Claims
- 1. A rotor for a permanent magnet motor, the rotor comprising: a rotor shaft having:a working region for delivering mechanical energy; and a rotor region arranged coaxially with said working region, said rotor region having a rotor region surface having a rotor region continuous helical surface cut therein, the continuous helical cut having a depth of approximately between 0.001″ and 0.004″ into the rotor surface region; and a permanent magnet arrangement coupled by an adhesive to said rotor region of said rotor shaft for facilitating conversion of electromagnetic energy to mechanical energy, adhesion between said permanent magnet arrangement and the rotor region surface being enhanced by the rotor region continuous helical surface cut.
- 2. The rotor of claim 1, wherein the rotor region surface cut is a continuation of a working surface region cut.
- 3. The rotor of claim 2, wherein the working region of said rotor shaft has a threaded potion, and the working region surface cut is a first cut pass of the threaded portion of the working region of said rotor shaft.
