Machine design and adjustment of the phase angle
Each rotation of the mounted rotor induces the 3-phase EMF of the motor in the stator phase
windings. When the master and stoker operate in parallel, the phase angle of each stoker
EMF must match the phase angle of the master EMF.
To adjust the phase angle, the stator and rotor each have a reference mark on their face
sides. The reference marks of the motors are shown in Chapter "Installation
drawings/Dimension drawings (Page 519)".
● The reference mark in the stator depends on the motor article number.
