Connectors are each integrated with a holder in a state in which bus bars are projected. A first projection and a second projection of the holder are respectively inserted in a first insertion hole and a second insertion hole in a circuit substrate. This determines positions of the holder and the circuit substrate relative to each other. The holder has coil lead wire insertion holes, capacitor lead wire insertion holes, and element lead wire insertion holes. These insertion holes extend in the same direction as the direction in which the bus bars project from the holder.

The invention relates to a rotary slide assembly and to a method for monitoring the wear of one or more slides in a rotary slide assembly, comprising a rotary slide rotor and one or more slide receiving areas for the slide(s) in the rotary slide rotor. The wear state of the one or more slides is detected during the operation or during a standstill of the rotary slide assembly. For this purpose, the slide(s) or one or more corresponding slide receiving areas in interaction with the one or more slides are used to generate or request an electric or electronic signal.

A climate-control system may include a compressor, a condenser, an evaporator, a first sensor, a second sensor, a third sensor, and a control module. The compressor may include a motor and a compression mechanism. The condenser receives compressed working fluid from the compressor. The evaporator is in fluid communication with the compressor and disposed downstream of the condenser and upstream of the compressor. The first sensor may detect an electrical operating parameter of the motor. The second sensor may detect a discharge temperature of working fluid discharged by the compression mechanism. The third sensor may detect a suction temperature of working fluid between the evaporator and the compression mechanism. The control module is in communication with the first, second and third sensors and may determine whether a refrigerant floodback condition is occurring in the compressor based on data received from the first, second and third sensors.
