MotorEfficiencyCalculator

Calculate. Optimize. Save.
Without a desktop seat.

Efficiency, power factor, energy savings for industrial motors. DOE spreadsheets live in the office. This lives next to the nameplate. Not vehicle oil changes — that is MotorClarity. Not critical speed — that is CritSpeed.

See how it works

01 — The problem

The savings number is on a spreadsheet you left upstairs.

Desktop tools and manufacturer PDFs. Fine — at a desk. On the floor you have a nameplate and a clamp meter.

MotorEfficiencyCalculator is the field calc: efficiency, power factor, what a better motor might save. Offline. Not a replacement for a full energy audit.

02 — The job

One job. Put a number on the waste.

Industrial motors. Not the car in the driveway.

Efficiency

What the machine is actually doing with the watts.

Power factor

The other number the utility cares about.

Energy savings

An illustration, not a rebate promise.

Nameplate inputs

The data you can read while standing there.

Works offline

Plant wifi is not a given.

No ads. No account.

A calculator. Not a lead form.

03 — On the device

A field calc. Not a fake SCADA screen.

Real screens go here when we have captures. We will not invent a plant DCS. The product is efficiency math, on the device.

04 — Proof

On deviceNo desktop seat

NoneAccount to calculate

05 — Privacy

Nameplate data stays on the phone

kW figures are not uploaded to an energy SaaS.

No cloud — No account.
No tracking — No ad ID on a motor tag.
Fully offline — Works without internet after install.
You own the data — Delete it on the device.

MotorEfficiencyCalculator is an engineering aid. It is not a utility rebate, an energy audit, or a substitute for a qualified engineer.
