Engineering notes
Short technical notes on pressure stages, filter cleanliness, cartridge valves and gear pump selection.
From SG90 servo motor specifications to HYDAC cartridge valve catalogs: a motion control quality inspector compares servo vs stepper motors, brushless motor tradeoffs, and why total cost beats the lowest quote.
2026-08-10 / HYDAC Engineering DeskA procurement manager explains how a small HYDAC order turned into a bigger supplier relationship, and why the HYDAC filter catalog helped with induction motors, furnace motors, and bevel gears.
2026-08-10 / HYDAC Engineering DeskNeed to choose from the HYDAC cartridge valve catalog or spec a gear coupling and stepper motor linear actuator? What's a stepper motor? A quality manager explains three scenarios.
2026-08-07 / HYDAC Engineering DeskAn emergency repair specialist with 200+ rush orders explains what VFD means (Variable Frequency Drive), how to use the HYDAC cartridge valve catalog under pressure, and which HYDAC gear pumps and brushless DC motor controllers are worth the overnight freight.
2026-08-07 / HYDAC Engineering DeskA practical guide to urgent sourcing for HYDAC cartridge valves, servo motor gearboxes, stepper motor controllers, and VFD sizing. Four scenarios from a supply coordinator with 200+ rush orders.
2026-08-06 / HYDAC Engineering DeskA quality engineer explains what happens when a linear actuator fails, and why the HYDAC filter catalog plus correct AC induction motor selection—single phase induction motor or three-phase—matter for prevention.
2026-08-06 / HYDAC Engineering DeskA quality manager compares 3 phase AC motors vs AC servo motors on speed, torque, feedback, and VFD sizing. Includes a practical answer to what size VFD for a 5HP motor and why HYDAC logo traceability matters.
2026-08-05 / HYDAC Engineering DeskA procurement manager shares the 7-point checklist they run before ordering HYDAC gear pumps, electric linear actuators, or servo motors — covering specs, failure modes, manual verification, and the TCO math most buyers skip.
2026-08-05 / HYDAC Engineering DeskA practical, field-tested checklist for sizing a VFD for a 5HP motor, choosing industrial components, and avoiding expensive mistakes. Covers HYDAC industrial components, NEMA 23 stepper motors, and gear couplings.
2026-08-04 / HYDAC Engineering DeskA HYDAC quality compliance manager shares what 4 years and roughly 800 inspections taught him about ball bearings, servo motor controllers, hobby-grade MG995 servos, and why the catalog matters more than the price.
