摘要:
In order to connect an angle measuring device to a brushless direct-current motor, a coupling is used, the coupling halves (10, 28) of which are each attached to the rotor (46) of the motor and/or the rotor (42) of the angle measuring device. Instead of using a coupling that is rotationally symmetrical at arbitrary angular positions as in the prior art, a coupling is used in which the coupling halves (10, 28) can be connected to one another only in a finite number of relative angular positions. An adjustment must be made before the coupling halves (10, 28) are attached to the respective rotors (46, 52). This allows all subsequent adjustment to be omitted, for example, even for maintenance work.

Temperature or vibration sensors (14) are often used, in addition to a transmitter (13), to monitor a motor (12). The aim of the invention is to simplify the transmission of the sensor signals of a plurality of sensor devices (13,14) mounted in or on a motor (12). To this end, an interface module (15) is mounted in or on a motor (12), especially in or on an electric motor, said interface module comprising a processing device for receiving and processing a first sensor signal emitted by a first sensor component (13). The first sensor component (13) is embodied in such a way as to detect a first physical variable and to emit the first sensor signal, and the processing device is embodied in such a way as to additionally receive and process a second sensor signal emitted by a second sensor component (14). The second sensor component (14) is used to detect a second physical variable and to emit the second sensor signal.

A method and apparatus for controlling the power of a transmit amplifier wherein a portion of the power transmitted from the antenna is received by a coupling element and is converted via a radio-frequency detector to a DC voltage value which is used for power control, such that there is no longer any need for complex use of a directional coupler between the transmit amplifier and the antenna.

A resectoscope has a shaft and a lock body which is slidable along the shaft and to which the proximal end portion of a resection electrode can be fixed. A handle is provided for displacing the lock body and thus the electrode along the shaft. The handle consists of a first portion connected to the lock body and projecting radially outwardly of the lock body and a second portion connected to the shaft, for engagement by a thumb of the user of the resectoscope. The first portion of the handle is formed as a disc provided with gripping aids for the user's fingers.

The aim of the invention is to reduce the resources required to monitor the bearings of an electric motor. To achieve this, the electric motor is equipped with an interface module (SM), which is used to calculate the remaining service life of a bearing (LA). Said interface module (SM) can be integrated into the motor or can be fitted to the latter. The remaining service life of the bearing (LA) can be estimated from the signal of a rotary transducer (GB) and optionally a temperature sensor (TS).

The aim of the invention is to increase the degree of automation in the production of an electrical machine. Particularly, the aim is to be able automate the connection of the coils of an electrical machine. For this purpose, provision is made for the coil ends (17) to be connected using at least one busbar (20, 22). The ends (23) of the respective busbars (20, 22) are hot crimped or welded to the associated end (17) of the coil. Thus, it is possible to eliminate manual drilling and welding of the coil ends. Moreover, the hot-crimped and welded connections have a high degree of electric strength and a high ampacity.
