Nameplate fields behind motor current checks

Show which motor nameplate values belong beside motor current calculations.

Motor nameplate fields
FieldUseCheckBoundary
Rated kWReal power input for FLC estimates.Confirm shaft/output context on the nameplate.Do not infer efficiency if not known.
Voltage and phaseSets current formula basis.Match the actual supply arrangement.Do not mix single-phase and three-phase values.
Nameplate currentComparison value against calculated current.Use the nameplate value where present.Nameplate current often outranks a formula estimate.
Power factor and efficiencyImproves current estimate.Use product data if available.Assumptions can shift current materially.
Starting methodSupports starting-current review.Confirm DOL, star-delta, soft-starter or drive context.Starting behaviour is product and installation dependent.
  • Nameplate values should travel with calculator results.
  • Product data and starter design can override generic assumptions.

Before nameplate data enters a calculation

Capture the rated voltage, current, power and efficiency context before comparing calculated current with the motor record.

PurposeShow which motor nameplate values belong beside motor current calculations.
How to use the sourceField table only; motor formulas live on calculator and chart pages.
Standards and project contextAustralian project context; product data and manufacturer instructions govern motor records.
Where judgement is still neededUse this table for lookup, labelling or worksheet context; do not treat it as a project-specific calculation result.
Before relying on itConfirm current standards, local authority requirements, DNSP conditions, project documents and manufacturer data before relying on a decision.

Product record basis for motor fields

Review the motor nameplate or product record, checked date and Australian project scope before relying on these fields.
