摘要： A method and an apparatus for adjustment of the rotor angle of an elevator motor (M), in which method: the rotor angle of the elevator motor is measured, the rotor angle is adjusted by using the measured rotor angle value as feedback data, and the rotor angle is measured by means of a pulse emitter (PE) or tachometer connected to the elevator motor. In the method, a disturbance signal (u) is fed into the rotor angle feedback data to produce a change (disturbance) in the rotor angle, the change (disturbance) is compared to the disturbance signal (u), and, on the basis of the comparison, a control signal is generated to adjust the rotor angle.
