Abstract: An improved system for connecting a DC bus cable and a remote motor drive includes a capacitance module and an extension module that may each be mounted adjacent to the remote motor drive. The capacitance module includes a first DC bus connector and a second DC bus connector. The first DC bus connector includes a terminal block configured to receive a pair of conductors for the DC bus. The first DC bus connector further includes a pair of intermediate bus bars where each of the intermediate bus bars are connected at a first end to the terminal block and at a second end to a circuit board contained within the capacitance module. Traces on the circuit board are routed between the second ends of the intermediate bus bars and the second DC bus connector. The second DC bus connector is configured to be connected to DC bus bars.

Abstract: An improved system for monitoring drive members in a belt-driven application during installation and during operation and for detecting common failure modes in belt-driven equipment is disclosed. Sensors are positioned within or proximate the motor housing to detect vibrations on the belt or in the electric machine. The vibration signals are used to monitor operating conditions and/or to identify the failure modes in belt-driven equipment. The vibration signals may be used, for example, to determine tension on a belt, detect either a static or dynamic force applied along the belt, a misalignment between a pulley and the belt, or a shock load applied to the belt during operation. By monitoring the various operating conditions of the belt-driven equipment, a controller may identify an existing failure mode or predict a premature failure mode.
