An adjustment device for adjusting a relative rotational angle position of two shafts (particularly a cam shaft and a crank shaft of an internal combustion engine) that has an adjusting gear which is designed as triple shaft gear and has a drive part connected to a first shaft (crank shaft), a driven part connected to a second shaft (cam shaft), and an adjustment shaft connected to a servomotor shaft of an electric servomotor in a rotationally fixed manner. In order to implement a wide temperature range for the operation of the adjustment device, a temperature sensor is arranged in the servomotor. In a method for operating an adjustment device or an actuator, the current of the servomotor or the actuator is controlled depending on the temperature that was determined earlier.
A method of temperature-dependent regulation of energization of an adjusting device for adjusting a relative rotational angle position of a first shaft and a second shaft using an adjusting gear configured as a multi-shaft gear, comprising a driving part connected to the first shaft;
In a servomotor for an adjusting device for adjusting a relative rotational angle position of a first shaft and a second shaft using, an adjusting gear configured as a multi-shaft gear having a driving part connected to the first shaft, a driven part connected to the second shaft, and an adjusting shaft, the servomotor having a stator, a rotor, and a servomotor shaft connected to the rotor, the adjusting shaft being connected to the servomotor shaft in a rotationally fixed manner, the improvement comprising:
