Converting from DC to AC brings many benefits. This customer understood that the total cost of a new AC motor and new VFD was less than the cost for a typical DC motor rebuild. That alone was a driving force in their decision. However, that’s just ONE of the benefits in this case study.
- LESS EQUIPMENT
- The AC motor does not require a tachometer for speed control in this application so there is a reduction in cost and one less major component leading to greater reliability.
- LESS MAINTENANCE
- The maintenance on the new AC motor and Drive is fraction of the DC Motor and DC Drive, a reduction of 85% to 90% less maintenance.
- GREATER RELIABILITY
- The AC motor will have far greater meantime between failure (MTBF) due to reduced components, circuits/windings, and wear/consumable components.
- BETTER SAFETY
- We were able to design the motor as vertical, so it has proper lifting provisions to stabilize the machine during install. This greatly aids safety for the technicians.
- INCREASED MOBILITY
- The AC motor weighs less than 60% of the DC motor so it is much easier to maneuver.
