摘要
The present disclosure is generally directed to techniques for radial alignment of motor components relative to each other to achieve a motor with a rotor bore having sub-micron end-to-end deviation. In an embodiment, a rotor bore alignment tool is disclosed herein that can be inserted between motor components, and more particularly, apertures/through holes defined by each of the motor components such as housing sections and a stator assembly. The rotor bore alignment tool includes expandable members that can be selectively transitioned to an extended position to cause each of the motor components to be radially aligned prior to securely coupling the same in a so-called “stack” to form a motor. Once the motor components are coupled together, the resulting motor includes a rotor shaft extending from end-to-end that preferably includes a sub-micron deviation of less than 10 microns, and more preferably less than or equal to 5 microns, for example.
