Abstract: An electric machine for use within the powertrain of a hybrid or fully electric motor vehicle includes a stator and a rotor, said stator and rotor being received in an engine housing. The engine housing has at least one A-bearing shield and at least one B-bearing shield (6) for supporting the rotor relative to the engine housing, wherein the A-bearing shield and/or the B-bearing shield has/have a multipart design, in particular a two-part design, in each case comprising a respective annular inner shield and an annular outer shield, and the inner shield is arranged radially within the outer shield such that an annular space is formed between the inner shield and the outer shield. A connection shield is at least partly arranged in the annular space so that the inner shield and the outer shield are secured in the radial direction by the connection shield.

Abstract: A device for measuring the temperature of a coil device in an electric machine having a temperature sensor, a first section which produces a first restoring force, a second section which receives the temperature sensor, a third section which has a first fixing element, and a fourth section which produces a second restoring force.

Abstract: In a phase control loop, an output signal which is used to control an oscillator in a PLL or a phase-delay device in a DLL is generated by means of a phase/frequency detector. In accordance with the invention, the oscillator or the phase-delay device is controlled by means of a control signal which is made up of a controlling component and an adjusting component. The controlling component is generated as a proportional function of the output signal, whereas the adjusting component is generated as a proportional function of the low-pass-filtered output signal. At low frequencies, the loop gain is higher in this case for generating the adjusting component than for generating the controlling component, which means that the output signal and the component parts through which it passes can be operated at their optimum operating point, at the centre of the range of variation for example. The adjusting component may be generated by both analog and digital procedures.

Abstract: A method and a device for controlling an oscillator (1) are proposed, wherein a first control signal (b) is generated depending on an output signal (e) of the oscillator (1) and on a first reference signal (a), and a second control signal (d) is generated depending on the first control signal (b) and on a second reference signal (c), and wherein the oscillator (1) is subjected to the first control signal (b) and to the second control signal (d) and generates the output signal (e) with a frequency dependent on the first control signal (b) and on the second control signal (d). A low-noise phase locked loop with a large possible frequency range can be realised by such a method and such a device.
