Abstract: A method for controlling a three-phase AC motor, wherein the three-phase AC motor has a rotatably mounted rotor and a stator including a first group of coils and a second group of coils. Each of the coils generates an oscillating magnetic field upon actuation using an alternating current. The phases of the alternating currents are selected such that the superposition of the magnetic fields of the first group of coils generates a magnetic rotating field that rotates with a direction of rotation and the superposition of the magnetic fields of the second group of coils generates a magnetic rotating field that rotates counter to the direction of rotation. A system composed of a three-phase AC motor and an inverter for carrying out the control method is also described.

Abstract: A portable appliance detects explosive materials. An indicator has a carrier and a plurality of indicator substances arranged in different regions to represent a location dependent pattern. The indicator substances are a thin layer positionable in an indicator area by a holding apparatus. A plurality of radiation sources emit quasi-monochromatic excitation radiation and are arranged at various locations in a radiation area so as to represent a location dependent pattern of radiation sources. An excitation beam path with a first imaging system images excitation radiation into the indicator area such that emission of the indicator substances is producible at the imaging locations on the indicator area. An emission beam path with a second imaging system images the indicator area into a reception area such that a pattern of emissions is producible depending on the location. Receivers receive emissions from the reception area and convert them into electrical signals.
