About Rotorweave: Motor & VFD

Rotorweave is a native motor and variable-frequency-drive commissioning workspace for technicians, engineers, facilities teams, educators, and equipment owners.

Document the motor, drive, driven load, cable, setup limits, field checks, measured runs, and fault history in one offline project.

COMMISSIONING CONSOLE
- Readiness checklist covering lockout planning, nameplate match, mechanical inspection, protective earth, rotation, loaded current, fault history, and operator handoff
- Three-phase voltage and current capture at multiple operating points
- Current and voltage imbalance, load percentage, temperature, and run-note analysis
- Editable motor nameplate, VFD, control mode, frequency limits, ramp, carrier, and cable data

MOTOR AND DRIVE ANALYSIS
- Synchronous speed, rated slip, input power, shaft power, and rated torque
- Predicted command speed and constant V/f voltage
- Constant-torque, constant-power, and variable-torque load curves
- Recorded frequency-versus-speed trend
- Drive-output-current margin and motor-cable voltage-drop estimate

FAULT WORKFLOW
- Local asset fault history with open/resolved status
- Guided investigation sequences for overcurrent, overload, bus overvoltage, undervoltage, ground fault, overtemperature, feedback loss, and communication loss
- Native PDF report with nameplate, setup, checklist, measurements, imbalance, warnings, and fault history

ONE-TIME AND PRIVATE
- One paid download; no subscription or in-app purchase
- No login, account, ads, analytics, tracking, or developer-operated backend
- The complete sample and all core tools work offline
- Project data stays on the device unless you explicitly share a report

Rotorweave is a documentation and planning aid. Qualified personnel must follow lockout/tagout, manufacturer instructions, applicable codes, and site procedures.
