Method for determining initial position and wiring mode of motor rotor

The invention provides a method for determining an initial position and a wiring mode of a motor rotor. The method is applied to debugging of a three-phase motor with a rotary transformer and wiring errors, and the initial position comprises an initial potential angle and an initial potential angle phase. The method comprises the following steps: providing a plurality of wiring modes of wrong wiring types; respectively providing an initial potential angle phase difference value and an initial potential angle difference value corresponding to different wiring modes when the factory potential angle phase is the same phase and the factory potential angle phase is the opposite phase; when the initial position is known and the wiring mode is unknown, calculating an initial potential angle phase difference value and an initial potential angle difference value, and searching a corresponding wiring mode; when the wiring mode is known and the initial position is unknown, searching a corresponding initial potential ang
