper operation.

 

The Precision Electric in-service warranty is another advantage we have over our competitors. We encourage customers to have all spares rebuilt and ready for immediate replacement; this is to ensure maximum production with little to no downtime. Our in-service warranty begins the same day our customers install equipment rebuilt by Precision Electric, and ends 12 months later.

Industrial Manufacturing Infrared Thermography Services

Infrared inspections provide a means to view systems (electrical, mechanical, building envelopes) under normal operating conditions to identify abnormally hot (or cool) areas or components. This is a powerful maintenance tool. In many instances, equipment failure is preceded by a period of increasing heat. This is especially true of electrical equipment.

With infrared thermography you can identify overheating electrical connections and other machine components, scheduling repairs to be made during planned downtime. This increases reliability and productivity for the entire operation.

This thermogram shows a loose connection of the lug on incoming power supply. Operating equipment with loose connections can
cause many problems, some damages could be un-repairable

Financial Savings

  • Fewer interruptions while in operation mean more uptime and greater productivity.
  • Equipment problems are fixed before they fail and damage or destroy the rest of the machine.
  • Identifying developing problems and planning the repairs results in fewer panic situations, those costly predicaments that force excessive overtime and monetary premiums for emergency rush equipment orders.

This thermogram shows a loose fuse clip that needs tightened or replaced. Loose fuse clips could lead to serious equipment damages.

Safety

  • An industrial process that runs reliably and without surprises produces a safer work environment. Many industrial processes are complex and run at high speed. A sudden failure on one machine can have a cascading effect of failures that may include flying debris.
  • Fire avoidance. Overheated electrical connections can start fires. You may have heard of a fire in your area that it was caused by faulty wiring. This means many things including bad design and overloaded circuits. It also commonly means a bad electrical connection that was overheating and was not found in time.

Other advantages of thermography:

  • Shows a visual picture so temperatures over a large area can be compared
  • Able to find deteriorating: (higher temperature components prior to their failure)
  • Measure or observe in areas inaccessible or hazardous for other methods
  • Non-destructive test method
  • Locate defects in shafts, pipes, and other metal or plastic parts

Call Precision Electric, and schedule infrared thermography services to prevent unnecessary damages to your industrial equipment.
