A method for operating a braking system, wherein a switchable connection between two connection points is open in normal operation, and a voltage difference across the switchable connection is reduced by recuperation before said switchable connection is closed, which serves to compensate for a disturbance in an on-board electrical system. As a result, it is possible to avoid excess currents in the event of the closing of the switchable connection.

Method for operating a braking system

A method for operating a permanent magnet synchronous motor comprises setting a maximum power, determining a current vector and an output voltage vector in the dq coordinate system. A setpoint amount for a setpoint voltage vector is calculated on the basis of the maximum power, the current vector and the output voltage vector. The setpoint voltage vector is generated with the setpoint amount, and then operating the permanent magnet synchronous motor at least with the setpoint voltage vector.

Method for operating a synchronous motor excited by permanent magnets, electronic control device, motor arrangement, and storage medium

A method for monitoring an electric motor of a hydraulic brake system for a motor vehicle, wherein a first torque and a second torque are calculated and compared with one another. A fault can be detected on the basis of the comparison. The invention also relates to an associated electronic control module, to an associated hydraulic brake system and to an associated non-volatile computer-readable storage medium.

A method for driving a multiphase motor by a drive circuit, wherein the drive circuit comprises a plurality of transistors, and for each phase of the motor are provided a first path and a second path, wherein at least one transistor is assigned to the first path and to the second path of each of the different phases, and wherein a normal mode, a first drive mode, and a third drive mode are provided, wherein for the first drive mode, all the transistors in the second paths are short-circuited, and for the third drive mode, all the transistors are opened. The method includes detecting an undervoltage or an overvoltage in the drive circuit, operating the drive circuit in the first drive mode if a first undervoltage has been detected, and operating the drive circuit in the second drive mode if a second undervoltage has been detected.

A method for operating a permanent magnet synchronous motor, an operational vector being determined in a multi-stage process. A motor assembly configured to perform such a method is also disclosed.

Method for operating a permanent magnet synchronous motor, and motor assembly

A method for operating an electric machine, in which a control device assigned to the electric machine is used to switch currents of winding phases of the electric machine in a pulse-modulated manner, provides that a current value of the direct input current of the control device is determined using current values of the winding phases and duty factors of the pulse modulation.

Method and device for operating an electric machine

An electronically-commutated synchronous system and method includes a permanently-excited rotor and a stator which is provided with three phase windings, together with three rotor position sensors in an appropriate arrangement for a first commutation scheme. The rotor position is determined by the read-out of data from the position sensors. The appropriate voltage vector is defined by a second commutation scheme, and the second rotor position thus determined is compared with the first commutation scheme. If the rotor position sensors are operating correctly, the position of the rotor may be determined to an accuracy which is equivalent to the interval between two columns in the commutation table.
