# Microgram: actuator-systems-detect-motor-fault

`station__algovigilance__microgram-actuator-systems-detect-motor-fault` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Detect motor/actuator faults from sensor readings. 7 fault types: winding overtemp (critical/warning), overcurrent (critical/warning), encoder loss, stall, phase imbalance. Returns fault type, severity, and recommended action.

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown

## Input schema

- `phase_current_a` *number* (required) — RMS phase current in amps
- `winding_temp_c` *number* — Motor winding temperature in Celsius
- `rpm` *number* — Current motor speed in RPM
- `encoder_valid` *boolean* — Whether encoder feedback is valid
- `phase_balance_pct` *number* — Phase current balance percentage
