Typical approach
1. Prepare to make the reference measurement. Freely suspend the motor according to
IEC60034-14.
The natural frequency of the motor-spring system must be less than 3 Hz. As a consequence,
use springs that are adapted to the motor mass. The motor must be freely suspended so that
the reference measurement can provide a correct measurement result.
2. Make a reference mark on the shaft (DE) for the speed and angle detection.
