Electric motors are the workhorses of industry. From pumping stations and processing plants to manufacturing lines and HVAC systems, they quietly power critical operations every day. But when a motor fails, the impact is anything but quiet. Unplanned downtime, production losses, emergency callouts and costly replacements can quickly escalate , especially if failure happens in […]
Electric motors in water and wastewater pumping stations operate under continuous duty, variable loads, and challenging environmental conditions. As a result, certain failures occur repeatedly across the sector. The most common motor failures include: Bearing Failure Often caused by poor alignment, imbalance, or lubrication breakdown. In VSD-driven applications, electrical fluting can also accelerate bearing damage […]
When an electric motor comes back online after a repair or service, most people focus on one thing: is it running? But at APDS, we’re focused on something far more important, is it running correctly and efficiently? Two of the biggest contributors to a motor’s long-term performance are on-site balancing and laser alignment. These processes […]
The APDS Motor Services team has successfully completed the replacement of a critical Air Handling Unit (AHU) at a local Hospital. This upgrade provides improved performance, reliability, and long-term efficiency for the site’s HVAC system. The project involved the careful removal of the existing motor, impeller and bed plate, followed by the installation of new, […]
During a recent bearing change on a 355kW Siemens motor, our engineer Jamie Sims uncovered something you don’t see every day – an insulated bearing journal. The bearing itself was already showing early frosting, a classic indicator of circulating current issues and a sign that more serious damage was on the way. With the motor […]
When you’re supporting vital medical research, every component of your building services infrastructure matters. That’s why, when an oncology laboratory experienced a sudden issue with one of its Air Handling Units (AHUs), the Motor Division at APDS was called in to resolve it, fast. The Problem: An overnight fault had caused the AHU to break […]
