Abstract
A downhole motor includes a primary fluid path between a housing and a rotor and a secondary fluid path between the rotor and a stator. Fluid is diverted from the primary fluid path through a secondary inlet to the secondary fluid path to lubricate the motor. A magnet is located proximate the secondary inlet to bias magnetic particles in the drilling fluid away from the secondary inlet.
