A method for sensorless control of a separately excited synchronous machine having a rotor includes the following steps: feeding a test signal on a parameter of an electrical current driving the rotor; measuring the parameter of the electrical current driving the rotor on an axis of the coordinate system describing the synchronous machine; determining an error signal by correlating the measured parameter of the electrical current driving the rotor with a temporally delayed test signal which is determined from the fed test signal; and adjusting a rotor angle as a reaction to the error signal if the error signal has a value not equal to zero.

A rotation angle detection apparatus includes an incremental rotary scale and a detector. The rotary scale includes both a detection region having a scale formed therein for detecting a rotation angle of an object and a non-detection region having no scale formed therein. The detector generates, based on an input signal indicating change in the position of the scale of the detection region which changes according to change in the rotation angle of the object, an electrical signal that periodically changes according to the change in the position of the scale of the detection region. Further, the detector detects the rotation angle of the object based on the electrical signal. Furthermore, the detector detects a reference angle for the rotation angle of the object by counting the number of positional changes from an end of the scale of the detection region; the positional changes are indicated by the input signal.
