I order SEW-EURODRIVE gearmotors for a living. Here's my honest take on when they make sense, why SEW eurodrive gearbox oil specs matter, and why an MG90S servo motor or linear induction motor might be the smarter call—plus what to consider when asking 'what size VFD for 5hp motor.'
Continue ReadingA scenario-based guide to diagnosing linear actuator failures before you rush a replacement. Covers stalled actuators, drift, overheating, and when to check the SEW-EURODRIVE gearmotor or drive first.
Continue ReadingPractical notes on ordering SEW-Eurodrive gearmotors in Japan: how to read the SEW Eurodrive catalog, why servo motor controllers are separate from VFDs, spur gears, and what motors are compatible with VFD.
