An electric machine includes a stator, a rotor, a printed circuit board having at least one sensor configured to detect a position of the rotor, and a system configured to arrange the at least one sensor in different positions on the stator relative to the stator.

Method and apparatus for detecting the position of a rotor in an electric machine

An electric motor includes a stator, and a rotor which has a rotor shaft. At least one rotor position magnet is disposed on the rotor shaft, and is configured to provide a magnetic signal that can be evaluated, upon a rotation of the rotor shaft, at least for the purpose of determining a respective rotor position of the rotor. At least one carrier is disposed in a rotationally fixed manner on the rotor shaft, and is connected to the at least one rotor position magnet. The carrier includes at least one opening configured to compensate imbalance of the rotor.

Electric motor having a stator and a rotor

A method for operating a microcomputer apparatus includes provisioning an electrical reference voltage that is independent of an electrical supply voltage, continuously comparing a defined level of the electrical reference voltage with the electrical supply voltage, and performing a defined operation with the microcomputer apparatus for at least one defined ratio between the defined level of the electrical reference voltage and the electrical supply voltage. The provisioning and the continuous comparing involves using a functional module of the microcomputer apparatus.

Method for operating a microcomputer apparatus

A method for checking a speed system of a motor-driven apparatus is proposed. In the absence of a speed signal, a first aspect provides for a control device to send a test signal via the speed system, the test signal being expected at an input of the control device. If the test signal is not detected, a fault in the speed system is identified.
