Hello, I am seeking assistance with identifying and operating a BBC Veritron DC Drive that is currently unmarked with no identifying plates. I am unable to determine the specific type of drive and am in need of a manual for operating, configuring, and testing purposes. The drive is experiencing issues with powering three DC motors despite receiving AC power from a 2-phase 400V/200V transformer. I require guidance on troubleshooting and establishing the necessary conditions for the drive to function properly. Any advice or recommendations on resolving this issue would be greatly appreciated. Thank you in advance for your assistance.

In response to a query by BryanG, I found the answer on the PLC forum here: http://www.plctalk.net/qanda/showthread.php?t=67640. I discovered this forum while researching, but the drive mentioned is not the same type as mine. My motors have 6 terminals - 2 for current, 2 for tacho, and 2 for thermal. This drive has outputs for the rotor and stator - can you explain how it works? I must admit, DC motors and thyristor drives are quite complex subjects for me.
Verify if the engines are equipped with permanent magnet fields.
Reflecting on the past, it appears to be a vintage DC Single Phase drive from the late 1950s or early 1960s, marking the shift from vacuum tubes to solid state technology. The motor in question sounds like a series wound DC motor with only two power connections, A1 and A2 (or A+ and A-). It is crucial not to disconnect the motor from the load for testing, as this could lead to detrimental outcomes. Based on your description of the power source, it seems likely that it is a single-phase system rather than two-phase. Two-phase power was utilized briefly in the northeastern United States before World War II, with the transition to the current 3-phase system we use today. While some may refer to single-phase 120/230V systems as 2-phase, it is technically still single-phase. If provided with a clearer image of the board terminals, I may be able to offer more assistance. Consider upgrading the drive to a newer model or switching to an AC motor with a Variable Frequency Drive (VFD) for enhanced efficiency and performance in the long term.
The merger between BBC and Asea leading to the establishment of ABB occurred in 1988, well before the digital revolution took off. It's been almost 30 years since that merger, and it's unlikely that any information about the drive has been digitized and maintained online for over two decades. As a result, finding the necessary parts to repair it may prove to be a challenge. It may be time to consider replacing it with a more modern alternative.
Hi, I've faced similar issues with a BBC Veritron DC Drive in the past. As you've noted its markings are faded, identifying the exact model can be a bit tricky. However, you might be able to find some clues on the PCB or the circuit board. As for the user manual, it's challenging to provide without knowing the specific model but I'd suggest looking up online forums and websites dedicated to vintage electronic equipment; these often share manuals and troubleshooting guides. Regarding the problem with the motors, a potential solution could be checking the DC output with a multimeter. If there's voltage present but the motors aren't running, it could potentially be a problem with the motors themselves. Hope this helps!
Hello, The lack of identifying plates indeed makes it a bit tricky, but don't worry, we've all faced such conundrums before. First off, I'd recommend you to check if there are any serial numbers or any other indistinct markings that could help in identifying the exact model. Often, these can be found in less conspicuous areas of the drives. Try contacting ABB (the company that took over BBC) as they might keep past records and could assist you better. Regarding your power issue, it might be related to individual motor loads being too high or the drive itself might be unable to regulate the load across the motors properly. Detailed diagnostic testing would be beneficial in identifying the exact issue. Unfortunately, providing a fix would be challenging without knowing the exact model. Good luck!
It sounds like quite a challenge you're experiencing with your BBC Veritron DC drive, but don't worry, there are some solutions out there. You might be able to identify the type of drive through reliable old engineering documents, blueprints, or exploded component view diagrams that might still be accessible online. Direct contact with ABB (who acquired BBC/ASEA in the late '80s) could also yield some results. They usually provide decent post-purchase support and might assist with identification and provide the needed manuals or point you to a service provider who could help. Meanwhile, the power issue might be due to the internal components like capacitors or wiring mechanism, so you may want to consult with a professional electrician or an electronics technician. Good luck and keep us updated!
Hi there, It sounds like you're dealing with quite a challenge there! If the BBC Veritron DC Drive is unmarked, tracing its model might indeed be like finding a needle in a haystack. However, you might have some luck examining and comparing the data plate often found on the exterior of these drives, which has vital information about the model. If this isn't possible, consider reaching out to the manufacturer or any professional repair services in your area that might work with BBC Veritron drives. They might be able to help you determine the model and guide you with the necessary steps. Make sure to check if there are any visible faults like discolored components or burnt smell, any of which can be signs of component failure. But remember, always approach with safety when dealing with such machinery, especially if it's connected to a high voltage supply. Good luck!
Hey there! It sounds like you're dealing with quite the challenge. One approach you could take is to check the internal components of the BBC Veritron drive—sometimes there are serial numbers or model identifiers printed directly on the circuit board itself. Additionally, try reaching out to BBC support or browsing through online forums dedicated to industrial equipment, as someone might have a manual or similar experience with that model. For troubleshooting, ensure that all connections are secure and that the transformer voltage is appropriate for the drive's input specifications. Good luck, and I hope you get those motors up and running soon!
Hey there! It sounds like you’re in a tough spot with that unmarked BBC Veritron DC Drive. Have you tried checking for any internal labels or markings once you open it up? Sometimes they can be hidden in hard-to-see spots. For troubleshooting, I would recommend starting with the wiring and connections to ensure everything is secure and correctly configured for your voltage setup. If the drive has a fault indication LED or similar diagnostic features, that could provide clues as well. As for finding a manual, I’ve had luck reaching out to online forums or directly to BBC for assistance—they might have resources for older models or be able to provide a replacement manual. Good luck, and let us know how it goes!
