Abstract: An electric machine, in particular an electric motor and/or generator, has a stator and a rotor which is designed to be permanently magnetic or to be energized in particular. The machine has at least two sub-machines. Each of the sub-machines has the same number of phases. The machine has a power output stage for each sub-machine, and the machine also has at least one control unit which is connected to the power output stages. The control unit is designed to generate a pulse width-modulated signal for actuating the power output stages. The control unit is designed to generate the PWM signal for the sub-machines such that an ascending or descending side of a PWM pulse for one sub-machine, said side representing a switching time in each case, and a pulse center of a PWM pulse for another sub-machine of the sub-machines are delayed relative to each other.

Abstract: The disclosure relates to a method for determining a rotor position of an electric rotating machine. The electric machine comprises at least one first, multi-phase subsystem and one second multi-phase subsystem, which each comprise a PWM-controlled inverter for feeding respective winding groups. The winding groups of the at least first and second subsystems are arranged substantially electrically offset from one another by 360°. In the method, voltages predefined by a controller are altered by feeding high-frequency voltages in order to attain high-frequency current changes. The current changes are then detected in that a current curve of phase currents is ascertained for each subsystem by measuring at least one first phase current and one second phase current. The rotor position is then determined depending on the ascertained current curves and the fed high-frequency voltages. The disclosure additionally relates to an electric machine which is designed for carrying out the method.

An underlying second closed-loop control circuit has an input variable which is based on the control variable or the control variables and serves as a nominal variable. A further input variable of the second closed-loop control circuit is an actual delivery-volume adjustment rate of the axial piston machine.

The data owners and data users may be patients, HSPs, or combination thereof. An IoT gateway aggregates periodically collected data into a single PHI file, extract keywords, build an encrypted index, and encrypt the PHI files before the encrypted index and PHI files are transmitted to a cloud network periodically for storage thus enable the DSSE architecture network to achieve a sub-linear search efficiency and forward privacy by maintaining an increasing counter for each keyword at the IoT gateway. Since the PHI files are always transmitted and added/stored into the cloud storage over the cloud network, file deletion, file modification is eliminated.
