A cutaway electromechanical actuator reveals motor rotor, gearing, leadscrew, carriage and position sensor. Inject a jam, a broken coupling or a biased sensor and distinguish motion, command and measured feedback.
• 3D scene parts: Motor rotor / stator; reduction gear / coupling; leadscrew; guided carriage; position sensor. • Controls: Injected failure mode (Normal, Mechanical jam, Broken coupling, Sensor bias); Commanded motor speed (30–120 rpm); Sensor bias (0–30 mm). • Live readouts: Actual carriage position (mm); Measured position (mm); Illustrative motor-current proxy (relative); Sensor measurement error (mm). • Guided experiments: Coupling broken; Biased feedback. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
Gear reduction = 3:1; screw lead = 20 mm/rev Travel rate = 20 × motor rpm / (3 × 60) mm/s u = (travel rate × t) modulo 200 mm Nominal position = u if u ≤ 100, otherwise 200 − u Jam / broken coupling: position = 0; sensor bias: measured = actual + bias
Representative electromechanical teaching example: 3:1 ideal reduction, 20 mm/rev lead, 100 mm reciprocal travel. Reversal is instantaneous; no acceleration, inertia or solved control loop. Current is a dimensionless diagnostic proxy, not calculated motor current. Geometry and playback are illustrative; no equipment qualification is implied. Try the preset experiments, then compare the live readouts with the equations.
No. The stated model omits real qualification evidence and system-specific assumptions.
Distinguish mechanism, local effect and system effect.
