Motor Energy Consumption Calculator

How Motor Energy Consumption works

The calculation uses energy = power × time. Motor Energy Consumption uses Average input power, Operating time to report Motor energy. Locked-rotor kVA belongs in the separate Locked-Rotor kVA worksheet.

With the loaded values, motor energy evaluates to 85.00 kWh. Keep other entries fixed when exploring a measurement range.

Inputs for Motor Energy Consumption

Average input power and Operating time belong to Motor Energy Consumption. Keep source units with average input power.

The opening values are placeholders for testing the arithmetic. Use Motor Torque Calculator to a separate shaft torque calculation.

Average input power

Example entry: 8.5 kW.

Operating time

Example entry: 10 h.

Reading the Motor Energy Consumption result

This output represents Motor Energy Consumption.

Do not treat the calculated number as a component rating by itself. Check standard sizes, transients, protective margins, and manufacturer limits. For estimated power after speed reduction, use VFD Energy Savings Calculator.

Measurement and units

Motor nameplate data, duty, enclosure, starting method, load profile, and thermal limits govern final selection. Check prefixes on average input power. Acceleration time can be checked in Motor Acceleration Time Calculator.

Scenario differences are meaningful only with consistent units and observation points.

Limits of this calculation

Use a load-profile average for cycling equipment.

This equation represents one relationship rather than a full circuit simulation. Unentered effects remain outside Motor Energy Consumption.
