The present paper proposes an air drive spindle that uses supplied air flow for driving and supporting the spindle rotor. Inside the spindle rotor, air flow channels are designed so that the supplied air flow in the channels generates torque to rotate the spindle rotor. This structure of the spindle can be used as an air drive motor. The designed spindle performance was evaluated experimentally. The experiment shows that the spindle rotates successfully over 18,000 rpm by giving air flow of 100Nl/min, although excessive air leakage flow, approximately 75% of the supplied air flow, was measured.
