Drives & Motor Control Systems

New variable frequency drives for facility upgrades, backed by the same shop that still sources obsolete SCR and DC drive parts to keep older lines running.

Edmundson Industrial covers both sides of motor control — current variable frequency drives for facility upgrades, and the obsolete SCR and DC drive parts that keep older lines running. Send a catalog or nameplate number and we confirm the model, voltage, and HP before you buy.

Independent sourcing, not an authorized distributor. We supply new-surplus, used-tested, and sourced-to-order, with condition disclosed before sale.

FAQ

Do you sell new VFDs or just obsolete parts?
Both. We source current-production VFDs for facility upgrades and the obsolete SCR and DC drive parts that keep older lines running. Independent surplus and sourcing, not an authorized distributor.
Can you match a replacement drive from an old catalog number?
Yes. Send the catalog or nameplate number and we decode the model, voltage, and HP and match a current or surplus equivalent.
Do you still source SCR firing boards and power stacks?
Yes. Legacy SCR and DC firing boards, regulators, and thyristor power stacks are a core part of what we source, including Ross Hill / NOV drilling drives.
Are you an authorized distributor?
No. Edmundson Industrial is an independent surplus and sourcing company, not an authorized distributor.
