Custom Applications

Custom-Built Drive

Ivy Steel in Houston had a number of old Emerson Spectrum drives on wire drawing machines. They also had an older drive on one which was giving them a great deal of difficulty keeping repaired. The Spectrum was out of production, and never went as high in horsepower as this machine needed. We found a power bridge, and created a custom drive, complete with a Control Techniques FXM5 field regulator, using a Melltrum circuit board, which is the same as the Spectrum mother board. This drive has been running since 1996.

Navy Cable Inspection Line

There were 5 jobs total on this project. The drives pull cable from ships through a bath where the cables are tested for insulation degradation and holes. Then, the drives pay off the cable as it is rewound onto the ships. Each drive has dynamic braking installed. The system was in stalled in 1996 and continues to operate without problem today. AIM Controls had to design and install a remote operator station with quick disconnects to allow the operators to use the station required. Obviously, we can't show you pictures of the installation..

Spindle Drive

This spindle application was run on a DC motor. The drive was a Clark drive running open loop. The customer being tired of the maintenance on the motor, we replaced the drive and motor with this Saftronics drive. We also built them a new control station with a spindle current trip meter. This system was installed in 1995 and continues to run without problems today. AIM Controls gutted the existing cabinet and did the installation into the existing drive enclosure to hold down the costs.

Coater Controls

These controls were designed to allow operators to control movement of pipe to be coated in a new process. The controls handled the pipe conveyor, the coating delivery system and the haul-off system. We used EMS G5 Vector drives and motors to handle this process. The line speed was set on the master drive which then was sent to all other drives through two master reference boards. We also built the custom operator's station, to the bottom left.

Pressure Testing Machine

This customer needed a positioning system to position pipe for pressure testing. The pipe is sensed and then tracked by the drive to the proper position. Then the clamps are set and the pipe pressurized to test for leaks. Of course, this was no big deal for our experts!

Special Test Stands For Circuit Boards

Our engineers needed a way to test circuit boards for an old Wer ES300 RG DC drive. We located an old rack then created a power bridge with a shunt for current feedback. After tieing all of these components together, we were able to effectively test under load all of our customer's circuit board. This is a much more effective test than just bench testing which could miss some defects. Our technician is now testing one of the customer's circuit boards. The drive is set up to run a DC motor, allowing for dynamic testing of all components, as well as set up of such crucial regenerative drives functions such as "crossover."

Controls For Madame Butterfly (Houston Grand Opera)

The production required precision control of a multitude of screens which were lowered from the stored positions on a cue from the operator. This window shows the background American flag screens and the foreground Japanese screens. This is the cue positions for screens as the opera opened.The production required raising and lowering screens throughout the opera. Here, the actors are seated "stage front" with the foreground Japanese screens down. To the sides of the stage, "stage right" and "stage left," were also screens that were raised and lowered to keep preparations for the next act out of sight of the audience. Those screens were also controlled by the cue system designed by our software guru, Royce Mitchell, III. We used the Fincor ACX to control the screen movements. The simplicity of programming and the inexpensive price of these units and motor/gearbox combinations, helped to keep the project cost within budget. There were 17 of these units installed. They are moved around the country, and are used internationally, in the Madame Butterfly production by H.G.O. This system was installed in 1999 and is still in use!
