Motor characteristics (Direct Drive Brushless Motor)
CAUTION
High RMS current will generate motor heating which will degrade
characteristics of the stage, such as repeatability, accuracy, etc…

NOTE
The values above indicate voltage induced by energized coil of one
phase on next phase coil. A positive value for U-V would indicate a
higher voltage on U relative to V.
