摘要： An electric drive unit can comprise an electric machine with a stator and a rotor. The stator can comprise a set of phase windings. The electric drive unit can comprise an inverter for controlling the operation of the electric machine by providing AC signals to the phase windings. The inverter can be electrically coupled to the phase windings. An AC drive signal can be triggered for each phase winding of a first sub-set of phase windings such that the rotor is rotated via the phase windings of the first sub-set. A noise compensation measure can be triggered for at least one phase winding of a second sub-set of the phase windings for compensating an undesired signal effect.

摘要： A method and a circuit arrangement is described by means of which a stepper motor can be operated by an adaptive control over a large rotational speed range, including a standstill, in which the motor is electrically fixed in a specific rotational position, and with high precision and running smoothness corresponding to a specified motor current course. This is achieved essentially by the fact that the motor is operated in a low rotational speed range including a standstill with a voltage-controlled or voltage-regulated first operating mode and in a higher or high rotational speed range with a current-controlled second operating mode.

摘要： The present application is directed to an electrical converter having at least one of an active rectifier and an inverter interconnecting an electrical source with an electrical load. A method for controlling the electrical converter includes receiving at least one estimated control variable, receiving at least one outer loop control variable provided by an outer control loop and determining a control region based on a control error and selecting control parameters based on the control region. The control method then predicts at least one reference control value based on a solution of a physical model of the electrical converter. The solution is based on a constraint that minimizes a difference between the at least one estimated control variable and the at least one outer loop control variable. The control method then determines switching states of the electrical converter based on the reference control value.

摘要： A control device for an AC rotary machine includes an AC rotary machine having m sets of n-phase windings, a current detector, a power converter, and a control unit that calculates voltage commands on the basis of respective differences between a current command for the AC rotary machine and current detection values obtained by the current detector, and outputs ON/OFF signals to high potential side switching elements and low potential side switching elements of the power converter by comparing applied voltages calculated on the basis of the voltage commands with a carrier wave signal, wherein the current detector, when detecting currents flowing through the n-phase windings on the basis of currents flowing through current detection resistance elements that are inserted in series into the low potential side switching elements, obtains current detection values at two or more fixed timings over a single period of the carrier wave signal.

摘要： A motor control device includes an energization controller that generates energization control signals of a bridge driver, an ADC that samples and converts analog feedback voltages corresponding to output voltages of the bridge driver into digital feedback signals, and a zero-crossing detector that receives the feedback signals so as to perform zero-crossing detection for determining commutation timing and PWM duty of the energization control signal. Sampling timings of the ADC are switched to one of PWM on period and PWM off period according to the PWM duty. The energization controller PWM drives lower side switches of the bridge driver, and the sampling timings of the ADC are set to the PWM off period. The ADC performs an ADC process of the feedback voltage both in the PWM on period and in the PWM off period, and the zero-crossing detector adopts one of ADC results according to the PWM duty.

摘要： Methods and systems of optimizing efficiency of a motor drive or generator are provided. The methods include measuring data corresponding to input power and output power of a motor drive or generator at a control parameter and different load values. The methods include generating a three-dimensional surface model based on the measured data. The three-dimensional surface model can estimate an efficiency of the motor drive or generator at the control parameter and at unmeasured load values. The methods can include determining optimal efficiency of the motor drive or generator at the different load values and the unmeasured load values based on the three-dimensional surface model.

摘要： A motor control device of the present invention supplies a detection current to a motor at predetermined time intervals, detects a voltage between the both ends of a smoothing capacitor when the detection current is supplied, and determines whether a connector is inserted or unplugged based on a change in the voltage between the both ends of the smoothing capacitor. Furthermore, if determining that the connector is unplugged, the motor control device decreases the voltage between the both ends of the smoothing capacitor to or below a defined value by discharging the smoothing capacitor.
