DC SRC/thyristor drives and motors remain common in industries, such as metals, cranes, mining and printing. The current trend is to replace DC systems with new AC drives and motors to reduce maintenance overheads, however, this can often be a significant task that requires the machinery to be taken out of service for an extended period while mechanical and electrical rework is undertaken.
Utilizing the existing DC motor and upgrading the DC drive is often the most attractive option. DC motors are usually well built and capable of offering many more years of service, the project costs are usually much lower and the disruption and risks are minimised. Modern DC drives also provide many benefits, Control Techniques DC drives are based on our current AC drive technology, they offer enhanced motor performance, reliability and system integration options.
