VFD retrofit and motor controls for working equipment.
Mithril scopes and implements practical VFD retrofits: failed drive replacement, speed-control upgrades, ramp tuning, control-box cleanup, parameter backup, and startup notes a maintenance team can use. Best fit is existing equipment with motors, wiring, sensors, switches, or operator controls that need a bounded repair or upgrade path.
Drive replacement
Replace failed or obsolete drives with available parts and documented settings.
- major drive brands
- available replacement drives
- nameplate and load review
Speed-control upgrades
Add variable speed where fixed-speed starters create process or handling problems.
- pumps / fans / conveyors
- ramp and torque notes
- operator controls
Startup notes
Leave parameter lists, wiring notes, and failure context for future service.
- parameter backup
- fault history
- handoff checklist
Send evidence
Photos, model numbers, symptoms, nameplates, existing drawings, and what good looks like.
Bound the problem
Separate controls, mechanical, sourcing, field, and licensed-review work before parts are ordered.
Build handoff path
Leave notes, settings, files, and checklists that operators and technicians can actually use.
Related machine and controls support
Control panels and VFD integration
Panel, drive, pump, skid, and operator-control work.
Machine repair and retrofit
Repair legacy controls, motors, sensors, and handoff notes.
PLC and HMI upgrades
Small controller, I/O, alarm, and screen cleanup.
Conveyors, augers, and feeders
Material-handling controls, jam response, sensors, and motor starters.
