1. A downhole motor comprising:
a stator;
a rotor configured to rotate relative to the stator;
a body connected to the stator having an outside surface and a longitudinal extent;
a drive connected to the rotor and disposed in the body, the drive configured to rotate within the body and configured for connection with a downhole device to be driven;
a first flow passage defined between the body and the drive and disposed along the longitudinal extent of the body; and
a second flow passage extending from the first flow passage to a channel at the outside surface, wherein a Bernoulli suction force is created at the channel.
