摘要： The invention relates to a method for determining the angular position (theta) of a rotor (2) pertaining to an electric motor (1) and comprising a number of pairs of poles. Said method consists of the following steps: a pulse pattern (PM1, PM2, PM3) with a pulse duration (T) flows through at least one stator coil (7) of the electric motor (1), such that the rotor (2) does not rotate by more than 90 DEG, divided between the number of pairs of poles, during the pulse duration (T); the angular acceleration (alpha) of the rotor (2), caused by the pulse pattern flowing through the at least one stator coil, (7) is detected; and the angular position (theta) of the rotor (2) is determined by means of the correlation between the flow through the stator coil (7) and the angular acceleration (alpha) of the rotor (2).

摘要： Two sensors scan a measuring scale, which can be displaced in relation to the sensors and comprises a plurality of equidistant measuring gradation, and deliver corresponding measuring signals. The measuring signals are periodic during a uniform relative displacement of the measuring scale, essentially sinusoidal and essentially phase-shifted by 90° in relation to one another. They have an essentially identical amplitude and a base frequency that corresponds to the relative displacement of the measuring scale. During a delivery period of measuring signals, the measuring scale carries out a relative displacement through one measuring gradation. Corrected signals are determined from the measuring signals using correction values. A signal of the position of the measuring scale in relation to the sensors is determined in turn using said correction signals. Fourier coefficients are determined in relation to the base frequency for the corrected signals or for at least one supplementary signal that is derived from the corrected signals, said coefficients being used in turn to update the correction values. Said correction values contain two shift correction values at least one amplitude correction value and at least one phase correction value for the measuring signals, or part of said values, in addition to at least one correction value for at least one higher frequency wave of the measuring signals.

摘要： A low-wear sensor with little structural outlay is proposed to detect a combined linear and rotational movement. A PLCD sensor is provided for this purpose, the magnet (5) of which can be rotated about the longitudinally extended coil (2). A ring magnet is particularly suitable for this. The linear position of the ring magnet can be determined independently of its rotational movement (7) by means of the voltage induced in the coils (3, 4). Detection of the linear position is contactless and thus wear-free.

摘要： A drive system for an electric motor includes a connection for a battery, and an inverter having an input side connected to an intermediate circuit and an output side having a connection for an electric motor. The intermediate circuit includes a first thyristor connected in parallel with an intermediate circuit capacitance. The drive system may also include a rectifier having an input side connected at the output side of the inverter in parallel with the electric motor, and a second thyristor connected an output side of the rectifier. The first/second thyristor are configured to be activated by a monitor incorporated in or assigned to the drive system. In the event of a malfunction, the input and/or output side of the inverter can be electrically isolated to allow a multiply redundant armature short circuit.

摘要： A key-operated switch includes a first excitation device which generates a first alternating magnetic field and has a first inductance. The key-operated switch is constructed in such a manner that the first alternating magnetic field can be used to scan a first coding of a key, with the first coding changing the first inductance of the first excitation device. The first coding is read by the key-operated switch in this manner. The key associated with the key-operated switch has a carrier element which is not electrically conductive and is not magnetizable. Arranged on the carrier element is the first coding which is made of an electrically conductive and/or magnetizable material. As a result, the key can be scanned without wear.

摘要： In a magnetic bearing arrangement, support coils are connected in series and can be fed with a current. By coupling a point connecting the two support coils to a voltage source, the support coils can be used as actuating elements and, by feeding the support coils with voltage pulses, the inductance of the support coils can be inferred which is an indication of the position of the body to be mounted. This provides for a position control arrangement. Using one and the same support coils, both a stably controlled load-bearing capacity can thus be produced and at the same time a position sensor can be replaced.

摘要： Two analog signals are substantially sinusoidal and out-of-phase by about 90° relative to each other when an element moves in a temporally uniform manner in relation to a stationary element. The two analog signals make it possible to determine the actual position of the moving element relative to the stationary element. The analog signals have a corresponding maximum frequency when the moving element moves at a maximum speed. The signals are detected by sensor units and are fed to AD converters which digitize the signals at a scanning frequency and feed corresponding digital signals to an evaluation block that is configured as a hardware circuit, the scanning frequency of the AD converters being more than twice as large as the maximum frequency. The digital signals are fed to a computing block within the evaluation block, said computing block calculating an arc tangent that corresponds to the digital signals in real time. The evaluation block also determines corrective values for the digital signals in real time based on the digital signals.

The method comprises the following steps: a) application of a test current signal (ip) to a first (R) and a second (S) phase output of the three phase outputs (R, S, T) and isolation of the third phase output (T), when the converter (U) is activated for operation; b) respective measuring of the test signal (ip) and generation of a measuring signal (imR, imS) that is proportional to the measured test signal (ip) for both the first (R) and the second (S) phase output; c) determination of a correction value (Δg1) that is dependent on said measuring signals (imR, imS); and d) control of the converter (U) in accordance with the determined correction value (Δg1). The inventive method is used in particular in a converter for controlling a three-phase motor (M).
