Motor nameplate fields
Motor nameplate fields to capture before using Australian motor current, starting-current and voltage-dip calculators.
Motor nameplate fields keeps motors and transformers table values traceable for Australian records. Show which motor nameplate values belong beside motor current calculations. Check the source, last verified date (13 July 2026), Australia; product data, starter selection, protection and project requirements can override general notes., and the current project documents before carrying any row into a calculator or design note.
Nameplate fields behind motor current checks
Show which motor nameplate values belong beside motor current calculations.
| Field | Use | Check | Boundary |
|---|---|---|---|
| Rated kW | Real power input for FLC estimates. | Confirm shaft/output context on the nameplate. | Do not infer efficiency if not known. |
| Voltage and phase | Sets current formula basis. | Match the actual supply arrangement. | Do not mix single-phase and three-phase values. |
| Nameplate current | Comparison value against calculated current. | Use the nameplate value where present. | Nameplate current often outranks a formula estimate. |
| Power factor and efficiency | Improves current estimate. | Use product data if available. | Assumptions can shift current materially. |
| Starting method | Supports 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.
| Item | Value |
|---|---|
| Purpose | Show which motor nameplate values belong beside motor current calculations. |
| How to use the source | Field table only; motor formulas live on calculator and chart pages. |
| Standards and project context | Australian project context; product data and manufacturer instructions govern motor records. |
| Where judgement is still needed | Use this table for lookup, labelling or worksheet context; do not treat it as a project-specific calculation result. |
| Before relying on it | Confirm 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.
