Abstract: An improved system for monitoring vibration of an electric machine is disclosed. According to one embodiment, sensors are positioned in a plane orthogonal to the motor shaft and each sensor detects vibration along at least one axis of the motor. The sensors are oriented such that the polarity of each sensor is reversed. The pairs of sensors may be used to isolate specific vibrations within the motor. According to another embodiment, a sensor may be mounted directly to the motor shaft. The sensor on the motor shaft directly detects vibrations along the motor shaft. Optionally, a second sensor may be mounted to a fixed location within the motor housing, and the combination of the sensor on the motor shaft and the sensor at a fixed location may be used to isolate specific vibrations within the motor. A motor controller may adjust operation of the motor to reduce the isolated vibration.

Abstract: A system for connecting a shared DC bus between multiple power converters is disclosed. The DC bus includes a positive and a negative rail across which the DC voltage is present. A pair of DC bus stabs is mounted to a PCB within the power converter. Each DC bus stab is electrically connected to either the positive or negative rail. A connector assembly is mounted to the housing of the power converter such that a first receptacle engages a plug portion of the DC bus stab. The connector assembly also includes a second receptacle extending to the exterior of the power converter. The connector assembly is positioned on each power converter such that a known distance, or one of a number of known distances, is established between adjacent connector assemblies. A DC bus assembly extends between and is plugged into the second receptacle of the two adjacent connector assemblies.
