Motor nameplate fields
Motor nameplate fields to capture before using Australian motor current, starting-current and voltage-dip calculators.
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.
