- •
Experiments are conducted on an epicyclic gearbox with a seeded planet tooth fault.
- •
A low DOF model of an epicyclic gearbox with tooth profile faults is introduced.
- •
Simulation shows that fault signatures appear in the currents of a connected motor.
- •
The synchronous average of currents method is updated for epicyclic gearboxes.
- •
Experiments and simulations show that the method can extract planet fault signatures.
