Problem: Paragon regularly faces a multitude of challenges in the process of remanufacturing hydraulic and electronic controls.

Solution: Sometimes the solutions are straightforward, sometimes they are complete changes in the way the process is done.

For example, AC/DC Drive testing

Problem: How can you make sure that repaired AC and DC drives are ready for full service without access to the machine the device controls?

Answer: Create a test bed that can simulate a variety of conditions that literally "exercises" the newly repaired drive.

The prototype test stand pictured above uses a "trio" of electric motors to supply an AC and/or DC source for the drive being tested, as well as a mid-mounted DC motor to supply drag to the system. (Pass cursor over case to see system internals)

To perform a typical test, an AC drive is wired to a power supply at the AC motor end of the system, (or a DC drive is wired to the DC motor at the opposite end) and the drive applies voltage to the motor. To increase load on the system, the DC drag (or brake) motor is adjusted at the control console. As the drag is increased and decreased, various performance characteristics of the drive can be viewed at the console and on the nearby meters. A test set would likely be a repeated regiment from the lower limits of the drive up to the maximum design peak of the drive.

In this way, virtually any drive designed within the specifications of the test stand, can have "real-world" repeatability tested over and over until the technician is convinced that the drive will perform up to original specifications or beyond not just a simulation but an actual workout.

This specific test stand is rated at 50HP and a second test bed designed for smaller AC and DC drives is currently under construction based on this successful design.
