Drives & Motion
Variable frequency drives, servo drives, and motion controllers regulate motor speed, torque, and positioning across the full range of industrial processes. PLC Direct supplies drives and motion hardware from leading automation manufacturers as surplus sealed, refurbished, and used, supporting replacement and maintenance of installed variable frequency drive and motion control systems across manufacturing, process, and infrastructure environments.
Where Are Drives & Motion Used in Industrial Environments?
Drives and motion control hardware are installed wherever electric motors require precise speed, torque, or position regulation across continuous and discrete industrial processes. Variable frequency drives, servo drives, and motion controllers are present across nearly every sector of industrial operations.
Facilities and operations that depend on drives and motion control hardware include:
-
Manufacturing and assembly plants running conveyor systems, machine tools, and multi-axis production equipment requiring coordinated servo drive control.
-
Water and wastewater treatment facilities using industrial VFDs for pump and fan energy optimization across distributed, often unattended sites.
-
Mining and mineral processing operations controlling crushers, conveyors, and slurry pumps with variable frequency drives sized for high-load continuous duty.
-
Food and beverage processing lines where precise variable speed drive control governs filling, mixing, and packaging equipment.
-
Oil and gas and petrochemical plants running compressor and pump drives in process-critical applications where hardware availability directly affects production continuity.
When a drive fails or reaches the end of its service, sourcing a compatible replacement quickly is essential to restoring normal operations.

What Should You Know Before Ordering Drives & Motion?
Hardware condition options: PLC Direct supplies variable frequency drives and motion control hardware as surplus sealed, refurbished, and used. Surplus sealed units are factory-sealed stock; refurbished units have been tested and restored to operational condition; Used hardware has been previously installed and carries the same 1-year PLC Direct warranty as all other condition grades.
Compatibility and part identification: Drive part numbers encode critical parameters, including input voltage, output power rating, frame size, and communication interface, all of which must match the installed motor and control system. For servo drives and motion controllers, encoder interface type and axis configuration are additional compatibility factors; confirm the installed system specification before ordering a replacement unit.
Warranty: All drives and motion hardware purchased from PLC Direct carry a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
PLC Direct supplies drives and motion hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
